**Testing the Performance of Electric Cars**

We had a unique opportunity to test the performance of electric cars at a test track, and we were joined by Julian, who was eager to put his car through its paces. We started with the Tesla EQXX, which is an electric car that is designed for long-range driving. However, since Julian wasn't insured on this segment of the track, we had to use him as a guinea pig instead. We set up a series of tests to measure the performance and efficiency of the car, including measuring the time it took to go from 0-60 mph and covering a quarter mile distance.

The test began with Julian getting into the car, and our engineer counting down from three to start the timer. As soon as the car started moving, Julian floored it, feeling the power of the electric motor propel him forward. The car accelerated quickly, reaching 0-60 mph in an impressive time of 15.87 seconds. However, the quarter mile distance was slower than expected, taking 11.57 seconds to complete.

The efficiency of the car was also measured during this test, with Julian's energy consumption coming out at 38.6 kilowatt hours per 100 kilometers. While not as efficient as some other electric cars on the market, it's still a respectable figure considering the car's performance. Our engineer noted that the power drops off at the top end of the acceleration, but overall, the car was able to deliver impressive results.

Next up was the Mercedes-AMG EQE 53, which is another electric car that we were eager to test. We set up a similar series of tests, including measuring the time it took for the car to go from 0-60 mph and covering a quarter mile distance. The results were even more impressive than those of the EQXX, with the AMG car reaching 0-60 mph in just 3.17 seconds.

However, when we measured the efficiency of the car, things got interesting. The energy consumption came out at 99.9 kilowatt hours per 100 kilometers, which is significantly lower than expected. Our engineer noted that this is likely due to the fact that the car was driven in a way that optimized its performance, rather than following the optimal driving profile.

Despite some issues with efficiency, our tests showed that the Mercedes-AMG EQE 53 is an extremely fast and capable electric car. Its performance was comparable to some of the fastest gas-powered cars on the market, including the legendary Nissan Skyline GT-R R32. While it may not be the most efficient car in terms of energy consumption, its ability to deliver impressive acceleration and handling makes it a compelling choice for drivers who value speed above all else.

In conclusion, our tests showed that both the Tesla EQXX and Mercedes-AMG EQE 53 are capable electric cars with impressive performance. While some issues were encountered during testing, including uneven efficiency results, these were largely due to the fact that we were pushing the cars to their limits in order to extract every last bit of performance from them. As a result, both cars demonstrate the potential for electric vehicles to deliver exceptional driving experiences and compete with traditional gas-powered cars.

**Special Equipment Used During Testing**

One of the key pieces of equipment used during our testing was a specialized timing device that allowed us to measure the acceleration and efficiency of each car in precise detail. This device is essential for getting accurate results when testing high-performance vehicles, as it provides a reliable and consistent way to capture data.

Another tool used during our tests was a measuring device that captured the energy consumption of each car. This allowed us to compare the efficiency of each vehicle and identify any patterns or trends in their behavior.

**Engineering Insights**

Our engineer noted that the AMG EQE 53 has a very different driving profile than some other electric cars on the market, which may explain its lower efficiency results. According to our engineer, this is because the car's power delivery is optimized for performance rather than efficiency, resulting in a more aggressive driving style.

This observation highlights an important trade-off that drivers of electric vehicles must consider when choosing their next vehicle. While some cars may be faster and more capable than others, they may also consume more energy and result in higher emissions. Ultimately, the best choice will depend on individual preferences and priorities.

**The Role of Engineering in Electric Vehicle Testing**

Engineering plays a crucial role in testing and evaluating the performance of electric vehicles like the Tesla EQXX and Mercedes-AMG EQE 53. By using specialized equipment and techniques to measure acceleration, efficiency, and other key performance metrics, engineers can gain a deep understanding of how each car behaves under different conditions.

This knowledge is essential for optimizing the performance of electric vehicles and identifying areas for improvement. It also provides valuable insights into the strengths and weaknesses of each vehicle, which can inform purchasing decisions and help drivers make the most of their next car.

**Conclusion**

Our tests provided a unique glimpse into the performance and capabilities of two exceptional electric cars: the Tesla EQXX and Mercedes-AMG EQE 53. While both vehicles showed impressive acceleration and handling, they also demonstrated some limitations in terms of efficiency and overall performance.

As the electric vehicle market continues to evolve and grow, it's likely that we'll see even more innovative solutions for improving performance and efficiency. For now, however, these two cars represent exciting examples of what can be achieved with the right combination of technology and engineering expertise.

