With September 23 just around the corner, BMW has released another set of smoky teasers aimed at revealing some of the key features of the upcoming BMW M3 and M4.

While the G20 3 Series was a good car in its own right, for enthusiasts, much of the focus has been on the rather fantastic M340i model and was essentially the closest thing to an M3 at the time. In fact, it's only been relatively recently when BMW finally said that an M3 and M4 were coming, including a brilliant touring (estate) version.

It certainly didn't help that the rather divisive kidney grille to centre stage during the leaks and rumours. But, as with all BMW M cars, we can expect some brilliant performance, regardless of that grille. Right away, we have a very good shot of the new BMW kidney grille despite all of that smoke, and since it's an M car, we can expect a blacked-out treatment with subtle badging.

The new M3 and M4 are expected to come in new colours, and this Isle of Man Green looks pretty amazing and will definitely turn heads. Next up, we get a glimpse of the gear lever in all of its six-speed manual glory; a refreshing and welcome sight with all of the automatic transmission options going around.

We also get a glimpse at the new seats in the BMW M4, donning the illuminated M4 logo and reworked shoulder bolsters and contrast piping. Fixed headrests and seatbelt pass-throughs are a highlight here. We like them, and we're pretty sure that they'll have all the adjustments needed to get the best seating position for all that manual shifting goodness.

Lastly, we see a shot of the rear of the M3, with a neat boot lip and reworked rear diffuser, and an actual quad exhaust pipes.

Expect power to come from a familiar 3.0-litre twin-turbo in-line six with 473 bhp (353 kilowatts) while the upgraded Competition model will get 503 bhp (375 kW). The Competition model is going to be limited to an automatic, however, guess you can't have it all. Expect the M3 and M4 to arrive in the United Kingdom next year.
