HEY, want to know how fast the BMW M6 Gran Coupe leaps from rest to 100km/h?

I’m not telling. That’s because acceleration times are not that important, according the architects behind the fastest BMW badges around.

After all, the luxury car-maker asks, how many times do you need to use that intantaneous burst of standing speed from the twin-turbo 4.4-litre V8 on the famous Nurburgring, that 21-kilometre snaking strip of tortured German bitumen that remains today as the standard measure of an M-badged car?

“Only once, when you start,” said Jorg Bartels, the head of sales operations management for Munich-based BMW M, who was in Australia this week to introduce the four-door 6 Series. “Then it is all about corner speed.”

Don’t expect the $299,500 four-door coupe, then, to be a benchmark-setting performance hero. For that, save yourself $70,000-odd, buy a bog-standard M5 and be happy.
