Manhart takes the BMW M4 CSL and transforms it into the MH4 GTR II. Powertrain tuning pushes the twin-turbo 3.0-liter inline-six engine to an impressive 702 horsepower (524 kilowatts) and 649 pound-feet (880 Newton-meters). For comparison, the model’s standard output is 543 hp (404 kW) and 479 lb-ft (649 Nm).
To achieve such large gains, Manhart installs its MHtronik auxiliary control unit and a stainless steel exhaust that ends in four round pipes each measuring 4.3 inches (110 millimeters). Buyers can choose carbon or ceramic coating for them.

The MH4 GTR II also has a more aggressive stance. The suspension gets height-adjustable parts from H&R. It rolls on 20-inch Forged +1 wheels from Yido Performance. They have a 15 spoke design and customers can choose the finish.
Manhart installs an 18-piece carbon fiber body kit on the M4 CSL. Parts include a large front splitter and canards on the outer corners of the nose. The side sills extend outward from the body. The tail gains a prominent spoiler on the trunk lid. The diffuser surrounds the prominent exhaust tips.
The interior gains a roll cage and Schroth four-point racing harnesses attach to it. The company includes a helmet with the car.
Manhart also offers downpipes without catalytic converters or with 300-cell catalytic converters. However, these parts do not have TÜV approval for use in Germany, so they are reserved for export customers.
BMW launched the M4 CSL in May 2022 at the Goodwood Festival of Speed. It is the fastest production model ever produced by the brand around the Nordschleife of the Nürburgring with a time of 7 minutes and 20.2 seconds.
BMW is putting the M4 CSL on an extensive weight loss program. This includes the extensive use of carbon fiber reinforced plastic components, including the hood, roof and trunk lid. Standard M Carbon ceramic brakes shed 31.5 pounds (14.29 kilograms) over conventional plugs.
BMW only manufactures 1,000 copies of the M4 CSL. In the US, the model starts at $140,895 (including $995 destination charge).