"WEBVTTKind: captionsLanguage: enhi how are you matt watson here from car wow so i'm starting the mercedes-benz eqxx it is a record-breaking electric vehicle no other ev powered by a battery has gone further on a single charge this thing has driven from stuttgart in germany all the way to silverstone racing circuit in the united kingdom it clocked up 1202 kilometers and its average energy consumption was just 8.3 kilowatt hours per 100 kilometers travelled that is nuts however it could have done better you see mercedes made the mistake of handing it over to their formula e racing driver when he got to silverstone and he took it on the circuit for some hot laps which kind of ruined its efficiency ever so slightly so what i'm going to do here today is put the record straight i'm going to drive this car around a special circuit on mercedes test facility in germany i'm going to see what efficiency i can get out of this car but what i also want to do is compare its efficiency to a normal road going mercedes electric car so following me will be an eqe admittedly an amg 53 version but that doesn't matter and we're going to see how efficient that car is when driving at the same speed as this thing round the circuit but you know what electric cars aren't just about efficiency they're also about performance so of course we're going to launch this to see how quick it is from naught 60 miles an hour and over the standing quarter mile i'm also going to see just what doing that does to the efficiency so we'll measure the worst case scenario energy consumption of this car when you thrash it and once again we're going to compare that to when you thrash that eqe why well because i'm matt watson and you're watching car wow buy sell car wow i've been joined by julian from mercedes-benz who was one of the engineers responsible for this car so julian what you're going to do is reset my trip computer yes we're going to reset it what we also are going to do is give you the possibility to see exactly how much power you are using while driving discharge power or charging power and you're going to talk me through exactly how to drive this car as efficiently as possible yeah yes we have the guys behind us in the eqe trying to do the same i mean drive you're in drive that's perfect that was really really good now i would suggest you go to d minus minus because then you can drive pure one pedal drive you reckon that's better than coasting uh no as soon as you need coasting then you're going to switch to coasting with the paddles okay so start off because i'm just maneuvering in the most region as possible which is one pedal drive so i don't need to touch the brake unless it's an emergency yes let's go you turn left here keep in mind that uh you have to drive on the right-hand side because you are in europe yeah you noticed that didn't you straight away i wanted to go on the left yes you wanted on the correct side of the road yes which here is the right hand side okay now you could switch to d plus so that you do not recuperate okay so i'll pull on this paddle go to d plus yes and now when i lift off it will just coast yeah yeah you can just let it coast just to see how the feeling is so this is just rolling yeah you see how well the car rolls yeah this is like not even slowing down yeah this is something uh really really special with the car that it it's actually getting quicker it does actually it rolls so good because the drag is so low with the car it's been specifically engineered to have really low drag one of the key things about the eqxx is its design is all about being as aerodynamic as possible as you can see it's got a really long tail but you can extend it with this spoiler that sticks out now this doesn't create downforce it just reduces drag helps improve the aero in fact the area of this car is really really impressive has a drag coefficient of 0.17 cd now you can bear that with the eqs which has the low struct coefficient of any road car that's 0.2 cd and look at the shape of it as well the rear track is actually 50 millimeters narrower than the front because that helps keep these wheels in boarding as you'll notice they're blanked off so the spokes aren't exposed to reduce the drag 20 inch alloy wheels they may have magnesiums they're lightweight also the brake discs are made out of aluminium to help reduce the weight as well if you check out the design it's very sleek and if you look there's actually solar panels on the roof they can produce just over one kilowatt hour of electricity to power your ancillaries and that means you get an extra range of about 25 kilometers i've got to you something quite funny about this car so it's a four-door and it has a rear interior but you can't get to it if i open this door i always have a problem with mercedes handles i really like them look this door does not open the car was originally built as a two-door then the designers got involved and said you know why it needs to be a four-door design because it's more fitting with our road cars and indeed it should be but it was too late to change the actual structure of the car by the time they got round to that reason being this car has been developed so quickly from initial project sign-off to hitting the road and doing its world record run took just 22 months which is insane in the world of cars one thing i like about it is this they haven't used cameras for dormers like some other companies have for improved aero it's just a smaller sleeker mirror obviously you've got breathers around the front wheels to reduce drag then here at the front you have a couple of breathers there as well and these are the vents here to help cool the motors there's no vents to call the batteries reason being that they've used another technique there's aluminium plates underneath the car which conduct the heat away from the batch pack and then air rushes over those aluminium plates and then calls the battery pack down really really clever quite a nice design with this rose gold effect here then you've got little mercedes stars where a grill would be and then the mercedes badge here which isn't one of those pop-up style badges because they would produce a little bit of drag though i thought this would be painted on like on the amg one but it's just a sticker and some of these just stickers which is a little bit cheap feeling really and i'm sure that creates just a little bit of drag i want to sort of pick it off but probably shouldn't okay so just follow this round yeah yeah and then you turn right and you wanna well that's interesting over there so normally with electric cars they can be quite bumping the suspension that went over a little bump there it wasn't too bad at all it's a bit softer than i thought it would be this guy he knows us he's going to open the barrier for you we've got access all areas yeah this is your secret test facility we're going to see some prototypes we are going to see some prototypes as well uh don't talk about them okay don't look but don't tell anyone if you see some prototypes guys right yeah english who's this lady why she joined this is the lady who's watching us she is also going to talk to us when you are exceeding the speed limit it's all about safety so because we're on this test facility you're monitored the whole time the whole time yeah and there's also a guy like a physical human guy who's monitoring everything as well and if you exceed the speed limit too often then he's going to talk to you and he's going to talk to you in my name because you're driving here on my card so i can mess around all i want and you'll get in trouble yeah that's it okay so i'm going to coast down here right there's no point wow yeah when you lift off it just picks up speed yeah i don't want sandy says shot because yeah you think a car is going to go quicker as you're going downhill if you literally start to recuperate because over there you have to turn the left i've done it too fast it's good now you're trying to control it with your pedal you're going to get the feel for it you'll see just turn left i'm sorry yeah left i should have now i don't want to crash this because it's quite expensive that would be a problem but it is also unique we only have one of those i definitely don't want to crash it so now this is a twisty section so you get a feel for the steering and obviously you can tell this car just stays completely flat really in the bench it wasn't going particularly quickly to be fair but it feels pretty level obviously got the batteries as low down as possible which gives you a low center of gravity okay which way do you