Our resident BMW man, Revvmaster has already spotted a new BMW 6 Series some months ago. That topic has been discussed here:
BMW 645 (PICS : BMW 6 Series spotted!)
I don't know about Business Standard Motoring, but, I clearly remember James May of BBC Top Gear saying that since it was a coupe, BMW wanted to make it a pure drivers' car. They had given it a much stiffer suspension setup compared to the 5 Series and shod it with "rock hard" run-flat tyres. That made the ride horrible.
