Pending the arrival of the M6 version, which will get a 550bhp twin turbo version of the 650i's V8 and hopefully bring us out in a proper hot flush, we'll stick to reporting BMW's take on the 'regular' strength versions of its new coupe.
"It's the only car in the segment to offer the combination of top-class sporting ability, exclusive touring comfort and a 460-litre (16.24 cu. ft) luggage space," they say.
We wouldn't argue with the practicality and comfort aspects, having admired our old PH fleet (last generation) M6 for just such characteristics. And while we can't claim the standard versions of the new convertible massaged the PH mojo over-muchly, if the new M6 is half the machine the old one was, we're likely to be big, big fans.
But back to the regular coupe, and BMW's new pictures of same, as it's all we've got to work with for now. Prices remain TBC.
