The finish line is insight. The new BMW 4 Series Coupé has entered into the final phase of testing. The initial pre-production development has been carried out at race tracks and other test facilities around the world, and now concludes on the country roads and motorways surrounding the BMW Group’s Research and Innovation Centre in Munich for final touches.
Powered by a straight-six engine that delivers a maximum output of 374 hp, the range will be spearheaded by a BMW M model in the shape of the new BMW M440i xDrive Coupé, featuring 48V mild-hybrid technology for the first time. This will include a 48V starter-generator and a second battery employed to both ease the load and work in partnership with the engine. Besides improved efficiency, the main benefit here is punchier power when the driver hits the accelerator hard. The additional 11 hp generated by the electric boost translates to lightning-fast off-the-line getaways and in-gear sprints.
The phenomenal power generated by the engine in the new BMW M440i xDrive Coupé is channelled to the road via an eight-speed Steptronic Sport transmission and the car’s intelligent all-wheel-drive system. The M Sport differential is also on hand to make sure that drive power is deployed to optimum effect in demanding driving situations. The locking effect generated by an electric motor limits speed equalisation between the inside and outside rear wheel when cornering, thereby enhancing traction and handling stability while enabling the driver to power out of bends with considerable confidence
