The E46 M3: A Benchmark for the Ages
The original BMW M3, produced from 1998 to 2006, was a powerhouse on the road and track. With its 3.2-liter inline-six engine producing 333 horsepower, it was an impressive vehicle that quickly gained a following among driving enthusiasts. The E46 M3's impressive performance was also matched by its handling, which made it a joy to drive on twisty roads and tracks alike.
One of the key factors that contributed to the E46 M3's success was its rear-wheel drive layout, which allowed for precise control and agility. The car's limited top speed of 155 km/h (96 mph) also made it feel quick but relatively effortless, thanks in part to BMW's reputation for producing smooth and refined engines.
Despite being produced for six years, the E46 M3 was eventually surpassed by newer models from competitors like Mercedes and Audi, which offered more powerful engines. However, during its production run, the E46 M3 remained a fan favorite among driving enthusiasts, particularly those who appreciated the car's dynamic handling and rear-wheel drive layout.
In comparison to its successor, the G80 M3, the E46 M3 seems relatively modest by today's standards. The newer model boasts a 3.0-liter inline-six engine with two turbochargers, producing 510 horsepower - a significant increase over the E46's 333 horses. Additionally, the G80 is significantly larger and heavier than its predecessor, weighing in at 1730 kg (3824 lbs), compared to the E46's 1470 kg (3223 lbs).
Despite its size advantage, however, the G80 M3 still manages to deliver impressive performance, accelerating from 0-62 mph in under four seconds. This is a full second faster than the E46 M3 and a testament to the significant improvements in engine technology over the past two decades. Furthermore, the G80 has been fitted with an eight-speed ZF automatic transmission, which provides smooth and seamless shifting.
In terms of its driving experience, both the E46 M3 and G80 M3 are known for their exceptional handling and agility. However, the newer model is more likely to induce a sense of stress among drivers, particularly in wet conditions. The car's electronic stability control system can sometimes make it feel vague and unresponsive at the front wheels, which can be unsettling on faster sections of track.
To put these cars through their paces, we brought them together for a head-to-head shootout on a wet track. With traction control disabled and the rear differential locked, we set off to see how each car would perform under pressure. The G80 M3 quickly took an early lead, but it soon became apparent that driving in the wet was not its forte.
As we progressed through the lap, the E46 M3 began to close the gap, thanks to its more predictable and engaging handling on a track with plenty of corners. However, when it came to braking, the G80 M3 had a significant advantage, thanks to its carbon ceramic brakes, which provided exceptional stopping power.
Despite its superior performance, however, the E46 M3 still managed to eke out a respectable lap time - 1:36.7 seconds - and put up a valiant fight against its successor. However, when we compared the two cars side by side after completing multiple laps, it was clear that the G80 M3 had won the day, with a blistering time of 1:31.2 seconds.
So what has 20 years done to the BMW M3? For starters, the price tag has increased significantly, with the UK's entry-level competition model starting at £75,000 - a far cry from the E46's value-adjusted price of around £70,000. Additionally, while the E46 boasted a naturally aspirated engine, its successor has been fitted with two turbochargers, producing a significant increase in power.
In terms of size and weight, however, the G80 M3 is a different beast altogether. With a longer wheelbase and wider track, it's clear that BMW has prioritized comfort and practicality over outright performance. This is reflected in its substantial weight - 1730 kg (3824 lbs) compared to the E46's 1470 kg (3223 lbs).
Despite these sizeable differences, however, the G80 M3 still manages to deliver impressive acceleration, thanks to its powerful engine and advanced transmission technology. And while driving it on a wet track may not be an ideal experience for enthusiasts, it's clear that BMW has done an excellent job of leveraging technology like adaptive dampers to disguise the car's size and weight.
Ultimately, however, the G80 M3 feels heavy, albeit in a comfortable and refined way. While it's undoubtedly faster than its predecessor, there's still a sense that it's lacking something - perhaps a more engaging driving experience or better handling on wet roads. As we concluded our shootout, one thing was clear: while the E46 M3 may have been a benchmark for its time, the G80 M3 is an altogether different beast - and one that will likely leave many enthusiasts wondering what BMW has done to make it so much faster, yet also more comfortable and practical.
