According to Khabar Khodro, the all-new BMW M4 appears to have been leaked in a social media post ahead of its official reveal later this year.
The image, first posted on Reddit from what looks like a BMW facility, shows the model's front-end look without disguise for the first time.
The M4's grille appears to be even more prominient than that of the new 2020 4 Series on which its based, thanks to black detailing. It's also flanked by new lower intakes, as is typical with M models. BMW claims the new grille design is inspired by that of the iconic 328 sports car from the 1930s.
Previous spy shots showed the new generation of Munich's sports coupé with limited disguise, with bulky rear wheel arches that afford a more muscular stance, and a swooping rear deck like that of the brand's flagship M8. Differences between this and the standard 4 Series are familiar, with the return of bigger intakes and quad exhaust tailpipes.
We already know that the new BMW M3 and M4 will receive a significantly upgraded six-cylinder engine producing more than 500bhp in its top form.
The flagship model to use this new engine will be a new M4 Gran Coupé (imagined by Autocar below), the first time the four-door coupé has featured a full-fat M variant. The coupé and convertible will also return beside the M3 saloon.
The 3.0-litre powerplant, which carries the internal codename S58, is a development of the firm’s standard B58 unit, as used in the existing 440i and other BMW models.
But as M division officials have revealed to Autocar, "it is for all intents and purposes an all-new drivetrain with significant changes to the base engine that allow it to rev beyond 7000rpm and deliver a much higher specific output” than today’s S55 engine.
