I've said it in the pas and I'll say it again, M3 has gobs of torque, and it has it everywhere. If you disagree, answer me this, if the M3 is both heavier and has less torque than a 335i, how does it out accelerate it (stock for stock)???
M5 = 1st: 3.99; Final: 3.62; Crank Tq @ 3.5K: 260 (HUGE caveat: likely not a first gear pull)
3.99*3.62*260 = 3,755

M5 Crank Tq taken from the dragtimes: http://www.dragtimes.com/2006-BMW-M5...aphs-9623.html

Result @ 3.5K in first gear: M3 Wheel Tq = 5,500; M5 Wheel Tq = 3,755
M3 wins!