want me to go this way you leave the roundabout over there at the 50s do you know what we do in the uk that you guys in germany don't do we indicate when we're going round and then we indicate when we're getting off you only do one of those we only indicate when we're going off yeah because uh we drive our roundabouts only in one direction we turn away yes are you taking the piss but it's obvious no the direction you're going to take in the roundabout isn't it yeah it is yeah okay so now we're going upwards here um there you are allowed to drive 100 100 kilometers an hour okay so i'm going to build it up steadily though because we're going up here we don't want it yes you build up with around 30 kilowatts which is good then okay so i want to keep this kilowatt usage in between what parameters i would say in between 20 and 35 is good uh with what we have here so overall would the slower is better so if i would go a walking pace i would go further so when you did your run you'd have done it all at 10 kilometers an hour it would have taken longer but you'd have gone further yeah way further but this 20 to 30 is like optimal for performance and energy consumption is that what you're saying okay so how are you finding my regen am i a little bit too the speed of the car is not smooth enough now you go to d plus please okay let it roll down roll it you catch the speed when you go upwards to pick it up when we start to drop off a bit yeah now you can add something yes now you can pick it up it's good you can accelerate a bit more because speed limit over here 70 around about and now you see the road is going to get down again and then lift off lift off and let it coast yes and then you'll see it picks up speed how does it feel for you compared to other cars it's the lifting off and obviously i've been in other electric cars when they have a coast mode they don't feel like this this feels almost like a marble going down a hill the way it picks up speed you can tell there's very little friction so there's a lot of planning isn't there with this knowing when to lift off and coast and work your regen in the right way to maximize your efficiency so now i'm going to pick it up again it's quite good fun isn't it doing this probably not fun for the people behind you if you're going too slowly so here it goes down quite a lot quite a lot but then you see the corner over there so you don't want to pick up too much speed because the corner yeah 70 ish is a good spot to bring in a little bit of regen here that's it yeah so 17 to this corner yeah so just cruise at 70. cruise at 70. okay let's see how it does go into this yeah now you can cruise through the corner this is efficient driving if you want to narrow it down to a point then drive as constant as you can do not change the speed too much and you can drive constant the best when you look very far down the road in some ways it's a little bit like motorsport racing driving when you're looking as far ahead as possible to pick your lines but you're doing it to be as efficient as possible rather than as fast as possible the eqxx has a very special battery and this is it it's been built with the help of mercedes formula one team and it's really really compact you see this has 100 kilowatt hours of capacity which is about the same as the mercedes eqs however the volume of this battery is about half the size of the eqs's it's also 30 lighter so it weighs in at 495 kilos as opposed to 650 kilos it's also very efficient so a normal electric car would use about 90 of its battery capacity for propulsion the remaining 10 is used for ancillary stuff such as your sat nav and your air conditioning however everything about the eq xx is so efficient that 95 of the battery's power can be used for propulsion only five percent for those of the bits and pieces and the power itself goes to a single rear mounted motor which puts out 244 horsepower it's good for a top speed of 87 miles an hour which is 140 kilometers an hour as for the acceleration well i'm going to do a launch with the car in a bit so i'll find out exactly how quick it is because mercedes hasn't officially said i wonder if i'm doing well enough to beat that 8.3 kilowatt hours per 100 kilometers that you guys got on your journey i'm not sure you are on a good path to do so oh wicked i think if you continue like this and we'll improve a bit more then uh you'll do it i'm sure i'll tell you what's interesting i've driven a lot of concept cars and they're usually really rattly uncomfortable this is quiet it's relaxing it's quite finished isn't it for a concept and from an engineering point of view and also the workshop guys we're all really really proud of the car and we also worked together with colleagues from the uk from our formula one department and they brought some motorsport spirit into the project normally electric cars are really big and heavy because of their huge batteries despite the fact the eqxx has a huge battery it weighs 1750 kilos which is fairly light for an electric car with such an impressive range and one of the ways that mercedes has kept the weight down is to use some really clever technology in building the supporting structures for the car so this is the rear subframe and rather than being made up of 70 different pieces of metal like it would normally be for the amount of strength required for the car they've actually used an organic structure and the shape of this has been worked out by computer game engine and then what they've done is use that to 3d print a cast from which they formed this metal structure and i'll tell you what if that was made by old fashioned methods i would not have been able to lift it like that here's another example of similar technology once again computer game engine has worked out the strength required for making this mount which is for the windscreen wiper motor and they're only used bits of metal that they need for the strength and they've actually 3d printed this out of metal this weighs 200 grams normally it would weigh 2 kilos it's a 10th of the weight it would otherwise be now it's the same thing here with the front suspension mount this has been cast from a 3d printed mould as a result it's small efficient and light once again you can see the organic structure here by comparison this is the front suspension mount for a mercedes s-class which is made using normal production methods so just solid metal as a result it's quite heavy and big now you can actually see all these structures here on this model version the eqxx so there's the suspension mounts there's the mount for the windscreen wiper motor and there's the rear subframe yes it's nice and light and so too is the eq xxx when you consider it can do over 1000 kilometers or maybe more we'll find out in a moment there's one thing you forgot to do you haven't done any donuts in it it's rear-wheel drive i saw the skid pan there should we just nip back and go do some donuts no no no donuts today oh it's it's not the amg version is it uh this one not does it feel like it well there's a tractor i don't want to break this is the problem this is the problem yes exactly this is especially when you're driving something that's as expensive as this you know like millions and millions and millions of euros and the bloody tractor pulls out and i don't know whether i want to stop or not i didn't stop that could have been really bad 70 again oh would it hold on we've got low friction tires and they're pumped up quite a lot but it yeah it's fine it's fine it feels good we're not really pushing it that hard though come on oh here we go here's a straight let's see if we can get you in trouble here is 100 speed limit do you know what i've done on this straight i've actually launched a load of classic mercedes some of them which are worth millions now if you want to watch that video just click okay i'm sorry you can do let the car do the job no that's okay just uh long long press on the right now you see the auto okay and now just let the car roll and you'll do its thing it should do the recuperation for you because there's a roundabout about your car so it's going to be so it's going to figure out where to brake and recuperate okay but you know what you did though julian you accidentally interrupted a very important plug to another one of our videos which is another mercedes video so you've got to point up there like that and tell people to click there just point and go click here click here please there we go now you see the car okay yeah it's just the car is now slot you can put your hand down now the car look at this is brilliant