All-wheel drive traction launches
the M4 CS to 60 mph in 3.2 seconds
       
(May 8, 2024) BMW M has announced the all-new 2025 BMW M4 CS. With its 3-liter M TwinPower Turbo inline six bumped to 543 hp, unique chassis tuning, and targeted weight reduction through the extensive use of carbon fiber reinforced plastic (CFRP), the special edition M4 CS is equipped to attack the hills, curves, and braking zones of the world’s best circuits as well as highways and backroads.

In the usual fashion, the 2025 M4 CS adds an edge to the M4 vehicle concept with advanced equipment and exclusive design features without sacrificing the four-seat layout and everyday practicality.

The 2025 BMW M4 CS will make its world debut on Friday (May 10) simultaneously in the U.S. at the IMSA WeatherTech SportsCar Championship race at Laguna Seca and in Europe at the 6 Hours of Spa-Francorchamps World Endurance Car race. The CS will be produced alongside the other BMW M4 variants at BMW Group Plant Dingolfing from July 2024. The order books will be open from the end of May.

The new M4 CS’s distinctive character places it midway between the BMW M4 Competition Coupe with M xDrive – with all of the performance, design, and equipment upgrades introduced for model year 2025 – and the limited-run BMW M4 CSL. The performance envelope of the new BMW M4 CS is the product of an authentic Motorsport heritage, which is evident in everyday driving on the road and in full expression on the track.

The characteristic performance parameters of the inline 6-cylinder engine, 8-speed M Steptronic transmission, and M xDrive intelligent all-wheel drive imbue the new CS with dynamic poise and assurance in any situation. Instantaneous power delivery and optimized 4-wheel traction enable acceleration from 0-60 mph in an estimated 3.2 seconds. In testing at the Nürburgring’s 12.9-mile Nordschleife circuit — the ultimate barometer for all BMW M cars — the new BMW M4 CS recorded an official, notarized lap time of 7:21.99.

The track-focused character of the new BMW M4 CS is palpable throughout every journey. Under the CS’s CRFP hood lies a more powerful version of the high-revving S58 6-cylinder engine with M TwinPower Turbo technology developed for the current BMW M3/M4. This 3.0-liter unit also provides the basis for the engine in the racing BMW M4 GT3, which won the DTM touring car title in 2022 its first time out and followed that up in 2023 by delivering the IMSA WeatherTech SportsCar Championship team title to Paul Miller Racing.



The engine benefits from the development expertise of BMW M and the many years of racing experience that underpin it. The engine starts with an extremely rigid crankcase, which features a sleeve-free, closed-deck construction and is designed to handle very high combustion pressure. The forged lightweight crankshaft provides exceptional torsional resistance, which in turn contributes to rapid power delivery and a willingness to rev.

The wire-arc sprayed iron coating of the weight-saving cylinder bores reduces frictional losses. The cylinder head itself has a 3D-printed core, which 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 oil supply system – like the cooling system – is designed to handle the specific challenges of track use, including sustained high revs and extreme lateral acceleration.

The M4 CS’s maximum output of 543 hp represents a 20 hp increase over the BMW  M4 Competition Coupe with M xDrive. The increase was achieved through targeted revisions to the engine’s M TwinPower Turbo technology and required no concessions in terms of stability or durability. The adjustments primarily involved raising the maximum boost pressure of the two mono-scroll turbochargers to 30.5 psi and making alterations to the engine management parameters.

The engine’s peak torque of 479 lb-ft is fully available from just 2,750 rpm up to 5,950 rpm. Maximum power is made at 6,250 rpm, and the engine continues to rev smoothly to a 7,200 rpm redline. Unique engine mounts with increased spring rates form a more rigid connection between the engine and the vehicle’s structure, enabling 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 result in breathtaking acceleration. The new BMW M4 CS dashes from 0 to 62 mph (100 km/h) in just 3.4 seconds, while 0 to 124 mph (200 km/h) takes 11.1 seconds. The mid-range sprint from 50-75 mph is dealt with in 2.6 seconds in 4th gear and in 3.3 seconds in 5th. Top speed with the standard M Driver’s Package is electronically limited to 188 mph.

The power delivery is accompanied by a stirring soundtrack generated by the dual-branch exhaust system, which features electrically controlled flaps, a titanium rear silencer with weight-minimizing design, and two pairs of tailpipes finished in matte Black. The exhaust note adjusts to the powertrain setting selected via the M Setup menu. In SPORT and SPORT+ modes, it is noticeably more aggressive and resonant.

The model starts at $124,675 including shipping and will be built at BMW Group's Plant Dingolfing beginning in July.
