As we wait patiently for the official details of the all-new BMW M3 and M4, a few new details have risen to the surface thanks to a video released by BMW.

In the latest round of publicity videos by BMW, the new M3 features on the roads around the Nurburgring and then on the track itself. The interesting part is that the engineers interviewed note that the performance sedan will be available in both rear-wheel-drive and x-Drive (all-wheel-drive). Unfortunately, they didn't let slip on the power figures but by now we all seem to have settled on the same outputs as the current X3 M/X4 M. That's the 3.0-litre straight-six with 375 kW and 600 Nm, continuing the trend of more power and more torque for every generation, whether it needs it or not.

Further into the video above, the engineers gointo great detail about how each part of the Nurburgring circuit helps them develop individual areas of the car. Those who enjoy the technical side on vehicle engineering are in for a treat as they go through stability control, aero balance, braking stability as well as front end turn in and traction.

Expect to see a prototype drive of the new M3/M4 extremely soon on our site.For now, this leaked image of the rear end is the best image we have of the car without camouflage on.We expect the production version to be ready and shown to the public before the end of the year. SA introduction will likely be in 2021 although no firm date has been assigned yet.