yeah so ah is it gonna is it just really trust me trust me okay so now i take control yeah now you can take control yeah so that was really weird it just slowed the car down the right amount to get me around that corner yeah and it was really really efficient i would say a bit more efficient than you could have done in that particular case because you couldn't see this corner because it was uh downward somewhere you didn't see it and now it's recuperating you to keep the speed you see oh this is good this is assisting you yeah it's speeding you program the car to speed it's 50. it's doing like 54. yeah and now so i can go around here without without braking without braking yes ah you see we've built up some trust to us yeah it's good i trust you now it's good here we turn left then right right so julian you you managed to engineer a car that can do over a thousand kilometers on one charge but you don't know the difference between left and right i think you need to go back to school yeah i could do so not engineering school not gonna lie to you julian the brake pedal feels a bit weird does it a little bit i don't use it i can tell i think on your road going electric cars it's a little bit better calibrated just saying don't take offense no offense taken it was clearly not the focus with this project yes here we turn left sorry so that's left left left left not right left yeah yeah we agreed right now okay uh left and right i'll stop with that gag i think everyone's pretty bored of it especially you i'm going to stop with recuperation don't do it too much so i'm using the pedals now to just slow it exactly as i want it come on stop stop stop stop stop i did it i'm good yeah okay i can break now you can break because now we're rolling backwards i'm really interested to see exactly how efficient i was and find out exactly how i did how compared to when you guys did it on the road and how this car compared to that amg and then after we've done that we're going to launch them yeah yeah let's do it okay so we've got the details of all my driving data here and we can see that i drove for 15.74 kilometers an average speed of 45 kilometers an hour and my average consumption was 8.2 kilowatt hours per 100 kilometers and when you do the maths based on the battery capacity i would have driven on a full charge a total of 1220 kilometers so further than you did on the road yes that's enough anyway if you look here at my driver profile we actually have a pro driver so julian here what he did when he drove the test course and you can see my profile mine's the blue profile and this is my energy consumption there so i'm doing better in this stage than julian did so he averaged 7.9 kilowatt hours per 100 kilometers and he was going slightly faster as well so a bit better but i blame the slight shortfall on the fact that tractor pulled out on me otherwise i'd have beaten him do you reckon yeah it might have been closer without the tractor driving in there that's true but totally attractive well you would have been slower as a tractor you sure absolutely should we launched the cars let's know before we do this before we do though the amg eqe so that averaged 19.9 on the same route on the same route which is quite a bit more when you work out its batch capacity of 90.6 kilowatt hours that means that would have done 455 yes kilometers on a single charge so going more than twice as far anyway now let's launch them okay now we're going to launch the mercedes-benz eqx to see how quick it is from naught 60 miles an hour and over the standing quarter mile unfortunately i can't drive it because i'm not insured on this segment of the test track so we're gonna get julian to do it so it's all on you and what we're gonna do is measure the time but also we're gonna measure the energy consumption as well right i'll count you in three two one go oh a bit slower than i thought it would be off the line so naught 60 is coming up now 7.5 7.51 what is the quarter mile though keep pushing keep pushing come on so the power drops off at the top end but we've got a quarter mile time of 15.87 seconds so hard break so you don't want to do too much regen and what was that energy consumption 38.6 ooh 38.6 kilowatt hours per 100 kilometers yes i'm much more efficient than you you're rubbish yes well uh it was a different driving profile i wouldn't i know i would i totally won so what i found interesting was it was quite slow feeling off the mark but the time we put in for not 60 was respectable 7.5 but if you just floor it now go and hit hit the accelerator fully yeah the pickup yeah is better isn't it once you're rolling so when you need to overtake a car it's it's faster than that number 7.5 yeah suggests overtaking it's like the the low end torque is not that high of the car because it's engineered for highway speeds the power of the car with 180 kilowatts is quite high but you only get that power from above a certain speed so if i uh do full throttle right now at 30kps right let's just test it with my special g measuring device here go on then say floor it yeah it's better isn't it yeah and when i get faster it's getting even better yes look at this this is science do you use one of these in your testing while developing the car yeah always but they are calibrated a bit more thoroughly engineer jokes do you know what julian that time he just got over the standing quarter mile was pretty much the same that i got from an r32 nissan skyline gtr and that obviously is known as a fast car so it's not too bad really anyhow we've now jumped into the amg eqe 53 and we're going to launch it see how quick it is from 260 and also measure the efficiencies got my specialist timing gear up here when you're ready launch it let's see what we do oh yeah that's more brutal so naught 16 is coming up quicker and it's 3.17 seconds what's the what's the quarter mile it is 11.57 yeah it's better than the eqxx isn't it but what about the efficiency 99.9 kilowatt hours per 100 so i'm afraid it went to the maximum that it displays i'm sorry so basically do you think it went higher than 99.9 then i'm absolutely sure what do you reckon using your engineering knowledge and expertise might be doubled it really have been way faster than 140 and you have to take into account at those high speeds the drag is way higher because the air drag goes into the calculation in the square of it of the speed you know so the air drag force at 200 is four times the force then you have to go at 100. it's less efficient yes but we have been faster i mean it's less efficient and we have been faster and i mean obviously you need to put energy in there to get fast so we did not drive exactly the same trajectory speed wise so we it's hard there we go but the acceleration was good like here now it's obviously the pickup compared to the eqxx yeah yeah i'm sorry you know what it's really quick isn't it considering it's a 53 model and not a 63 it's really pretty quick it's awesome let's do it no no no no no okay in fact wait wait wait wait right ready go take care of your nose do it again i like hurting myself now if you want to hurt me again you can visit whether you really want to hurt me again yeah i want more i'm sorry that's a bit kind of weird it got a bit s m there didn't it julian let's just wrap this up here anyway i hope you enjoyed the video if you did give it a like let me know what you think of the eq xxx in the comments below click on those windows there right for some more videos and click on that box there to go to the car word see how much you can get for your car you just upload some photos give a brief description then adding is a bid on your car and on average 83 percent of the people get better prices through carway thanks for watchinghi how are you matt watson here from car wow so i'm starting the mercedes-benz eqxx it is a record-breaking electric vehicle no other ev powered by a battery has gone further on a single charge this thing has driven from stuttgart in germany all the way to silverstone racing circuit in the united kingdom it clocked up 1202 kilometers and its average energy consumption was just 8.3 kilowatt hours per 100 kilometers travelled that is nuts however it could have done better you see mercedes made the mistake of handing it over to their formula e racing driver when he got to silverstone and he took it on the circuit for some hot laps which kind of ruined its efficiency ever so slightly so what i'm going to do here today is put the record straight i'm going to drive this car around a special circuit on mercedes test facility in germany i'm going to see what

