A bit disappointing, I was expecting a time under 8 mins on the Nürburgring. And I think the 645i has a very similar time on the Hockenheim circuit. Anyway, the acceleration isn't bad.
SportAuto:
Nordschleife: 8.13min
Hockenheim: 1.16,5min
0-100km/h: 4.5s
0-200km/h: 13.8s
On the track: EDC Sport is slower than Comfort.
Suspension is too comfortable.
Excellent result: 58 out of 80 points new method with wet handling.
Last sentence: "With the announcment, the M5 would combine the every day requirements with racing demands, the M-GmbH have claimed a bit too much."
WOW! Looks like they almost tried to copy Mercedes, straight-forward rocket. (not saying the M5 is slow, but I and many others expected much more)
