The head of BMW’s M division says the upcoming M3 and M4 will boast the “most powerful” engines in their segments.

Speaking to CarAdvice, BMW M CEO Markus Flasch revealed the new models were set to hit showrooms only in 2021.

“So 2021 will be the year of the BMW M3 and M4,” Flasch told the publication.

“There’s not so much I can disclose about the models but you can expect that we will have the most powerful engine in the segment,” he added.

Of course, the V8-powered Mercedes-AMG C63 S generates 375 kW in both sedan and coupé form, while Alfa Romeo’s Giulia Quadrifoglio offers the same peak power output from its V6.

Flasch’s comments suggest the rumoured Competition versions of the new M3 and M4 will boast more than the 375 kW churned out by the twin-turbo 3,0-litre inline-six used in the X3 M Competition and X4 M Competition.

He also confirmed manual variants have been developed, alongside with rear-driven and all-paw models.

"It will have a manual stick shift, all-wheel drive and rear-wheel drive. You can expect we will do derivatives and special models based on this, because this [the 3 Series range] is what BMW was founded on.”