also about performance so of course we're going to launch this to see how quick it is from naught 60 miles an hour and over the standing quarter mile i'm also going to see just what doing that does to the efficiency so we'll measure the worst case scenario energy consumption of this car when you thrash it and once again we're going to compare that to when you thrash that eqe why well because i'm matt watson and you're watching car wow buy sell car wow i've been joined by julian from mercedes-benz who was one of the engineers responsible for this car so julian what you're going to do is reset my trip computer yes we're going to reset it what we also are going to do is give you the possibility to see exactly how much power you are using while driving discharge power or charging power and you're going to talk me through exactly how to drive this car as efficiently as possible yeah yes we have the guys behind us in the eqe trying to do the same i mean drive you're in drive that's perfect that was really really good now i would suggest you go to d minus minus because then you can drive pure one pedal drive you reckon that's better than coasting uh no as soon as you need coasting then you're going to switch to coasting with the paddles okay so start off because i'm just maneuvering in the most region as possible which is one pedal drive so i don't need to touch the brake unless it's an emergency yes let's go you turn left here keep in mind that uh you have to drive on the right-hand side because you are in europe yeah you noticed that didn't you straight away i wanted to go on the left yes you wanted on the correct side of the road yes which here is the right hand side okay now you could switch to d plus so that you do not recuperate okay so i'll pull on this paddle go to d plus yes and now when i lift off it will just coast yeah yeah you can just let it coast just to see how the feeling is so this is just rolling yeah you see how well the car rolls yeah this is like not even slowing down yeah this is something uh really really special with the car that it it's actually getting quicker it does actually it rolls so good because the drag is so low with the car it's been specifically engineered to have really low drag one of the key things about the eqxx is its design is all about being as aerodynamic as possible as you can see it's got a really

