So much bs speculation lmao, but hey I guess that's why people have forums lol...
I'd be happy to see 415hp/395trq and at the targeted weight. The at would be an absolute beast easily putting down a low 12s pass on the 1/4.
On the other hand it's likely more realistic that hp to wheels will be a little higher than current M3, but that weight will be a max of 100lbs lost.
They'd literally have to make half the cars parts in CF to shave 300lbs. Doors, panels, fenders, hood, roof and trunk. What they should focus on for the future is the frame of the vehicle and making the majority of construction in CF.
Alas, I can't afford a $90k sticker anyways haha. So this is all a dream for me only to be made reality when the car is used and in the market for 3-4yrs.
