Doubtful when BMW is too cheap to even use a CF roof. We'll be lucky if the 1M stays at 3400 lbs and doesn't gain another 50-100 lbs.
Best case scenario is a 3300 lb car with 360 hp which yields a power to weight ratio of 241 hp per metric ton (9.17 lbs/hp).
Most likely scenario is a 3400 lb car with 340 hp yielding a ratio of 221 hp per metric ton (10 lbs/hp).
Worst case scenario is a 3500 lb car with 340 hp yielding 214 hp per metric ton (10.3 lbs/hp).
For referrence:
e46 M3 = 216 hp/ton (10.2 lbs/hp)
e92 M3 = 247 hp/ton (8.94 lbs/hp)
e86 Z4 M = 231 hp/ton (9.54 lbs/hp)
135 tuned to 380 hp = 246 hp/ton (8.95 lbs/hp)
Of course power to weight is a little misleading. For a given ratio, a lighter car will handle and brake better. Not to mention feel much more tossable.
