Manhart, a German tuner, has taken the BMW M3 Touring and transformed it into a powerful wagon that now generates 641 horsepower and 590 pound-feet (800 Newton-meters) of torque. This is a significant upgrade over the original stock output of 503 hp and 479 lb-ft.

The increase in power is mainly achieved through the implementation of Manhart’s MHtronik control unit. Additionally, the exhaust system has been completely revamped, with Manhart opting for Remus components and incorporating HJS sport downpipes.