has a drag coefficient of 0.17 cd now you can bear that with the eqs which has the low struct coefficient of any road car that's 0.2 cd and look at the shape of it as well the rear track is actually 50 millimeters narrower than the front because that helps keep these wheels in boarding as you'll notice they're blanked off so the spokes aren't exposed to reduce the drag 20 inch alloy wheels they may have magnesiums they're lightweight also the brake discs are made out of aluminium to help reduce the weight as well if you check out the design it's very sleek and if you look there's actually solar panels on the roof they can produce just over one kilowatt hour of electricity to power your ancillaries and that means you get an extra range of about 25 kilometers i've got to you something quite funny about this car so it's a four-door and it has a rear interior but you can't get to it if i open this door i always have a problem with mercedes handles i really like them look this door does not open the car was originally built as a two-door then the designers got involved and said you know why it needs to be a four-door design because it's more fitting with our road cars and indeed it should be but it was too late to change the actual structure of the car by the time they got round to that reason being this car has been developed so quickly from initial project sign-off to hitting the road and doing its world record run took just 22 months which is insane in the world of cars one thing i like about it is this they haven't used cameras for dormers like some other companies have for improved aero it's just a smaller sleeker mirror obviously you've got breathers around the front wheels to reduce drag then here at the front you have a couple of breathers there as well and these are the vents here to help cool the motors there's no vents to call the batteries reason being that they've used another technique there's aluminium plates underneath the car which conduct the heat away from the batch pack and then air rushes over those aluminium plates and then calls the battery pack down really really clever quite a nice design with this rose gold effect here then you've got little mercedes stars where a grill would be and then the mercedes badge here which isn't one of those pop-up style badges because they would produce a little bit of drag though i thought this would be painted on like on the amg one but it's just a sticker and some of these just stickers which is a little bit cheap feeling really and i'm sure that creates just a little bit of drag i want to sort of pick it off but probably shouldn't okay so just follow this round yeah yeah and then you turn right and you wanna well that's interesting over there so normally with electric cars they can be quite bumping the suspension that went over a little bump there it wasn't too bad at all it's a bit softer than i thought it would be this guy he knows us he's going to open the barrier for you we've got access all areas yeah this is your secret test facility we're going to see some prototypes we are going to see some prototypes as well uh don't talk about them okay don't look but don't tell anyone if you see some prototypes guys right yeah english who's this lady why she joined this is the lady who's watching us she is also going to talk to us when you are exceeding the speed limit it's all about safety so because we're on this test facility you're monitored the whole time the whole time yeah and there's also a guy like a physical human guy who's monitoring everything as well and if you exceed the speed limit too often then he's going to talk to you and he's going to talk to you in my name because you're driving here on my card so i can mess around all i want and you'll get in trouble yeah that's it okay so i'm going to coast down here right there's no point wow yeah when you lift off it just picks up speed yeah i don't want sandy says shot because yeah you think a car is going to go quicker as you're going downhill if you literally start to recuperate because over there you have to turn the left i've done it too fast it's good now you're trying to control it with your pedal you're going to get the feel for it you'll see just turn left i'm sorry yeah left i should have now i don't want to crash this because it's quite expensive that would be a problem but it is also unique we only have one of those i definitely don't want to crash it so now this is a twisty section so you get a feel for the steering and obviously you can tell this car just stays completely flat really in the bench it wasn't going particularly quickly to be fair but it feels pretty level obviously got the batteries as low down as possible which gives you a low center of gravity okay which way do you want me to go this way you leave the roundabout over there at the 50s do you know what we do in the uk that you guys in germany don't do we indicate when we're going round and then we indicate when we're getting off you only do one of those we only indicate when we're going off yeah because uh we drive our roundabouts only in one direction we turn away yes are you taking the piss but it's obvious no the direction you're going to take in the roundabout isn't it yeah it is yeah okay so now we're going upwards here um there you are allowed to drive 100 100 kilometers an hour okay so i'm going to build it up steadily though because we're going up here we don't want it yes you build up with around 30 kilowatts which is good then okay so i want to keep this kilowatt usage in between what parameters i would say in between 20 and 35 is good uh with what we have here so overall would the slower is better so if i would go a walking pace i would go further so when you did your run you'd have done it all at 10 kilometers an hour it would have taken longer but you'd have gone further yeah way further but this 20 to 30 is like optimal for performance and energy consumption is that what you're saying okay so how are you finding my regen am i a little bit too the speed of the car is not smooth enough now you go to d plus please okay let it roll down roll it you catch the speed when you go upwards to pick it up when we start to drop off a bit yeah now you can add something yes now you can pick it up it's good you can accelerate a bit more because speed limit over here 70 around about and now you see the road is going to get down again and then lift off lift off and let it coast yes and then you'll see it picks up speed how does it feel for you compared to other cars it's the lifting off and obviously i've been in other electric cars when they have a coast mode they don't feel like this this feels almost like a marble going down a hill the way it picks up speed you can tell there's very little friction so there's a lot of planning isn't there with this knowing when to lift off and coast and work your regen in the right way to maximize your efficiency so now i'm going to pick it up again it's quite good fun isn't it doing this probably not fun for the people behind you