Manhart got the BMW M4 CSL and converted it into the MH4 GTR II. Powertrain tweaks pushed the twin-turbo 3.0-liter inline-six to an impressive 702 horsepower (524 kilowatts) and 649 pound-feet (880 Newton-meters). For comparison, the model’s stock output is 543 hp (404 kW) and 479 lb-ft (649 Nm).
To achieve these significant advantages, Manhart installed an additional MHtronik control unit and stainless steel exhaust ending with four round pipes each 4.3 inches (110 millimeters) in diameter. Buyers can choose carbon or ceramic coating for them.
