At the international launch of the new BMW M3 and M4, The Correspondent, Matt Davis, connected with Albert Biermann, VP Engineering BMW M, to discuss the long list of improvements to the drivetrain and powertrain that result in the new M3 and M4 being praised by most journalists.

The aero downforce and cooling traits of the underbelly have both been enhanced. We noticed particularly the standard locking rear differential and its enormous cooling vanes. This differential needs to work harder than ever as there is now a drift sensor which senses drift and immediately locks things up.

The front and rear (especially rear) axle carriers are now bolted directly to the chassis and not via dense rubber bushings anymore. Hence the added ties to the motorsports world, among other details of course.
