BMW M3 E46 CSL: Exploring BMW’s sporting legend and its technical secrets

The BMW M3 E46 CSL represents the pure essence of automotive performance, equipped with exceptional technical features that have made it an industry benchmark. From its highly powerful engine to its aerodynamic design and advanced gearbox, every aspect of this vehicle has been meticulously engineered to deliver an unparalleled driving experience.

Unleashed Power: Engine and Performance

The heart of the BMW M3 E46 lies in its inline six-cylinder engine, optimized for high revs. This engine, capable of reaching 8,000 revolutions per minute, is further enhanced in the M3 CSL. BMW M engineers implemented a new air intake system with a carbon fiber manifold, increasing the air flow to the engine and enabling optimized performance..

Additional improvements, such as camshafts with extended opening times and redesigned exhaust valves, contribute to the power increase. The engine achieves an output of 360 hp at 7,900 rpm and a maximum torque of 370 Nm at 4,900 rpm, resulting in an impressive specific power output of 111 hp/liter, an extraordinary feat for a naturally aspirated six-cylinder engine.

Innovative Shifting Technology

The M3 CSL is equipped with an M sequential gearbox with Drivelogic, designed for ultra-fast gear changes, taking as little as 0.08 seconds. This technology, inspired by Formula 1, allows a smooth transition between gears, offering the driver an exceptional driving experience.

The SMG Drivelogic sequential gearbox offers several functions, including Launch Control, which enables optimal acceleration from rest, and the ability to automatically shift gears when accelerating up to top speed. In addition, the innovative M Track Mode, integrated into the Dynamic Stability Control (DSC) system, provides a sportier driving experience.

Technical Specifications and Performance

The BMW M3 E46 CSL features an aerodynamic and lightweight design, with special 19-inch aluminum wheels that contribute significantly to weight reduction. With a specific weight of only 3.85 kg/hp, this vehicle sets new standards for dynamism. The M3 CSL is expected to break the eight-minute barrier on the legendary Nürburgring circuit, a milestone for sports cars.
