The BMW M3 CS

 The BMW M3 CS

Continuing the celebrated lineage of legendary CS models is the very special, limited-edition 2024 BMW M3 CS. Today, CS stands for “Competition Sport”; the designation given to exclusive BMW M models equally at home on road and track. More power, unique chassis calibration, and intelligent lightweight construction featuring carbon fibre reinforced plastic (CFRP) components deliver an exhilarating performance experience without sacrificing the functionality and everyday usability of the BMW M3.

The 2024 BMW M3 CS teams a 543-hp inline-6 with an 8-speed M Steptronic transmission and the M xDrive intelligent all-wheel-drive system. Together, they hurl the M3 CS from 0-100 km/h in only 3.4 seconds.

The new BMW M3 CS will be built in limited numbers at BMW Group Plant Munich starting in March 2023.

M TwinPower Turbo inline-6 with Motorsport experience.

Under the lightweight CFRP hood of the 2024 BMW M3 CS is an upgraded version of the high-revving inline 6-cylinder engine with M TwinPower Turbo technology developed for the M3 and M4. This 3.0-litre unit also forms the basis of the engine that powers the BMW M4 GT3 and boasts a wealth of technological details derived directly from racing experience. Its crankcase has a sleeveless, closed-deck construction and is extremely rigid, making it suitable for very high combustion pressures. The forged lightweight crankshaft aids power build-up with its high torsional resistance and allows for high revs. The cylinder head has a 3D-printed core, allowing the coolant ducts to be routed in an optimum arrangement for temperature management that would be impossible to achieve using conventional metal casting methods. The oil supply system is designed to handle the specific challenges of track use, as is the cooling system.

The S58 engine in the M3 CS receives a 40-hp increase over the unit in the M3 Competition with M xDrive, for a peak of 543 hp from 6,250 to the 7,200 rpm redline. This increase in power was achieved primarily by raising the maximum boost pressure of the two mono-scroll turbochargers from 24.7 psi to 30.5 psi and making some model-specific changes to the engine management.

Just as important as the power at the top of the rev range, the engine produces 479 lb-ft of torque from a low 2,750 rpm all the way to 5,950 rpm. Specially-designed engine mounts create an extremely rigid connection between the engine and the vehicle’s structure. Drivers will notice throttle inputs result in sharp engine response and direct transmission of power and torque to the drivetrain.
