Sharing is caring!

Filling the space between the racetrack experience and soul-stirring road performance, the new BMW M4 CS celebrates racing passion with lightweight design elements for every day driving comfort.

With an increased engine output of 405 kW/550 hp, model-specific chassis tuning and minimised weight – helped by numerous components made from carbon fibre-reinforced plastic (CFRP) – the BMW M4 CS (fuel consumption, combined 8.49 l/100km; CO2 emissions combined: 232 g/km in the WLTP cycle, CO2 class: G) bring an extra edge to the BMW M4 Coupé vehicle concept of four seats, everyday practicality, advanced equipment and exclusive design features.

Production of the new BMW M4 CS will start in July 2024 at BMW Group Plant Dingolfing, with order books opening in late May. The BMW M4 CS is priced from€213,870  RRP with first deliveries in Ireland from Autumn 2024.

The new BMW M4 CS invites owners to experience the iconic M feeling in all its depth and breadth. Its distinctive character profile places it exactly midway between the new BMW M4 Competition Coupé with M xDrive (fuel consumption, combined 8.4 – 8.31 l/100km; CO2 emissions, combined: 229 – 226 g/km in the WLTP cycle, CO2 class: G) – complete with its recently introduced performance, design and equipment upgrades – and the 1,000-unit limited-run BMW M4 CSL special edition (fuel consumption, combined 8.4 – 8.25 l/100km; CO2 emissions, combined: 227 – 224 g/km in the WLTP cycle, CO2 class: G). The performance of the new BMW M4 CS is the product of M-typical racing genes, which offer constant reminders of their presence in everyday driving on the road and enjoy full expression out on the track.

The model-specific performance characteristics of the six-cylinder in-line engine in the BMW M4 CS, an eight-speed M Steptronic transmission and M xDrive intelligent all-wheel drive infuse the new model with dynamic poise and assurance. Instantaneous power delivery and optimised traction enable acceleration of 0 to 100 km/h in just 3.4 seconds. In testing at the Nürburgring’s Nordschleife circuit – the ultimate barometer for all BMW M cars – the new BMW M4 CS recorded an official time of 7 min. 21.989 sec. for the full 20.832-kilometre lap.

Six-cylinder in-line engine developed for motor sport.

The race-focused character of the new BMW M4 CS is immediately recognisable. Powered by a high-revving six-cylinder in-line engine with M TwinPower Turbo technology, the 3.0-litre has track performance from day one of its development. With a rigid crankcase featuring sleeve-free, closed-deck construction and a forged lightweight crankshaft which displays exceptional torsional resistance, both giving the engine its rapid power delivery. The wire-arc sprayed iron coating of the likewise weight-saving cylinder bores reduces frictional losses and the cylinder head has a 3D-printed core. This additive manufacturing process allows the coolant ducts to be routed in an optimum arrangement for temperature management that would be impossible to achieve using conventional metal casting methods. And the system of oil supply – like the cooling system – is designed to handle the specific challenges of track use, including consistently high revs and extreme lateral acceleration.

Bespoke performance characteristics, distinctive sound.

Racing technology provides the foundations for the extraordinary potential of the six-cylinder in-line engine, which produces maximum output of 405 kW/550 hp from under the bonnet of the new BMW M4 CS.

Representing a 15 kW/20 hp increase from the BMW M4 Competition Coupé with M xDrive, the power boost was achieved through targeted revisions to the engine’s M TwinPower Turbo technology and required no concessions in stability or durability. The adjustments focused on raising the maximum charge pressure of the two mono-scroll turbochargers to 2.1 bar and making model-specific tweaks to the engine management.

The upgrades also produce a specific take on familiar M performance characteristics, with instantaneous power delivery that continues unabated through to the upper echelons of the rev range a particularly dominant theme. The engine in the new BMW M4 CS puts its peak torque of 650 Nm (479 lb-ft) on tap from just 2,750 rpm up to 5,950 rpm and develops maximum output at 6,250 rpm and has a 7,200 rpm red line. Contributing to the excellent engine response is a model-specific engine mounting with increased spring rates; the rigid connection between the power unit and the vehicle’s structure enables direct transmission of its power to the drivetrain every time the driver presses the accelerator.

The instantly available power and high-revving character of the engine pave the way for imposing acceleration figures. The new BMW M4 CS dashes from 0 to 62 mph in just 3.4 seconds, while 0 to 124 mph takes 11.1 seconds. The mid-range sprint from 50 – 75 mph is dealt with in 2.6 seconds in 4th gear and 3.3 seconds in 5th gear. The top speed of the special edition is electronically limited to 302 km/h (188 mph).

The engine’s power delivery is accompanied by an emotionally stirring soundtrack generated by the dual-branch exhaust system, which features electrically controlled flaps, a titanium rear silencer with weight-minimising design and – in customary M fashion – two pairs of tailpipes painted in matt Black.

The engine’s acoustic presence adjusts to the powertrain setting selected via the M Setup menu. In SPORT and SPORT+ modes, the engine note gains unmissable racing car undertones, injecting aural drama during gear changes and the accompanying adjustments in rev speed.

Eight-speed M Steptronic transmission, M xDrive and active M differential convert outstanding power into imposing performance.

The engine’s drive torque is relayed to all four wheels of the new BMW M4 CS via an eight-speed M Steptronic transmission with Drivelogic, operated using either the M-specific gear selector lever on the centre console or the carbon-fibre shift paddles on the steering wheel. The Drivelogic button integrated into the selector lever allows the driver to alter the transmission’s shift characteristics as desired, with a choice of settings available: one comfort-oriented, one for sports performance and one optimised specifically for track use.

The engine’s power is channelled onto the road by the M xDrive system. This intelligent all-wheel-drive technology uses an electronically controlled multi-plate clutch in the transfer case to distribute the engine’s power smoothly between the front and rear wheels – and to maximise traction, agility, and directional stability in any situation. The multi-plate clutch’s oil supply has been optimised to ensure the all-wheel-drive system continues to perform effectively even during ultra-intense track sessions.

The M xDrive system’s rear-wheel bias and the way it teams up with the Active M Differential at the rear axle – whose operation is also fully variable – add to the signature M feeling when accelerating or powering through corners. Furthermore, the M Setup menu allows 4WD Sport mode to be selected, which directs an even greater proportion of the engine’s torque to the rear wheels. Drivers can switch off the DSC (Dynamic Stability Control) system altogether and engage pure rear-wheel drive via 2WD mode.
