2018 BMW M4 CS-was honed at the Nurburgring Nordschleife, one of the world’s most exacting test tracks for high-performance sports cars


Unlike the BMW M4 GTS, BMW has deliberately steered the M4 CS away from a focus on the track. For example, the front splitter is not adjustable and instead of a large, adjustable wing, the rear end sports an exposed-carbon-fibre Gurney – i.e. an aerodynamic spoiler lip running across the trailing edge of the boot lid that significantly reduces rear-axle lift once again compared to the M4 with Competition Package. In the interests of everyday practicality, the M4 CS also forgoes the roll cage fitted in the M4 GTS.

The BMW M4 CS was honed at the Nurburgring Nordschleife, one of the world’s most exacting test tracks for high-performance sports cars – proof, if any were needed, that the new BMW M4 CS has been set up to deliver exceptional dynamics as well as unrestricted real-world usability. The M4 CS lapped the ‘Ring in 7 min. 38 sec., which ranks it between the BMW M4 and the uncompromisingly track-focused M4 GTS.

The excellent dynamics of the new BMW M4 CS are rooted not only in a fresh round of suspension revisions over the M4 with Competition Package in terms of spring/damper settings, but also in a moderate increase in power for the six-cylinder in-line engine. Fitted in the M4 CS, it develops 460 hp – that’s 10 hp more than in the M4 with Competition Package. Peak torque increases by 50 Nm (37 lb-ft) to 600 Nm (442 lb-ft).

Generous use of Alcantara and leather has allowed the development engineers and designers at BMW M GmbH to conjure up an interior with an enviable sporting feel. Paring down the passenger compartment to the essentials and, in so doing, achieving significant weight savings was also the declared aim with the interior door panels and the side trim in the rear compartment. Both are made from compacted natural fibres – renewable raw materials, in other words – and have been given a special carbon-fibre look. Conventional door pulls give way to lightweight loops in the BMW M4 CS. And yet, despite the rigorously sporty mindset embodied by its cabin and also expressed in the presence of lightweight M sports seats, passengers in the BMW M4 CS need not go without niceties such as single-zone automatic climate control and a high-quality, specially adapted version of the HiFi System Professional.

A sensational straight-six engine

The six-cylinder in-line engine has a great tradition at BMW, and in the new BMW M4 CS it is once again responsible for delivering performance par excellence. When compared to the M4 with Competition Package, maximum output has been increased by ten horsepower to 460 hp, which is on tap at 6,250 rpm. Peak torque of 600 Newton metres (442 lb-ft) is a whole ten per cent higher (M4 with Competition Package: 550 Nm / 405 lb-ft) and can be summoned up over a very wide rev range – from 4,000 rpm up to 5,380 rpm. These power reserves endow the new BMW M4 CS with supercar-like performance. The 0 to 100 km/h (62 mph) sprint is over in a breathtaking 3.9 seconds, for example. The top speed of the BMW M4 CS, which comes with the M Driver’s Package as standard, is electronically limited to 280 km/h (174 mph).

The high power output of the 3.0-litre engine can be attributed to its free-revving design, as well as the inclusion of two turbochargers and extremely effective charge air cooling. The M TwinPower Turbo technology at work in the BMW M4 CS employs two very responsive mono-scroll turbochargers, which combine with High Precision Injection, VALVETRONIC variable valve timing and Double-VANOS fully variable camshaft control to ensure the six-cylinder unit can deliver its power to maximum effect. Charge pressure is built up continuously from just above idling speed, while the fully variable valve and camshaft timing helps to maintain a high efficiency factor. This not only enables the engine to generate its power continuously over a very wide rev band, it can do so very economically, too. Fuel consumption and therefore exhaust emissions remain low (fuel consumption combined: 8.4 l/100 km* [33.6 mpg imp]; CO2 emissions combined: 197 g/km*). The high-revving ability of this exceptionally refined six-cylinder unit likewise benefits from VALVETRONIC and Double-VANOS technology. As a result, the straight-six under the bonnet of the BMW M4 CS has an impressively high rated engine speed for a twin-turbocharged unit of 7,600 rpm.

Power is transmitted to the rear wheels of the new BMW M4 CS via the seven-speed M Double-Clutch Transmission (M DCT) with Drivelogic that has already been successfully used in the M4 and M4 GTS models. The extremely fast gear changes mean there is no interruption in power flow, while the M Launch Control function ensures flawless acceleration from a standing start. The M DCT unit operates fully automatically, but there are also shift paddles on the steering wheel for changing gear manually. In order to cope comfortably with even the most demanding operating conditions, the seven-speed transmission comes with a dedicated oil cooler.

Equipped to the highest standard

The cabin of the BMW M4 CS is awash with fine leather and classy Alcantara. Both the driver and front passenger settle into the same specially-designed lightweight M sports seats fitted in the M4 with Competition Package. They are upholstered in Merino leather and Alcantara and guarantee optimum lateral support, even when powering around a track. At the same time, though, they are also very comfortable on long journeys. The familiar BMW M stripes have been incorporated into the front seat belts.

The most important accessory for drivers of the new BMW M4 CS is, needless to say, an M sports steering wheel. The M Alcantara steering wheel – a cost option – is wrapped in exclusive, anthracite-coloured Alcantara with blue/red M stitching and a 12 o’clock marker, and provides outstanding grip in all driving situations.

The interior trim strips are lined with Alcantara and feature prominent CS identifiers. Alcantara is a wonderfully classy yet hard-wearing upholstery material that also graces the lightweight centre console and the elbow rests in the door panelling. When it comes to the door panelling and the side sections in the rear, BMW M GmbH has taken the same groundbreaking approach as it did for the M4 GTS. These elements are made from compacted natural fibres – renewable resources in other words – and are considerably lighter than conventional door panels. The engineers have also given the surface of the door panelling a smart carbon-fibre look. There is plenty of badging to further underline the status of the new BMW M4 CS special-edition model. An illuminated M4 logo has been integrated into the backrests of the M sports seats and there are special door sill strips inscribed with M4 CS lettering.

Despite the intensely sporty focus of the new BMW M4 CS, drivers do not have to go without comforts such as single-zone automatic climate control. An advanced version of the BMW HiFi system Professional provides superb listening pleasure, and the BMW Navigation system Professional is also to be found on the extensive list of standard comfort features. Adaptive LED Headlights including BMW Selective Beam (dazzle-free high beam assistant) can be ordered as an option. The intelligent BMW ConnectedDrive Services are also available as an option, as is the BMW M Laptimer app, which can be used for recording all the details of laps around a race track, for example. Plus, almost all of the myriad other options available for the BMW M4 can also be specified for the M4 CS.
