BMW has filed a fresh application to trademark the M7 badge in the United States, reviving rumours that the Munich-based automaker has plans to offer a full-fat, M-badged performance model positioned above the M760Li.

The folks over at Bimmerfest uncovered BMW’s latest application with the United States Patent and Trademark Office, which was made at the end of April 2018.

Interestingly, BMW had already trademarked the M7 badge in the US (way back in 2012, in fact), but oddly allowed the rights to lapse earlier in April. And this latest application seeks to fix that.

Of course, the brand’s application to trademark the badge by no means guarantees that it actually has plans to build an M7. But if a new flagship 7 Series is on the cards, BMW certainly has a couple of viable options in terms of powerplants.

Indeed, the 6,6-litre V12 powering the M760Li (which interestingly is rumoured to be nearing the end of its life) already makes a whopping 448 kW and 800 N.m, giving the hefty limousine a claimed 0-100 km/h sprint time of just 3,7 seconds.

Then there's BMW’s twin-turbo 4,4-litre V8, which churns out 441 kW and 750 N.m in the M5 (and apparently even more in the M5 Competition Package). A fettled version of the latter likewise seems set to power the upcoming M8.
