Neither do I want to get my hopes to high, not to be disapointed. But by looking at some facts, it is possible. M5 F10 (1945 kg) is 40 kg heavier than 550i F10 (1905 kg). Take into account that the 8 Speed AUT adds about 10-15 kg over 6MT, and 7 Speed DCT adds about 20-25 kg over 6MT. F80 chassis alone is said to be 30 kg lighter than F30 chassis. The 335i F30 is already at 1585 kg. The M3 F30 could easily get under 1550 kg. Now I don't know what other lightweight saving M3 will get, if it gets CF body panels, like the roof. It could happen the M3 F80 will not get all what is possible, on one hand to keep the price lower, and make the M4 F82 significantly (?) more sporty and justify the higher price. Sidenote: The low weight will be for the standard version, options can add significant weight.
