There’s a new high-pressure injection system and the double VANOS variable camshaft timing has also been recalibrated, resulting in a peak engine output of 601bhp produced at 5500rpm, and 590lb ft of torque seemingly arriving in an instant at 1550rpm and remaining as flat as a pint of night club lager until 5500rpm.
The basis for the M760Li’s extreme performance is a heavily reworked version of BMW’s twin-turbocharged 6.6-litre V12 direct injection petrol engine – the N74 as it is known internally. With modified turbochargers and a new fuel injection system that operates at up to 200bar of pressure among a myriad of other changes, it delivers 601bhp at 5500rpm together with a stout 590lb ft from just 1550rpm.
Now the second point. Why would BMW build such a car? One. Because they can and that’s important to show since many have challenged its reputation as “The Ultimate Driving Machine.” And two, to compete in that niche segment at the top of the high-end limousines where the likes of Audi and Mercedes-Benz have been playing in for years.
Overall, the M760Li xDrive has achieved its goals – it has an M DNA, it’s fast, it’s luxurious and allows for bragging rights – but in the end, in this segment, the purchasing decision making comes down to personal preferences and allegiances to one brand or the other.
