Tuned BMW M4 CSL Packs 702 HP And Wears An 18-Piece Body Kit

Listen to this article

Manhart gets ahold of the BMW M4 CSL and turns it into the MH4 GTR II. The 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 stock output is 543 hp (404 kW) and 479 lb-ft (649 Nm).

To achieve such significant gains, Manhart fits its MHtronik auxiliary control unit and a stainless steel exhaust that ends in four round pipes that each measure 4.3 inches (110 millimeters). Buyers can select a 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 rides on 20-inch Forged+ 1 wheels from Yido Performance. They have a 15-spoke design, and customers can pick the finish. 

Manhart installs an 18-piece, carbon-fiber body kit to the M4 CSL. The parts include a large front splitter and canards on the nose's outer corners. 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 don't have TÜV approval for use in Germany, so they are for export customers only.

BMW debuted the M4 CSL in May 2022 at the Goodwood Festival of Speed. It's the quickest series-production model ever from the brand around the Nürburgring Nordschleife with a time of 7 minutes and 20.2 seconds.

BMW puts the M4 CSL on an extensive weight loss program. This includes making extensive use of carbon-fiber-reinforced plastic components, including the hood, roof, and trunk lid. The standard M Carbon ceramic brakes shed 31.5 pounds (14.29 kilograms) over conventional stoppers.

BMW is making just 1,000 examples of the M4 CSL. In the United States, the model starts at $140,895 (including the $995 destination charge).