if you're going too slowly so here it goes down quite a lot quite a lot but then you see the corner over there so you don't want to pick up too much speed because the corner yeah 70 ish is a good spot to bring in a little bit of regen here that's it yeah so 17 to this corner yeah so just cruise at 70. cruise at 70. okay let's see how it does go into this yeah now you can cruise through the corner this is efficient driving if you want to narrow it down to a point then drive as constant as you can do not change the speed too much and you can drive constant the best when you look very far down the road in some ways it's a little bit like motorsport racing driving when you're looking as far ahead as possible to pick your lines but you're doing it to be as efficient as possible rather than as fast as possible the eqxx has a very special battery and this is it it's been built with the help of mercedes formula one team and it's really really compact you see this has 100 kilowatt hours of capacity which is about the same as the mercedes eqs however the volume of this battery is about half the size of the eqs's it's also 30 lighter so it weighs in at 495 kilos as opposed to 650 kilos it's also very efficient so a normal electric car would use about 90 of its battery capacity for propulsion the remaining 10 is used for ancillary stuff such as your sat nav and your air conditioning however everything about the eq xx is so efficient that 95 of the battery's power can be used for propulsion only five percent for those of the bits and pieces and the power itself goes to a single rear mounted motor which puts out 244 horsepower it's good for a top speed of 87 miles an hour which is 140 kilometers an hour as for the acceleration well i'm going to do a launch with the car in a bit so i'll find out exactly how quick it is because mercedes hasn't officially said i wonder if i'm doing well enough to beat that 8.3 kilowatt hours per 100 kilometers that you guys got on your journey i'm not sure you are on a good path to do so oh wicked i think if you continue like this and we'll improve a bit more then uh you'll do it i'm sure i'll tell you what's interesting i've driven a lot of concept cars and they're usually really rattly uncomfortable this is quiet it's relaxing it's quite finished isn't it for a concept and from an engineering point of view and also the workshop guys we're all really really proud of the car and we also worked together with colleagues from the uk from our formula one department and they brought some motorsport spirit into the project normally electric cars are really big and heavy because of their huge batteries despite the fact the eqxx has a huge battery it weighs 1750 kilos which is fairly light for an electric car with such an impressive range and one of the ways that mercedes has kept the weight down is to use some really clever technology in building the supporting structures for the car so this is the rear subframe and rather than being made up of 70 different pieces of metal like it would normally be for the amount of strength required for the car they've actually used an organic structure and the shape of this has been worked out by computer game engine and then what they've done is use that to 3d print a cast from which they formed this metal structure and i'll tell you what if that was made by old fashioned methods i would not have been able to lift it like that here's another example of similar technology once again computer game engine has worked out the strength required for making this mount which is for the windscreen wiper motor and they're only used bits of metal that they need for the strength and they've actually 3d printed this out of metal this weighs 200 grams normally it would weigh 2 kilos it's a 10th of the weight it would otherwise be now it's the same thing here with the front suspension mount this has been cast from a 3d printed mould as a result it's small efficient and light once again you can see the organic structure here by comparison this is the front suspension mount for a mercedes s-class which is made using normal production methods so just solid metal as a result it's quite heavy and big now you can actually see all these structures here on this model version the eqxx so there's the suspension mounts there's the mount for the windscreen wiper motor and there's the rear subframe yes it's nice and light and so too is the eq xxx when you consider it can do over 1000 kilometers or maybe more we'll find out in a moment there's one thing you forgot to do you haven't done any donuts in it it's rear-wheel drive i saw the skid pan there should we just nip back and go do some donuts no no no donuts today oh it's it's not the amg version is it uh this one not does it feel like it well there's a tractor i don't want to break this is the problem this is the problem yes exactly this is especially when you're driving something that's as expensive as this you know like millions and millions and millions of euros and the bloody tractor pulls out and i don't know whether i want to stop or not i didn't stop that could have been really bad 70 again oh would it hold on we've got low friction tires and they're pumped up quite a lot but it yeah it's fine it's fine it feels good we're not really pushing it that hard though come on oh here we go here's a straight let's see if we can get you in trouble here is 100 speed limit do you know what i've done on this straight i've actually launched a load of classic mercedes some of them which are worth millions now if you want to watch that video just click okay i'm sorry you can do let the car do the job no that's okay just uh long long press on the right now you see the auto okay and now just let the car roll and you'll do its thing it should do the recuperation for you because there's a roundabout about your car so it's going to be so it's going to figure out where to brake and recuperate okay but you know what you did though julian you accidentally interrupted a very important plug to another one of our videos which is another mercedes video so you've got to point up there like that and tell people to click there just point and go click here click here please there we go now you see the car okay yeah it's just the car is now slot you can put your hand down now the car look at this is brilliant yeah so ah is it gonna is it just really trust me trust me okay so now i take control yeah now you can take control yeah so that was really weird it just slowed the car down the right amount to get me around that corner yeah and it was really really efficient i would say a bit more efficient than you could have done in that particular case because you couldn't see this corner because it was uh downward somewhere you didn't see it and now it's recuperating you to keep the speed you see oh this is good this is assisting you yeah it's speeding you program the car to speed it's 50. it's doing like 54. yeah and now so i can go around here without without braking without braking yes ah you see we've