- German tuner G-Power offers a trio of performance upgrades for the BMW M4 CSL
- The highest option takes the twin-turbo 3.0-liter engine to 709 hp (529 kW / 720 PS).
- G-Power also offers carbon fiber body panels and forged wheels.
The BMW M4 CSL is the ultimate M4, as it’s lighter, more powerful, and boasts a sexy ducktail spoiler at the back. While the stock 543 hp (550 PS / 411 kW) sounds great, G-Power offers three levels of power upgrades for the M4 CSL, alongside carbon fiber components and forged wheels.
The tuner’s G4M CSL Bi-Turbo benefits from the same upgrades offered for the G3M CS Bi-Turbo, albeit in a sexier two-door bodystyle.

BMW M‘s twin-turbo 3.0-liter six-cylinder engine received new software and an upgraded exhaust. The range-topping GP-720 option delivers an impressive 709 hp (529 kW / 720 PS) and 850 Nm (627 lb-ft) of torque and raises the top speed limiter to 320 km/h (199 mph). In addition to the software, there’s a full “Deeptone” exhaust system which combines sport downpipes featuring high-flow 200-cell catalytic converters, with new center and rear mufflers.
Next in line is G-Power’s GP-670 option, which is good for 661 hp (493 kW / 670 PS) and 800 Nm (590 lb-ft) of torque. This option retains the factory downpipes but gets the center and rear exhaust mufflers, in addition to G-Power’s software.
Finally, the entry-level GP-620 is good for 612 hp (456 kW / 620 PS) and 750 Nm (553 lb-ft), all thanks to the tuner’s software and axle-back exhaust muffler. Independently of the package, G-Power’s BMW M4 CSL has two sets of tailpipes measuring 100 mm (3.9 inches) and 110 mm (4.3 inches) respectively.
G-Power
The visual modifications of G-Power’s G4M CSL Bi-Turbo are more subtle compared to Manhart’s MH4 GTR II. The Venturi carbon fiber hood and engine cover highlight the presence of a powerful engine, while the stock splitter can be combined with matching garnish for the bumper intakes. G Power also offers a set of decals, adding red touches around the bodywork.
The modified M4 CSL rides on a new set of forged wheels (Hurricane RR or Hurricane RS design), measuring 20 inches at the front and 21 inches at the rear. Depending on the owner’s preferences, interior updates can include carbon fiber shift paddles, velour floor mats, and new upholstery.
G-Power says that each upgrade is individually available for the BMW M4 CSL. Note that the model has a limited production of 1,000 units, meaning that the target group for the modifications is not as large as with the widely available M4 variants.
