M6 is the special one

Some may question the purpose of the BMW M6 Gran Coupe but, upon careful consideration, it’s a car that makes the M6 Coupe seem virtually redundant and the M5 saloon seem staid.

BMW’s finest four door? That’s about the size of it.

The engine shouldn’t come as any great surprise to you. Yes, it’s the same 552bhp twin-turbocharged 4.4-litre V8 that’s found in the M5 saloon which unsurprisingly endows this four-door M6 with utterly searing straight line speed. Despite tipping the scales at 5kg heavier than the M5, the M6 Gran Coupe is actually slightly quicker, getting to 62mph in 4.2 seconds before running on to an electronically limited top end of 155mph. Opt for the driver’s package and this is extended to 190mph. This is an engine with an almost turbine-like power delivery, and while it lacks the aural charisma of the old 5.0-litre V10, it more than makes up for that with its extravagant torque - some 680Nm at just 1,500rpm.

BMW has tuned the ride quality to be a fraction more yielding than the rather firm M5 saloon and you can switch it into comfort mode if you’re just looking to waft along. The engine note might be a little insistent to put this in the top league of the most relaxing luxury saloons but this remains an M car and therefore has a requirement to steer accurately, offer taut body control through corners, deliver nuanced driver feedback, and, thanks to the fitment of an electronically operated M-differential, deliver excellent for such a potent rear-wheel-drive sports car.

For a car that’s over five metres long, the M6 Gran Coupe disguises its bulk extremely well. The carbon fibre roof stands out a bit better with paler colours and this is a vehicle that seems somewhat colour sensitive, but it’s striking, sleek and possesses so much more sense of occasion than either the M6 Coupe or the M5 saloon. Nobody I spoke to could quite define why this car has a charisma that’s slightly absent in the others but it has. It’s palpable.

Anything that can make the outlay of nearly £100,000 seem a reasonable course of action needs to be something special. The M6 Gran Coupe does and is.
