So, how can the M3, which weighs 500+ lbs more (3648 lbs ouch) get to 0 to 60 in 4.1?
Defies logic. Maybe, R&T hit a worm hole?
e92 M3 = 4.6 seconds.
All cars will demonstrate a range when all variables are not precisely controlled. Look at the "database" we have put together here
Minimum time is 4.1 s it has been repeated with the Coupe and Sedan. Worst time is 4.7 s. Average is about 4.3 s. Will you or I consistently get 4.3 s? Almost for sure not, however your figure is very conservative. Most folks when quoting numbers pick the best one, I like to show off that number as well but having a range is the best information you can have. BMW quotes 4.7 s and they are very conservative, most decent drivers should be able to get this figure. Again this means your figure is simply in the range but not close to the average nor anywhere near the best reported figures.
By the way the GT3 will have a range as well and I have seen 3.9 s quoted many times for the 2007 GT3. No major inconsistencies there.
Last but not least looking at 0-100, 1/4 mi times and traps are better indicators of a cars performance and it power to weight. 0-60 is too much a test of chassis, traction, tires, launch technique, etc.
