BMW’s stuck an M badge on its 7-Series, gifting the luxury flagship sedan immense straight-line performance.

The M760Li xDrive, as it will be known, now gives BMW a weapon to fight Audi’s S8 and Mercedes-AMG S63, while also injecting a V12 variant into the new 7 Series range.

BMW’s lowered a 6.6-litre V12 into the long wheelbase sedan. Relying on two turbochargers it musters 441kW at 5500rpm and a huge 800Nm at 1500rpm.

More firepower costs the M760Li at the weighbridge, as the heavier V12 means it tips in at almost 2.2-tonne. So to keep its mass in check, BMW’s teamed its air suspension with active roll technology, a more direct steering ratio, stickier tyres, and dinner plate sized brakes.
