The track-bred GTS may be the ultimate expression of M4 power and performance, but unfortunately that model is not ideal for everyday driving and is limited to just 300 examples. Enter the BMW M4 CS, which could be the next best thing.
The BMW M4 CS made its global debut at the Shanghai auto show this week. Slotting between the M4 Competition Package and the extreme M4 GTS, the special edition will arrive in U.S. dealerships next year.
Powered by a 3.0-liter twin-turbo six-cylinder engine, the BMW M4 CS produces 454 hp and 442 lb-ft of torque. That means it has 29 more hp than the standard M4 coupe and 10 more hp than the Competition model. Top speed is limited to 174 mph, and according to BMW's preliminary estimates, the model should hit 60 mph from a standstill in 3.8 seconds. The CS was able to lap the Nrburgring Nordschleife in 7 minutes, 38 seconds.
The M4 CS was able to accomplish this feat using a familiar seven-speed dual-clutch transmission and a suspension similar to the one found on the M4 Competition package. BMW has tuned the Adaptive M Suspension, DSC, and Active M Differential specifically for the M4 CS, taking into account the needs of track and road driving. Comfort mode allows for relaxed cruising, while Sport and Sport + modes are available for more spirited drives. The model comes with unique 19-inch front and 20-inch rear wheels wrapped in track-ready Michelin Pilot Super Sport tires.
Carbon fiber plays a major role in the exterior design. Along with a carbon fiber-reinforced plastic hood, the M4 CS also receives a model-specific front splitter made from carbon fiber as well as a Gurney spoiler lip with exposed carbon fiber. To further improve performance, the M4 CS borrows its rear diffuser from the M4 GTS, while also using large air intakes in the front apron to improve cooling.
Inside the cabin, BMW keeps weight down with light M sport seats with leather and Alcantara as well as lightweight door pull loops. Of course, there are plenty of standard creature comforts, including automatic climate control, navigation, and a BMW HiFi audio system. The door panel trim is made from compacted natural fibers.
BMW will build the special-edition four-seater in Munich and will sell it in the U.S. in 2018. Pricing will be announced closer to launch.
