**A Rolling Race: A Test of Speed and Traction**
The video begins with the presenter explaining that they have found a great deal on a car through CarWow, an online marketplace for buying and selling cars. The presenter notes that over 4,000 dealers are listed on CarWow, offering customers a wide range of options to find their next vehicle. With the help of CarWow, the presenter was able to purchase this particular car at a price they expected or more.
The presenter decides to put this new car through its paces with a rolling race against another car. The two cars are set up in a straight line, and the presenter explains that they will be racing from 30 miles per hour to the half mile mark. The rules of the race are simple: whoever crosses the finish line first wins. The presenter then calls out "3-2-1 go!" and the two cars take off.
The presenter notes that the car was initially a bit tricky to handle, but as they gained speed, it became more reliable. They comment on how much traction issues there were at the beginning of the race, but once they reached 50 miles per hour in third gear, the car's performance improved significantly. The presenter also mentions that their opponent had a hard time getting started and was struggling to keep up with them.
Despite the initial struggles, the presenter notes that as the cars approached the finish line, their opponent began to gain ground. However, the presenter believes that they were still in the lead until the very end of the race. The presenter acknowledges that there were some issues with gear changes during the race, but overall, the car performed well.
To further test the car's performance, the presenter calls up another set of gears and performs a second rolling race from 30 miles per hour to the half mile mark. This time, they start in third gear, hoping to eliminate any traction issues that may have been present earlier. The presenter notes that this approach allows them to compare the torque and power of the car more accurately.
The second rolling race produces similar results as the first: the presenter is initially ahead but their opponent begins to catch up towards the end. However, by performing in third gear, the presenter believes they were able to gain a slight advantage. They comment that the car's performance improved significantly once they reached 50 miles per hour.
To further compare the car's performance, the presenter decides to perform one more rolling race from 30 miles per hour to the half mile mark in third gear. This time, they also decide to take traction out of consideration by performing at a higher speed and removing any driving aids that may be present. The presenter believes this will give them a better idea of how the car performs compared to their opponent.
The final rolling race is performed with full emergency stop at 100 miles per hour, where both drivers slam on the brakes as hard as possible. Both cars come to a sudden stop, and it becomes clear that there was indeed an advantage in terms of traction difference between the two tires.
**A Safety Feature: Tire Choice**
The presenter comments on how much tire choice makes a big difference not only when accelerating and putting down power but also when stopping. They explain that having cup-twos as well as other tires can make a significant impact on a car's performance, particularly in terms of traction and braking ability.
In particular, the presenter notes that having warm tires (such as those warmed up by air brakes) is crucial for safety reasons. The presenter explains that this feature helps protect pedestrians once they are warmed up, as it reduces the risk of tire blowouts or loss of control.
The presenter also mentions their idea to incorporate heaters in the wheel arches to warm up the tires even quicker. They believe this could be a useful innovation for improving traction and safety on wet roads.
**A Big Thank You**
Finally, the presenter expresses their gratitude to the people who lent them the car, as well as Andy for bringing his 720S along to perform brilliantly in the rolling race. The presenter also thanks CarWow for making it possible to find such a great deal on this car, and encourages viewers to check out their website to see how other cars compare to this one.
The video ends with a call to action, inviting viewers to watch more drag racing videos featuring this car, as well as the opportunity to view the current leaderboard.
"WEBVTTKind: captionsLanguage: enwhat will'll win in a drag race between the old McLaren 720s and this the new McLaren 750s we're going to find out by racing them over the standing quarter mile I'm Matt Watson and you're watching carw right let me tell you no in fact no I'm not going to tell you let's start off with Andy also known as the car filming safety guide telling you everything about the 720 hi Andy how are you hello Matt I'm all good thanks back thanks for coming back with your 720s which last time I spoke to you had not put a foot wrong in what was it a year or two years of ownership which is quite unusual for McLaren sorry Mclaren has it gone wrong yet well there was some bubbling on the panels but McLaren wonderfully under the warranty replaced the Bonnet and the front Wings in the door resp sprayed it all picked it up brought it back to me no charge thank you very much okay so something has gone wrong but it wasn't mechanical however there was bubbling on the paint workor which makes me think that it was rusting but it doesn't have metal body panels does it yeah something to do with some earlier mcclaren's had some moisture content in the carbon molds um but yeah it was all done by them and apart from that yeah it's been great 13,000 Mi Now give me the stats on that car 4 L twin turbo V8 720 horsepower 770 newm of torque 7speed dual clutch weighing 1.4 ton this car has similar engine but they've increased power to 750 horsepower and I got more torque up by 30 n m to 8 800 NM still got a 7-speed dual clutch automatic gearbox rear wheel drive and the weight is pretty similar as well there is another difference which might matter in this drag race cuz it'll help the car put its power down this has a proper limited slip differential whereas that car doesn't does it I'm afraid not B weird I was always surprised they never had a diff in those cars they always claimed it was about weight reduction blah blah blah blah blah but here we are they finally learned and they've put one in because it doesn't add that much extra weight and it really does help proov traction anyway will it affect the drag race well we're going to find out but before we do find out we're going to do the customary call our sound check so I'm going to rev up this 750 sounds pretty good rev up your car Andy yeah they sound very similar don't they surprise surprise I think that's a good time to get one with the race 3 2 1 a will spit off the line but hooked up better than his car now he's getting dropped I reckon