The new BMW M3 Sedan and new BMW M4 Coupe also feature a CFRP propeller shaft with high rigidity and low weight. It is a single-piece component, without a center bearing, but still delivering more dynamic powertrain response.
The properties of the extremely light yet impressively durable material CFRP have allowed the engineers to follow a fundamentally new approach in the manufacture of the drive shaft. Made from CFRP, this component feeds the engine’s torque from the gearbox to the rear differential and works under extremely heavy loads – especially in high-performance vehicles.
So just how strong is the new BMW M3 Sedan and new BMW M4 Coupe’s CFRP drive shaft? Take a peek at its engineering testing!
