Also keep in mind that the RR P-cars have much better traction off the line than any FR, including the M3. The M3's ET will be much closer to the Carrera S (though it'll trap faster) than the GT3, despite the power/weight ratios.

according to the BMW pdf press releases the ///M3 waighs in @ 3483lbs not the 36xx lbs noted above. you can download the US/English pdf on bmwusa website. thats the official weight if anyone says otherwise its not off fact but their own opinion. trust the manufacturer not the opinion of others ;-)

For the GT3 I was using the actual weighed curb weight by Motor Trend (NOT test weight). This includes base curb weight plus whatever options that particular GT3 came with. I am sure that the M3 the car mags get ahold of will weight somewhat more than 3483, since it will undoubtedly have some options. I am, honestly, surprised that Porsche lists the GT3 Curb weight at 3075 lbs on their USA web site. Both Car and Driver and Motor trend have it at 3235-3045 in their recent articles. Perhaps Porsche's definition of "Curb weight" is different than the norm (i.e. no liquids at all). 160--170 lbs is a BIG difference. Example 2: The Cayman S Curb weight is listed at 2954 lbs for manual transmission. Road and Track Aug 06 has their Cayman S curb weight at 3130 lbs! Another 176 lb "error?" I think Porsche grossly underestimates their curb weights for marketing purposes. For reference, the BMW 335i Sedan curb weight is listed at 3591 lbs and C&D test car curbed at 3635, so only 44 lbs off. This could be accounted for by the heavier 18" wheels of the sport package and extra power in the seats alone. So with normal stuff on it the M3 will probably weight about 3525 lbs, or 300 lbs more than a GT3 -- not bad!

E39 M5 engine
Hey T-Bone. Is this sw free? Where can I get it? In the meantime how about an interesting request? Run the new M3 with the old M5 engine. I read some good threads on how this hypothetical vehicle might perform. I guess it may only be fair to run it with the gear ratios and tire sizes from the M5 as well. The argument in that thread was basically the classic torque vs. hp argument. Thanks!

In my experience, those who suffer from HP always mention torque.... 414 hp is 414 hp, it is a measure of the work this engine can do. I encourage you to play with the software, all variables are adjustable. There is a free trial version.... www.cartest2000.com
