Lucky Punch, not more. Other cars are even better.
BMW switched to always by the models but no car is a really racecar.
The e46 gt3 it wasn't, the e92 m3 gt3 it wasn't, the z4gt3 it wasn't and the m6 it wasn't too...
I think the best Setup from the BMW Portfolio is a i8 combinated with the legendary v10 engine and an hybrid System like KERS. That would be revolutionary.
Why can not BMW finally construct a real racecar like a Audi r8 lms?
