F80 M3 and F82 M4 chassis codes

Hi,

Why is the F80 M3 an F80 and not an F30, an why is the F82 M4 an F82 and not an F32?

Thank you!!

- Avi

Probably because the 4 series is the F32. So add 50 to each regular series to get it's M counterpart.

Because they are a whole other cars from their regular normal counter-parts...

They have wider track (wider is better Pontiac commercial)
their suspension and dynamics are different, making them significantly Not the same as the non-Ms. So technically now you cannot have an M3/4 just by swapping engines...

Obviously! But how come the M5 is still an F10?

Technically it's F10M. And going forward, M cars will have unique chassis designations.

Why is the new 3 coupe and M variant being called the 4 and M4?

Because BMW wants to.

Same goes for the chassis designation.

Its so simple:

F3x: regular Steel-Chassis/Car-Body
F8x: lighter reinforced Steel/Aluminum/Carbon-Composite(?)-Chassis/Car-Body

was debated here long before!
