The BMW M4 CSL represents the pinnacle of the M4 lineup, designed to be lighter, more powerful, and visually striking with its distinctive ducktail spoiler. While its standard 543 horsepower is already impressive, G-Power takes it a step further by offering three levels of power upgrades, complemented by carbon fiber components and forged wheels to enhance both performance and aesthetics.
G-Power's G4M CSL Bi-Turbo shares the same performance enhancements as the G3M CS Bi-Turbo but comes in a more alluring two-door design. Unlike the more overt visual modifications seen in Manhart's MH4 GTR II, G-Power opts for a subtler approach. The G4M CSL Bi-Turbo features a Venturi carbon fiber hood and engine cover, emphasizing the power beneath, while the stock front splitter can be paired with matching accents for the bumper intakes. Additional visual flair is provided by a set of red-accented decals around the body.
The modified M4 CSL rides on new forged wheels available in Hurricane RR or Hurricane RS designs, measuring 20 inches at the front and 21 inches at the rear. For those looking to personalize their vehicle further, G-Power offers interior upgrades such as carbon fiber shift paddles, velour floor mats, and new upholstery options to elevate the driving experience.
Under the hood, BMW M's twin-turbo 3.0-liter six-cylinder engine receives significant enhancements. The top-tier GP-720 package boosts the engine's output to a remarkable 709 horsepower and 850 Nm of torque, and also raises the top speed limiter to 320 km/h. This is achieved through new engine software and a comprehensive "Deeptone" exhaust system that includes sport downpipes with high-flow 200-cell catalytic converters, as well as new center and rear mufflers.
The mid-level GP-670 option offers 661 horsepower and 800 Nm of torque. This setup retains the factory downpipes but includes upgraded center and rear exhaust mufflers, along with G-Power's proprietary software.
For those seeking a more modest enhancement, the entry-level GP-620 package delivers 612 horsepower and 750 Nm of torque through software adjustments and an axle-back exhaust muffler. Regardless of the chosen package, all G-Power’s BMW M4 CSL variants feature dual tailpipes, available in sizes of 100 mm and 110 mm.
G-Power offers each upgrade individually, allowing M4 CSL owners to customize their vehicles to their liking. Given the limited production run of 1,000 units for the M4 CSL, these modifications cater to a niche market compared to the more widely available M4 variants.
Overall, the BMW M4 CSL, already a high-performance marvel, is taken to new heights by G-Power’s expertly engineered upgrades. With options ranging from subtle tweaks to substantial power boosts, M4 CSL owners can transform their vehicles into truly bespoke driving machines, marrying exceptional performance with personalized style.
