G-Power’s 709-horsepower BMW M4 CSL is ready for supercar hunting

If you think your M4 CSL isn’t special enough, G-Power’s visual and performance upgrades can satisfy your needs.

The BMW M4 CSL is the ultimate M4, as it is lighter, more powerful, and features a sexy ducktail spoiler at the rear. While the stock 543 hp (550 PS / 411 kW) sounds great, G-Power offers three levels of power upgrades for the M4 CSL, as well as carbon fiber parts 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 body style.

The twin-turbo 3.0-liter six-cylinder engine from BMW M has been equipped with new software and an upgraded exhaust. The top-of-the-range 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 to 320 km/h (199 mph). In addition to the software, there is a complete “Deeptone” exhaust system that combines a sports downpipe with a high-flow 200-element catalytic converter as well as new center and rear mufflers.

Next up is G-Power’s GP-670 option, with 661 hp (493 kW / 670 PS) and 800 Nm (590 lb-ft) of torque. This option retains the factory downpipe but features center and rear exhaust mufflers, as well as G-Power’s software.

Finally, the entry-level GP-620 develops 612 hp (456 kW / 620 PS) and 750 Nm (553 lb-ft) of torque, thanks to the tuner’s software and a rear-axle exhaust muffler. In addition to the kit, G-Power’s BMW M4 CSL is equipped with two sets of exhaust pipes measuring 100 mm (3.9 in) and 110 mm (4.3 in) respectively.

G-Power’s G4M CSL Bi-Turbo’s exterior enhancements are more subtle than those of Manhart’s MH4 GTR II. The Venturi carbon fiber hood and engine cover emphasize the presence of the powerful engine, while the splitter can be combined with matching trim on the bumper air intakes. G Power also offers a set of decals that add red accents around the body.

The modified M4 CSL is equipped with 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, velvet floor mats and new interior trim.

G-Power says each upgrade is available individually for the BMW M4 CSL. Keep in mind that this model is limited to 1,000 units, which means the target group for the modification is not as large as it is for the widely available M4 model.
