Here’s a very interesting comparison of the Porsche 911 GT3 RS against the BMW M3 GTS. Enjoy!
The GTS is not only larger, but also more difficult to handle. The car offers 450 horsepower at 1538 kg curb weight (factory claim 1530 kg), while the Porsche with the same 450 horsepower only weighs 1400 kg (1370 factory specification). Whether during acceleration, braking or cornering, the German editor continues to point out the higher weight of the GTS.
Performance wise, the Porsche accelerates from standstill to 100 km/hr in 3.7 seconds, while the M3 GTS stops the clock at 4.6 seconds. The gap becomes wider at 200 km/hr where the Porsche is 2.0 seconds faster.
