OK diving in to my predictions, at least many of them. These are based on tons of spreadsheeting competitors, using a bit of physics based formulas and just looking at what competitors need to be beaten.
-0-60 mph: 4.1 s (not the brochure number, they always underrate)
-1/4 mi: 12.6 s
-Nurburgring Nordschleife lap time: 7:57 m:s
-Lateral g’s on skidpad: .90 g
-Braking 60 mph - 0: 110 ft
-100 mph - 0: 195 ft
-Top speed: 190 mph (limiter removed, obviously)
-HP: 433 bhp (brochure number)
-Torque: 330 ft-lb
-Redline: 8500 rpm
-SMG 7 speed (with shorter gears than E60 M5)
-Weight: 3500 lb (with significant aluminum/composites)
-Wheel/tire size 275/35-19 rear
-Base price: $57,500 USD
Specifically on the 0-60... E46 M3 did really well compared to others in this class despite pretty bad lb/hp and lb/tq figures. It did it with quite low gears. BMW can tune the the 0-60 pretty precisely and it should be just as fast if not faster than the E60 M5.
If you really want to see how clever you are post your reply. It will be fun to look back and see how we did!
