The folks over at AutoGuide sure do keep a close eye on trademark filings. Yes, after recently unearthing some intriguing information on possible upcoming Mercedes-AMG models, the US publication has now revealed that BMW has filed to register three new M Performance badges.

According to AutoGuide, the Munich-based automaker has applied to register the M335, M650 and M750 names with the United States Patent and Trademark Office. All three filings were made on June 20.

This, of course, suggests that the Bavarian brand has plans to expand its M Performance line-up (perhaps in response to Mercedes-AMG doing something similar with its 43-badged wares), offering buyers more options in the tier below the full-fat M range, along existing derivatives such as the M140i, M240i and M760Li.

If the M335 badge does indeed find its way onto the rump of a production model, chances are it’ll be only once the next-generation 3 Series (G20) debuts in 2019, as the publication points out.

And the M650 and M750? Well, AutoGuide speculates that these potential new performance variants in the 6 and 7 Series ranges could end up following the recently revealed M850i xDrive’s example, combining a twin-turbo 4,4-litre V8 with the brand’s xDrive all-wheel-drive system.
