This is the BMW M6 Gran Coupe

Last month, BMW teased a shady, sinister-looking M-Power version of its 6-Series Gran Coupe. Today, it has given us both barrels straight to the chest. Internet: meet the M6 Gran Coupe.

As we suspected, it sports very similar firepower to its ‘standard' BMW M5 and M6 brethren. And by very similar, we mean identical: underneath that rather lovely body sits a 4.4-litre, twin-turbocharged V8 petrol engine developing 552bhp and 502lb ft of torque.

As such, it will accelerate from 0-62mph in just 4.2 seconds - exactly the same as the M6 Coupe and 0.1s quicker than the M5 - and run on to a limited top speed of 155mph. If you so wish - and you live in Germany or own substantial acres of awesomely paved, straight runway - you can have the limiter set to 189mph with the M Driver's pack.

That power is sent to the rear wheels via a seven-speed double clutch M gearbox, featuring Launch Control (which is ace), and something called low speed assistance. We doubt with 552 horses under the bonnet, this will ever be an issue.

There's an electronic limited-slip diff at the back in collusion with the DSC stability control, both of which distribute the engine's power to give you maximum traction when a sudden burst of B-road rage descends. There's also a hydraulic steering rack (surely a good thing), optional carbon ceramic brakes, and dynamic damper control to better tailor the chassis.

Outside, it's familiar M fare, with those large air intakes sitting underneath the M kidney grille, flared wheelarches - pointing to a wider track both front and rear for the M6 Gran Coupe - 20in alloys, a new rear apron and of course, M-Power's favoured quartet of exhaust pipes at the back. Oh, and that rear apron incorporates a CFRP diffuser too, helping direct the airflow underneath the Gran Coupe.

It costs €128,000 in Germany, which is around £103,000, which is around £10k more than a BMW M6 Coupe. Do you, as BMW implores, agree that it brings "luxury and aesthetic appeal" to the M6 range? Tell us below.