built up some trust to us yeah it's good i trust you now it's good here we turn left then right right so julian you you managed to engineer a car that can do over a thousand kilometers on one charge but you don't know the difference between left and right i think you need to go back to school yeah i could do so not engineering school not gonna lie to you julian the brake pedal feels a bit weird does it a little bit i don't use it i can tell i think on your road going electric cars it's a little bit better calibrated just saying don't take offense no offense taken it was clearly not the focus with this project yes here we turn left sorry so that's left left left left not right left yeah yeah we agreed right now okay uh left and right i'll stop with that gag i think everyone's pretty bored of it especially you i'm going to stop with recuperation don't do it too much so i'm using the pedals now to just slow it exactly as i want it come on stop stop stop stop stop i did it i'm good yeah okay i can break now you can break because now we're rolling backwards i'm really interested to see exactly how efficient i was and find out exactly how i did how compared to when you guys did it on the road and how this car compared to that amg and then after we've done that we're going to launch them yeah yeah let's do it okay so we've got the details of all my driving data here and we can see that i drove for 15.74 kilometers an average speed of 45 kilometers an hour and my average consumption was 8.2 kilowatt hours per 100 kilometers and when you do the maths based on the battery capacity i would have driven on a full charge a total of 1220 kilometers so further than you did on the road yes that's enough anyway if you look here at my driver profile we actually have a pro driver so julian here what he did when he drove the test course and you can see my profile mine's the blue profile and this is my energy consumption there so i'm doing better in this stage than julian did so he averaged 7.9 kilowatt hours per 100 kilometers and he was going slightly faster as well so a bit better but i blame the slight shortfall on the fact that tractor pulled out on me otherwise i'd have beaten him do you reckon yeah it might have been closer without the tractor driving in there that's true but totally attractive well you would have been slower as a tractor you sure absolutely should we launched the cars let's know before we do this before we do though the amg eqe so that averaged 19.9 on the same route on the same route which is quite a bit more when you work out its batch capacity of 90.6 kilowatt hours that means that would have done 455 yes kilometers on a single charge so going more than twice as far anyway now let's launch them okay now we're going to launch the mercedes-benz eqx to see how quick it is from naught 60 miles an hour and over the standing quarter mile unfortunately i can't drive it because i'm not insured on this segment of the test track so we're gonna get julian to do it so it's all on you and what we're gonna do is measure the time but also we're gonna measure the energy consumption as well right i'll count you in three two one go oh a bit slower than i thought it would be off the line so naught 60 is coming up now 7.5 7.51 what is the quarter mile though keep pushing keep pushing come on so the power drops off at the top end but we've got a quarter mile time of 15.87 seconds so hard break so you don't want to do too much regen and what was that energy consumption 38.6 ooh 38.6 kilowatt hours per 100 kilometers yes i'm much more efficient than you you're rubbish yes well uh it was a different driving profile i wouldn't i know i would i totally won so what i found interesting was it was quite slow feeling off the mark but the time we put in for not 60 was respectable 7.5 but if you just floor it now go and hit hit the accelerator fully yeah the pickup yeah is better isn't it once you're rolling so when you need to overtake a car it's it's faster than that number 7.5 yeah suggests overtaking it's like the the low end torque is not that high of the car because it's engineered for highway speeds the power of the car with 180 kilowatts is quite high but you only get that power from above a certain speed so if i uh do full throttle right now at 30kps right let's just test it with my special g measuring device here go on then say floor it yeah it's better isn't it yeah and when i get faster it's getting even better yes look at this this is science do you use one of these in your testing while developing the car yeah always but they are calibrated a bit more thoroughly engineer jokes do you know what julian that time he just got over the standing quarter mile was pretty much the same that i got from an r32 nissan skyline gtr and that obviously is known as a fast car so it's not too bad really anyhow we've now jumped into the amg eqe 53 and we're going to launch it see how quick it is from 260 and also measure the efficiencies got my specialist timing gear up here when you're ready launch it let's see what we do oh yeah that's more brutal so naught 16 is coming up quicker and it's 3.17 seconds what's the what's the quarter mile it is 11.57 yeah it's better than the eqxx isn't it but what about the efficiency 99.9 kilowatt hours per 100 so i'm afraid it went to the maximum that it displays i'm sorry so basically do you think it went higher than 99.9 then i'm absolutely sure what do you reckon using your engineering knowledge and expertise might be doubled it really have been way faster than 140 and you have to take into account at those high speeds the drag is way higher because the air drag goes into the calculation in the square of it of the speed you know so the air drag force at 200 is four times the force then you have to go at 100. it's less efficient yes but we have been faster i mean it's less efficient and we have been faster and i mean obviously you need to put energy in there to get fast so we did not drive exactly the same trajectory speed wise so we it's hard there we go but the acceleration was good like here now it's obviously the pickup compared to the eqxx yeah yeah i'm sorry you know what it's really quick isn't it considering it's a 53 model and not a 63 it's really pretty quick it's awesome let's do it no no no no no okay in fact wait wait wait wait right ready go take care of your nose do it again i like hurting myself now if you want to hurt me again you can visit whether you really want to hurt me again yeah i want more i'm sorry that's a bit kind of weird it got a bit s m there didn't it julian let's just wrap this up here anyway i hope you enjoyed the video if you did give it a like let me know what you think of the eq xxx in the comments below click on those windows there right for some more videos and click on that box there to go to the car word see how much you can get for your car you just upload some photos give a brief description then adding is a bid on your car and on average 83 percent of the people get better prices through carway
