The car, now testing on public roads in development form and due to go on sale in 2020, would inherit the active technology from the 5 Series and 7 Series. If the hardware does make the cut and is fitted to the super-saloon, the M3 would be the only car in the upcoming 3 Series range (due later this year) to feature it.
BMW's upcoming Mercedes-AMG C63 rival can use the active steering technology because it's built on BMW’s latest CLAR structure. This platform uses more aluminium and high-strength steel to save weight and improve chassis rigidity.
CLAR already underpins the 5 Series and 7 Series, as well as M division models, and in the M3 it will be accompanied by extra carbonfibre parts, the largest of which will be an all-carbon roof. BMW has ruled out using a carbon core, like in the 7 Series, in the next 3 Series models, due to the complexity of the production process and significantly higher demand for the smaller saloon. But the new car is still pipped to weigh less than the recently revealed 1585kg M3 CS.
The use of more exotic materials will enable the weight loss despite a small growth for the M3, with an expected 20mm growth in wheelbase and 60mm expansion in total length. It's understood that BMW isn't interested in offering a part-time four-wheel-drive system like the one used on the new M5, largely due to the weight penalty it would bring.
