IMO you are cutting BMW to much slack on weight if you resign to that 3300 lbs is not doable. A Porsche 991 has all the latest tech and safety equipment and weigh in at just over 3000 lbs. if BMW's main design focus is now weight reduction for the F80 and they have admitted increase of lightweight materials as plastics and CF I don't see why 3300 lbs is a stretch for the admittably bigger car but 3300 lbs is a bigger number than 3000 lbs. Weight increase is not linear to size increase since not all parts grow with the exterior like the engine, tranny, front seats, wheels, and electronics for example.

I have a feeling that the F80 can shave the 200 lbs from the ~ 3500 lbs F30 335i purely by replacing steel with alu in certain weight critical areas even with the added beef to areas as brakes etc. I don't think the F30 is especially big on alu.

I don't care much if the F80 produces 390 or 490 hp but I will be dissapointed if it's 3500 lbs instead of 3300 lbs.
