BMW M4 CS G82 - 2025

The 2025 BMW M4 CS (G82) - The All-Weather Apex Predator

The 2025 BMW M4 CS (G82) emerges as the definitive statement for the modern M car, meticulously engineered to occupy the "sweet spot" between the formidable M4 Competition and the uncompromising, track-purist M4 CSL. The "CS" or "Competition Sport" designation signifies a more powerful, lightweight, and focused machine, but the G82 M4 CS fundamentally evolves this philosophy. Its most pivotal engineering decision is the standard inclusion of the M xDrive all-wheel-drive system, representing a deliberate shift from rear-wheel-drive purity to ultimate, all-condition effectiveness. This makes the M4 CS not just a faster car in the real world, but a more accessible and confidence-inspiring super-coupe for a wider range of drivers.

At its core lies a specially tuned S58 3.0-liter twin-turbocharged inline-six engine, producing 543 horsepower and 479 lb-ft of torque—figures identical to the more extreme M4 CSL. This power increase over the M4 Competition is achieved primarily by raising the turbochargers' maximum boost pressure to 30.5 psi, managed by model-specific software. Power is channeled through a CS-calibrated eight-speed M Steptronic automatic transmission to the intelligent M xDrive system. This rear-biased drivetrain offers three modes—4WD, 4WD Sport, and a pure 2WD setting—allowing the car to transform from a sure-footed all-weather weapon into a traditional RWD drift machine at the touch of a button.

A core tenet of the CS philosophy is intelligent lightweighting. The M4 CS sheds approximately 77 lbs compared to the M4 Competition xDrive, achieved through the extensive use of Carbon Fiber Reinforced Plastic (CFRP). This lightweight, high-strength material is used for the roof, hood, front splitter, rear diffuser, and numerous interior components, including the center console and the standard M Carbon bucket seats. Further weight is saved via a titanium rear exhaust silencer and weight-optimized forged alloy wheels. These reductions are complemented by a bespoke chassis tune, featuring unique settings for wheel camber, dampers, and anti-roll bars, plus a rigid rear-axle subframe connection that eliminates rubber bushings for enhanced precision and feedback.

The exterior design is an exercise in functional aggression, with CSL-style yellow daytime running lights, a minimalist frameless grille, and a host of exposed carbon fiber aerodynamic elements that increase downforce. The interior is a purist's office, dominated by the supportive but firm M Carbon bucket seats, which are a point of contention for their compromised daily comfort. Ergonomic trade-offs, like the deletion of the center armrest and cupholders, are made in the name of performance. This spartan focus is contrasted by the high-tech BMW Curved Display running the latest iDrive 8.5 system, creating a unique blend of a hardcore track car and a modern luxury vehicle.

On the road, the M4 CS is firm but has a "commendably compliant" ride, making it far more livable than the brutally stiff M4 CSL. On the track, it is a devastatingly effective weapon, validated by its official Nürburgring lap time of 7:21.99—shockingly close to the lighter, RWD CSL. The M xDrive system provides ferocious, confidence-inspiring grip, allowing drivers to exploit the car's immense power with security.

Priced from $123,500 and with a limited production run of approximately 1,700 units globally, the M4 CS is an exclusive proposition. It commands a significant premium over the M4 Competition, a car that offers the majority of the performance for less money. Against rivals like the Porsche 911 GTS, the M4 CS is more aggressive and a better value, though the Porsche offers superior steering feedback. Compared to the Chevrolet Corvette Z06, the M4 CS is outmatched in raw track pace but offers far greater practicality and all-weather usability.

Ultimately, the 2025 BMW M4 CS is a triumph. It is not a car of compromise, but one of calculated duality, blending breathtaking all-weather performance with four-seat practicality. It is the definitive M4 for the enthusiast who desires a vehicle that can challenge supercars on a track day and still be driven with confidence year-round, and who values the exclusivity and bespoke engineering that the "CS" badge represents.
