Head to head in this sprint to 250 km/h test is the E46 M3 and the E92 335i in a speed comparison that reveal just how closely they perform against each other.
The M3 used for the test has been moded a bit with Supersprint Race Lightweight Exhaust Section 3, and CSL SMG software, but has 1 passager and full tank. The BMW 335i on the other hand is stock, has a small mileage, a bit of fuel and only driver on board.
Even so, it is a very interesting comparrison, because there is much debate on this subject – Which car is faster, a naturally aspirated M3 or twin-turbo powered 335i?
