2025 BMW M4 CS revealed, Australian price confirmed

The 2025 BMW M4 CS will arrive in Australia later this year with upgrades similar to the M3 CS.

Improvements for the M4 CS include carbon fibre-reinforced plastic (CFRP) components, increased engine output, a sportier chassis setup, and design changes.

CS-specific revisions allow for a Nürburgring time of seven minutes and 21.989 seconds – seven seconds faster than the M4 Competition.

BMW has allocated 50 examples to the local market, with customer deliveries set to commence between October and December 2024.

The CS engine features a sleeve-free, closed-deck construction, forged crankshaft, wire-arc sprayed iron bore coating, 3D-printed cylinder head core, and more rigid engine mounts.

This enables coolant duct routing that cannot be achieved using conventional metal casting methods.

The maximum power output for the M4 CS is 405kW – up 15kW over the M4 Competition xDrive – achieved by increasing boost to 2.1 bar and tweaking the ECU. Peak torque is 650Nm from 2750rpm to 5950rpm.

Performance is improved over the M4 Competition, with standing starts to 100km/h and 200km/h in 3.4 seconds and 11.1 seconds, respectively.

Rolling acceleration is fierce, reflecting the substantial torque available throughout the rev range, with 80km/h to 120km/h in 2.6 seconds in 4th gear and 3.3 seconds in 5th. Top speed is electronically limited to 302km/h.

The exhaust system now features a titanium rear silencer. It has “racecar undertones” in Sport and Sport+ modes.

Power is still transferred to the road by the M xDrive system. This uses an electronically controlled multi-plate clutch in the transfer case to distribute the engine’s power smoothly between the front and rear wheels.

The clutch’s oil supply has been optimised to ensure effective performance during track sessions. Drivers can switch off the DSC system altogether and also engage rear-wheel drive via a 2WD mode.

Forged alloys (19-inch front / 20-inch rear) are fitted as standard with track tyres (275/35 ZR19 front / 285/30 ZR20 rear) as standard fitment. High-performance road tyres are available as a no-cost option.

CS-specific chassis tuning has been applied to the front strut brace, axle kinematics and amber, dampers, auxiliary springs and anti-roll bars.

The electromechanical steering with variable ratio is model-specific, and M Dynamic Mode pushes back the intervention points for the DSC system various stabilising measures.

Forged alloys (19-inch front / 20-inch rear) and track tyres (275/35 ZR19 front / 285/30 ZR20 rear)are standard, with high-performance road tyres available as a no-cost option.

The roof, bonnet, front splitter, front air intakes, exterior mirror caps, rear diffuser and Gurney-style rear spoiler are all made from CFRP on the CS.

A four-kilogram weight saving is also achieved with M Carbon bucket seats using CFRP for the seat cushion and backrest structures, and the titanium exhaust. Overall weight is down by around 20 kilograms compared to the M4 Competition.

The 2025 BMW M4 CS is priced from $254,900 before on-road costs – a $68,000 increase over the M4 Competition xDrive.
