BMW announced today at the 2017 Auto Shanghai the first ever BMW M4 CS, an exclusive special-edition model produced by BMW M GmbH. The BMW M4 CS lines-up between the BMW M4 Coupe with Competition Package and the uncompromisingly track-focused BMW M4 GTS. The 3.0-liter high-performance engine raises the output of the BMW M4 Coupe by 29 horsepower, to 454 hp. The state-of-the-art M TwinPower Turbo technology allows the BMW M4 CS to dip below the four-second mark for the 0 to 60 mph sprint, stopping the clock at 3.8 seconds (preliminary) while the standard M Driver’s Package raises the electronically limited top speed to 174 mph. With its two mono-scroll turbochargers, charge air cooler, High Precision Injection, VALVETRONIC variable valve timing and Double-VANOS fully variable camshaft timing, the inline 6-cylinder engine aims at higher echelons of performance and efficiency. More aggressively styled, the first ever BMW M4 CS continues the decades-long tradition of successful M special editions, which began in 1988 with the E30 BMW M3 Evolution. The first ever BMW M4 CS will be built at the BMW plant in Munich and will be available at U.S. dealerships in 2018 with pricing announced closer to market launch.
M-DCT Transmission and Competition Package suspension standard
The first ever BMW M4 CS is equipped as standard with the 7-speed M Double Clutch Transmission (M DCT) with Drivelogic. This cutting-edge transmission has a separate oil cooler and allows for gear changes in factions of a second with no interruption in the flow of power in both automatic and manual mode using the shift paddles on the steering wheel or the center gearshift lever. The long seventh gear helps keep revs low and minimize fuel consumption.
The suspension of the first ever BMW M4 CS largely mirrors that of the M4 with Competition Package. The suspension links and wheel carriers at both the front and rear axles are made from forged aluminum and are therefore extremely light, keeping unsprung masses low, improving driving dynamics. The BMW M4 CS is fitted as standard with Adaptive M suspension whose geometry has been tuned to deliver optimized performance on both the road and track. The first ever BMW M4 CS has also been honed on the most demanding test track of them all for high-performance sports cars: the legendary Nürburgring Nordschleife. Its ’Ring lap time of 7 min. 38 sec. puts the CS in the super-sports car territory.
Ensuring the best possible grip in all driving conditions are the DSC (Dynamic Stability Control) system – which includes M Dynamic Mode (MDM) – and the Active M Differential. The control systems for the Adaptive M suspension, DSC and Active M Differential have been tuned to suit the dynamic requirements of the BMW M4 CS, as has the set-up of the electromechanical steering. The driver has the option of adjusting the steering and suspension settings to their personal preferences by selecting one of three driving modes (Comfort, Sport and Sport+) at the touch of a button. While Comfort mode is particularly well suited to normal road conditions, city driving and short journeys, Sport will be the mode of choice for drivers looking to push on twisty country roads. For drivers heading out to the track, Sport+ mode will pave the way for the fastest lap times, adjusting all the relevant systems to deliver the best possible dynamics. Should the driver get a little too excited, DSC will intervene in an instant. More experienced drivers will find that M Dynamic Mode (MDM) provides a perfect balance of electronic assistance, allowing controlled drifts while still retaining DSC active, ready to intervene if necessary.
The light-alloy wheels (front: 9 J x 19, rear: 10 J x 20) designed exclusively for the M4 CS and fitted as standard with Michelin Pilot Super Sport tires (front: 265/35 R 19, rear: 285/30 R 20) are at home at the racetrack.
Exclusive M interior and exterior design
The driver-oriented interior of the BMW M4 CS places all controls at the perfect location. Lightweight M sports seats trimmed in leather/Alcantara sets the dynamic tonality that extends to the door panel trim made from compacted natural fibers and featuring lightweight door pull loops. The hood – with its characteristic air outlet rearwards of the powerdome – and roof are made from the lightweight, extremely rigid and high-tech carbon fiber-reinforced plastic (CFRP).
Standard features on board include automatic climate control, Navigation and BMW HiFi audio system adapted to the signature acoustic demands of the BMW M4 CS.
The BMW M GmbH designers have given the first ever BMW M4 CS looks that reflect the car’s high-performance potential. The signature feature of its prominent front end, complete with cutting-edge twin LED headlights, is the front apron with large, three-section air intakes. These feed an ample supply of cooling air to the high-performance engine, transmission, and the fade-resistant M compound brakes with four-piston fixed calipers at the front and two-piston fixed calipers at the rear. The new model-specific front splitter is made from carbon fiber exclusively for the M4 CS special edition. In the interest of aerodynamic efficiency, it teams up with the rear diffuser carried over from the BMW M4 GTS and the newly designed, exposed carbon-fiber Gurney spoiler lip on the trunk lid to minimize lift. Innovative rear lights with OLED (Organic Light Emitting Diode) technology introduced by BMW M GmbH exclusively for the M4 CS and M4 GTS provide a distinctive look. The front splitter, Gurney and rear diffuser, together with the long CFRP hood, M exterior mirrors and muscular wheel arches, allow the first ever BMW M4 CS to cut an extremely dynamic figure, even when it’s standing still.
