Whoa - that's plenty quick acceleration for such a heavy vehicle. I wonder how it does on the twisties and even the track, compared to let's say a Mustang GT or Camaro SS?
Why on earth would you want to drive a 6 series on a track ?
But I'm pretty sure a 6 series would make mince meat of a Mustang or Camaro on twisty roads in the Alps.
Or rather, the drivers would make mince meat of themselves hitting a wall while trying to catch up with the BMW.
Well, maybe not but you started being silly.
A 6 series is a fast car by any standard but not intended for racing. BMW already made the M3 for that and I've heard it's pretty good at it. It would be weird if BMW tried to out compete all of their own cars. That's a race they're going to lose either way you look at it.
