DO NEVER EVER SAY THAT BMW M3 WILL BE FASTER THAN AUDI RS4, CHECK THIS: Some crucial numbers
Although we expect the 2008 BMW M3 will weigh slightly more than the former 3,460-pound M3, the additional 81 hp represented by the new 4.0-liter V8 should yield improved performance. There won't be anything official for quite some time, but we hear BMW expects acceleration to 62 mph in 4.9 seconds. Top speed will be electronically limited to 155 mph as with existing M-cars, but we understand the car is geared for 175 mph at the V8's redline in 6th gear.
4.9s fo M3...4.1s for RS4...BRAVO:d
