Hi everyone,
The 650i xDrive (F13 and F06) can hit 60mph in 4.4 seconds. That is only 0.1 seconds slower than the M5 and 0.2 slower than the F13 M6 and F06 M6, according to the international BMW website.
My question is: Are these two very close to the M5 and M6s' performance on the track?
If so, the M division should consider weight loss for the M5 and M6s, obviously. Everyone already knows that they are porkers.
P.S.

~3.4 seconds from 0-60mph for the next E63 AMG. Watch out, M5.
