BMW has released a fresh teaser image (and shots of camouflaged prototypes testing) previewing its new M3 and M4, while also confirming the peak power outputs of both the standard and Competition variants.

Scheduled to be fully revealed in mid-September 2020, the Munich-based firm’s high-performance G80-generation M3 sedan and G82-generation M4 coupé will boast what BMW describes as a “significant increase in performance” versus their predecessor models.

The Bavarian brand has confirmed the standard models will be offered with a twin-turbo 3,0-litre straight-six petrol engine delivering 353 kW via a six-speed manual gearbox. The Competition derivatives, meanwhile, will make 375 kW (like the X3 M Competition and X4 M Competition) and be mated with an eight-speed M Steptronic transmission.

“For customers who prefer a puristic performance experience and particularly intense interaction with their vehicle, the model variants with a manual transmission constitute an offer that is unique in this segment,” said Dirk Häcker, head of Development M Automobiles and BMW Individual.

“On the other hand, with the Competition versions of the new BMW M3 sedan and new BMW M4 coupé, we are addressing maximum dynamics in regards power development and transfer – initially with classic rear-wheel drive and, at a later date, also in conjunction with the latest version of our four-wheel drive system M xDrive,” he confirmed.

BMW promises “comprehensive innovations” in the areas of drive, suspension, springs, dampers and braking technology for the new M3 and M4.

Question is, will the M3 adopt an interpretation of BMW’s divisive new grille (which we’ve already seen in a leaked image of the new M4 as well as in the teaser image above)?
