A few months before their world premiere mid-September 2020, the dynamic potential of the new BMW M3 Sedan and the new BMW M4 Coupé is already clearly perceptible

The BMW M GmbH is currently preparing the generation change for the iconic sports cars. With driving dynamics tests performed under racetrack conditions, the series development process for the new BMW M3 Sedan and new BMW M4 Coupé is entering its crucial phase. With a significant increase in performance vs. the predecessor models and an M-specific suspension setup, newly developed straight six-cylinder engines once again set benchmarks in the segment of high-performance sedans and coupés of the premium midrange class.

Traditionally, the Nordschleife of the Nürburgring sets the yardstick for the perfect interaction between drive and suspension technology in every situation

Traditionally, the Nordschleife of the Nürburgring sets the yardstick for the perfect interaction between drive and suspension technology in every situation. However, because the performance characteristics of a BMW M automobile have to convince not only there but also on the most varied racetrack profiles, the test engineers always expand the test programme to include further circuits such as the current test drives with camouflaged prototypes of the new BMW M3 Sedan and new BMW M4 Coupé at the Sachsenring.

The balance between superior performance and unrestricted everyday suitability so typical of an M attains a new level

Inspiring agility, outstanding dynamics and precisely controllable handling even in extreme sporting situations characterize their driving behaviour. The balance between superior performance and unrestricted everyday suitability so typical of an M attains a new level. “With each BMW M automobile, we put motorsport technology on the road,” says Markus Flasch, chairman of the board of the BMW M GmbH. “The new BMW M3 Sedan and the new BMW M4 Coupé embody this principle in a particularly intensive way, because both models stand unmistakably in the tradition of the most successful touring car worldwide. And results of the test drives show us that the new model generation is significantly superior to that of its predecessors in terms of performance.”

Besides a 475bhp variant with a six-speed manual shift, there is also the choice of a Competition model with 500bhp and an eight-speed M Steptronic transmission with Drivelogic

Like all current high-performance-automobiles from the BMW M GmbH, the new BMW M3 Sedan and new BMW M4 Coupé are offered in two performance levels: Besides a 475bhp variant with a six-speed manual shift, there is also the choice of a Competition model with 500bhp and an eight-speed M Steptronic transmission with Drivelogic. “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,” explains 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.”

Compared with the predecessor models, the straight six-cylinder engines featured by the new high-performance sports cars deliver a maximum output increase of 49bhp and 60bhp (Competition models) and a maximum torque of up to 650 Nm. Moreover, thanks to M TwinPower Turbo technology and high-revving concept, the power plant impresses with performance characteristics derived from motor racing.
