The 2025 BMW M4 CS breaks the cover with a 543 HP inline six-cylinder engine

Behind the distinctive M performance features of the new M4 CS is the company’s retuned 3.0L S58 inline 6-cylinder engine with 8-speed M Steptronic transmission and M xDrive intelligent all-wheel drive. This powertrain has been retuned to produce more power and instantaneous and maximized response, which in turn helps this car accelerate from 0 to 100 kmph in 3.4 seconds. It has an electronically limited top speed of 302 kmph. This engine also serves as the basis for the engine of the BMW M4 GT3 racing car. During its testing on the Nurburgring’s 20.76 km Nordschleife circuit, which is the ultimate litmus test for all BMW M cars. On the circuit, the 2025 BMW M4 CS recorded an official notarized lap time of 7 minutes 21.99 seconds.

BMW has maintained the track-focused character of its M range in the new M4 CS. The engine of the new BMW M4 CS benefits from the development expertise of BMW’s M division and the many years of racing experience behind it. The engine starts with an extremely rigid crankcase, which features a sleeveless closed deck construction and is designed to withstand very high combustion pressure. The lightweight forged crankshaft provides exceptional torsional strength, which in turn contributes to quick power delivery and willingness to accelerate. The weight-saving powder-coated iron coating of the cylinder bores reduces friction losses. The cylinder head itself has a 3D-printed core, allowing the coolant passages to be routed in an optimal arrangement for temperature control that would be impossible to achieve using conventional metal casting methods. Even its oil supply system, like the cooling system, is designed to meet the specific challenges of track use, including sustained high revs and extreme lateral acceleration. All this engineering and technical wizardry results in a maximum power of 543 hp, which is an increase of 20 hp compared to the BMW M4 Competition Coupé with M xDrive.

Acoustics are really important in an M car, both for the company and for M model purists. The power delivery of the M4 CS 2025 is accompanied by a moving soundtrack generated by the double branch exhaust system, which features electrically controlled fins, a titanium rear silencer with a design that minimizes weight and two pairs of exhaust outlets finished in matte black. Its exhaust notes also change according to the powertrain setup selected through the M Setup menu. BMW highlights that in Sport and Sport+ modes the notes are noticeably more aggressive and resonant.

The 2025 BMW M4 CS features an all-wheel drive system and even features carbon fiber shift paddles on the steering wheel. Torque distribution is managed through the M xDrive system, which uses an electronically controlled multi-plate clutch in the transfer case to smoothly distribute engine power between the front and rear wheels to maximize traction, agility and directional stability. The company has even optimized the multi-plate clutch oil delivery system to ensure that the all-wheel drive system continues to operate effectively even during intense track use.

The rear-wheel bias of the M xDrive system and its integration with the fully variable M active differential on the rear axle contribute to the characteristic M feel, whether when accelerating in a straight line or when cornering. Additionally, the M Setup menu allows you to select 4WD Sport mode, which directs a greater proportion of the engine’s torque to the rear wheels. Drivers can also completely disable the DSC (Dynamic Stability Control) system and activate pure rear-wheel drive via 2WD mode.

The 2025 M4 CS also features electronically controlled dampers in the form of the M4 CS-specific M Adaptive Suspension setup along with variable-ratio M Servotronic electromechanical steering and integrated braking system. It is equipped with M Compound brakes with your choice of red or black painted calipers. The optional M carbon ceramic brake calipers can be specified in red or gold finish. It also features forged M alloy wheels as standard, available in matte Golden Bronze or matte Black. These wheels wear 275/35 ZR19 tires at the front and 285/30 ZR20 at the rear.

In terms of sporty styling, the 2025 M4 CS features a carbon fiber roof and lightweight hood, a front splitter, front air intakes, exterior mirror caps, a rear diffuser, a Gurney-style rear spoiler, and a rear spoiler. exhaust. The use of lightweight materials also extends to the interiors with the use of a lightweight center console, shift paddles, M Carbon bucket seats and other interior trim. This has resulted in the M4 C being 35kg lighter than the M4 Competition Coupé.

In terms of features, the 2025 M4 CS comes equipped with features like BMW OS 8.5, 12.3-inch instrument cluster, 14.9-inch infotainment system, TPMS, BMW iDrive, voice commands, automatic climate control, heated seats, heated steering wheel, M Drive Professional with M Drift Analyzer and M Laptimer, Automatic Start/Stop, M Mode, Track Mode, driver assistance systems and HUD.
