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.
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.
