BMW M GmbH Present: The BMW M4 CS
The M4 CS fills the gap in the line-up between the M4
Coupe with Competition Package and the uncompromisingly
track-focused BMW M4 GTS. With its accentuated sporting
presence, the new M4 CS continues the decades-long tradition
of successful M special editions which began in 1988 with the
E30 BMW M3 Evolution. The new BMW M4 CS will be built
at the original BMW plant in Munich.
The M4 CS also sees BMW M GmbH introducing a new
nomenclature for its models. Positioned above the standard
M models will be the performance- boosted Competition
versions. Then come the CS special-edition models, a notch
higher still. Positioned on top are the performance-maximising
“brand shapers” which display a clear motor sport or club sport
character but are also fully road legal.
The 3.0-litre high-performance engine raises the output of the
M4 with Competition Package by 10 horsepower, to 460 hp.
State-of-the-art M TwinPower Turbo technology allows the
M4 CS to dip below the four- second mark for the 0 to 100
km/h (62 mph) sprint, stopping the clock at 3.9 seconds. The
top speed of the M4 CS, which comes as standard with the M
Driver’s Package, is electronically limited to 280 km/h (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 six-
cylinder in-line engine and takes a clear and consistent aim at
the higher echelons of performance, but is equally committed
to developing significant torque from low engine speeds and
achieving high levels of efficiency (fuel consumption combined:
8.4 l/100 km [33.6 mpg imp]*; CO2 emissions combined: 197
g/km*).

The new BMW M4 CS is equipped as standard with the
seven-speed M Double Clutch Transmission (M DCT) with
Drivelogic. This cutting-edge transmission has a separate oil
cooler and enables both automated gear changes and manual
interventions using the shift paddles on the steering wheel. It
changes gears in fractions of a second with no interruption in
the flow* Fuel consumption and CO2 figures are provisional,
were calculated as per the EU test cycle and may vary depending
on the tyre format of power, but employs a long seventh gear
to keep revs low and minimise fuel consumption over longer
motorway journeys.
The suspension of the new BMW M4 CS largely mirrors that
of the M4 with Competition Package. The links and wheel
carriers at both the front and rear axles are made from forged
aluminium and are therefore extremely light. That keeps the
unsprung masses low and benefits driving dynamics. The M4
CS is fitted as standard with Adaptive M suspension whose
geometry has been tuned to deliver optimised performance
on both the road and track. The new 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
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 – and the Active M Differential.
The control systems for the Adaptive M suspension, DSC
and Active M Differential have been modified 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 or the demands of the route at hand.
