[Video] How much faster can the BMW M3 xDrive become after tuning?

Often we do not know how much faster a car really is after an upgrade unless the tuner explains the details. In this video, Carwow tries to show exactly how big the difference can be between two M3 models with different performances.

Two xDrive BMW M3 Competitions were tested with one getting tuned, while the other is not. The tuned variant produces 600 hp and 750 Nm (590 lb-ft) of torque. Nowadays, V8 BMWs like the M5, M8 and X5/X6 M, which are not in competition, achieve this output. The M3 is lighter than other cars, so it should be faster.

ECU remaps are usually used for the Stage 1 upgrade, which requires no hardware modification. The other car taking part in this race is a standard BMW M3 Competition. At first glance, however, it does not appear to be a bad driver. The 3.0-litre in-line six-cylinder engine of the standard M3 delivers 510 hp and 650 Newton metres of torque to the rear wheels. Each vehicle is equipped with an eight-speed automatic transmission from ZF, which is a fantastic feature.