this could go quick pretty sure that his can as well I don't think your car hooked up particularly well there andy launch control was working it was good but yeah there's not a lot in it once we're off the line well we'll find out because we're going to do it again so I didn't hook up as well as I could do I reckon I've got better time in me and I reckon you've definitely got a better time in you cuz I shouldn't be that far ahead and I think it was just that initial launch off the line I thought with the better gearing that yours should have the shorter gear in I thought we would have been much further in front oh wait there andy you're telling me something I don't know about this car I clearly haven't done my research so it's also got shorter gearing than your car I may be wrong but there's isn't there something about the 765 gearing or it's got different gearing or something I might be wrong right we're going to get an Editor to put on screen now does this car have shorter gearing if so by how much 3 2 1 pretty close but this just picked up a bit better that was better that time you got a better launch but still it's beat you quite convincingly I'm afraid so normally I do best two out of three which means that it'd be game over but let's call the first drag racer practice and go again so best three out of five 3 2 one oh NE neck on the light fact he got a better jump on me here we go oh when I skipped over a jump is going to take me this time oh good work now that's what I'm talking about so this car had a little bit of an issue off the line it lost a bit of traction and then it went over a jump and it sort of skipped a bit but you were gone your launch was so good now awesome I'm up to 35° on the rear tires now which is probably helping me cuz you're on P Zer I think yeah I am mine is saying 38 on the one 35 on the other so you got some heat in those cup twos let's go again 3 2 1 add me off the line again get the we skipping then but it's not my best time it's getting slower so Andy this is really interesting my car's getting slightly slower and your is getting quicker as the tires warm up it's cup twos once they're in heat they are so good I said best three out of five it's two each it's the decider 3 2 1 got to way better that time so I'm an honest chap Andy um let me just check something Stuart can you just double check I didn't jump no no jump to I think you might have been a bit slow off the line that time I'm afraid Andy what's interesting is though once they're off the line there's very little in it the rolling start is going to be really interesting before we do that Andy let's just do the numbers so then what exactly happened well the 750s W it completed the standing quarter mile in 10.5 seconds the 720s talk 10.8 seconds want to sell your car quickly easily and for a fair price then head to car while to have over 4,000 trusted dealers ready to bid on it in an online auction first enter your car's registration to get an instant approximate valuation then if you want to

93% of sellers surveyed said they got the price they expected or more through carw the best bit is it's completely free I put a link in the description of this video and the Ping comment to take you directly to carwow we over 4,000 d dealers are ready to bid on your car or you can just click on the pop out Banner that should be appearing in the top right hand corner of the screen now alternatively just Google help me carwow and we will help you sell your car quickly easily and for a fair price on with the video okay now we GA a rolling race second gear from 30 m hour to the half mile let's do it 3 2 1 go oh that was really interesting I think you just won just by the narrowest a margin for one moment I was ahead of you then I was behind you then I was that's what I think happened and this lost a bit of traction at one point and that's when you just came back past me and then that was it yeah I fluffed up a gear change I hit the rev limit which took a little bit off but yeah interestingly I didn't lose traction at all cup twos mate I'm on pellis Frid so cup twos best tire ever let's do it again without a cocked up gear change okay second gear again 30 m act 3 2 1 go that's faster it is yeah I think had a tiny bit of wheel spin but yeah it's faster it's a bit awkward isn't it it is what it is you know what let's take the traction out of it by doing it from 50 in third then there shouldn't be traction issues and we'll you'll just be able to compare the torque and the actual power then without Traction in your better tires 3 2 1 go uh not necessarily the tires is it so you're in track mode yeah I'm in track Dynamic ESC track handling track everything let's do one more of those just to take any lightting consistencies with the gearbox out right here we go let's get to 50 I'll call it in 3 2 1 go all right so that was interesting I don't think you got a good pickup from the beginning then but once we were going although I was ahead towards the end did you notice you reeling me in yeah yeah it was catching up once it's going yeah so I think we need to do just one more of those in third gear cuz it's still not conclusive let's go 3 2 1 go that didn't answer any more questions really I do still think you were really me back in at the top end but this the last two runs that I did I noticed that there was no traction issues and the car just performed slightly better but I'm sure at the top end you were still just pulling me back don't you think yeah yeah it was catching up about a car length towards the end but that's the thing with this car now of all the things that we've done on it on this once it's going it's just a rocket ship in other words not only have you got McLaren that is reliable you've got a really really fast one yeah I'm keeping it I'm keeping this I've had it 5 years now 13,000 Mi nearly I use it all the time it's great I love it well there you go he's not buying this new car now we going have a break test from 100 mph when we reach the line full emergency stop car that stops in the shortest distance winds I stamped on that as hard as I could we've both got air Braes we both got carbons which have been warmed up I think that's a tire difference definitely see it's a safety thing having cup twos as well it helps protect pedestrians once they're warmed up it's a shame you kind of like heaters in the wheel arches that can radiate heat on them to warm them up quicker yeah there's an idea there I might have to look into that anyway that was really interesting that car is quick there's not much difference between these two and another lesson Tire Choice makes a big difference not only accelerating and putting your power down but also stopping anyway I hope you enjoyed the video just want to say a huge thanks to the people that have lent me this car they've also got a YouTube channel huge thanks to Andy as well for bringing his 720 s along once again to perform brilliantly now if you want
