This September is when the brand new BMW M3 Sedan and BMW M4 Coupe will finally break cover. It's been a very long wait, but numerous spy shots of camouflaged models have helped ease the wait. Now, as development reaches the final stage, the camo is starting to come off. Our spy photographers have spotted another prototype of the BMW M4 Coupe cruising the streets with less camouflage disguising the design, exposing more of the front fascia.

If you were hoping the BMW 4 Series' massive kidney grille won't carry over to the M4, prepare to be disappointed. Love it or loathe it, BMW's controversial new design direction is also being applied to the BMW M4 and M3, so we're going to have to get used to this new look.

We also get a better look at the new M4's larger air intakes and lower front splitter that give it an angrier-looking face than its standard 4 Series sibling. Elsewhere, the production headlights and taillights are now fully visible, while the quad exhaust system suggests this is a near-final production prototype.

We still have a few months to wait for the new BMW M3 and M4 to be revealed, but BMW has already confirmed the technical specifications for the new performance sedan and coupe. Both models will be powered by the same twin-turbocharged 3.0-liter straight-six engine as the BMW X3 M and X4 M SUVs producing 480 hp in the base version and 510 hp in the range-topping Competition variant.

The former will be RWD and come with a purist-pleasing six-speed manual gearbox, while the latter will have an eight-speed automatic for faster lap times. BMW's M xDrive four-wheel-drive system will be offered for the M3 and Competition after they launch.

BMW hasn't confirmed when deliveries will start after the new M3 and M4 debut in September, but reports claim the RWD versions will arrive in early 2021 followed by the AWD Competition later the same year. After the M3 Sedan and M4 Coupe go on sale, they will later be joined by convertible and hot CS variants.
