The key factors in the standout performance attributes of the new BMW M4 CSL can be found in its name. Lightweight design has played a central role at BMW M GmbH from day one. In 1973, the BMW 3.0 CSL developed by BMW Motorsport GmbH won the European Touring Car Championship in its first attempt – thanks in no small measure to a commitment to cutting the weight of its series-produced donor model. Today, the CSL designation stands for “Competition, Sport, Lightweight" and identifies high-performance models with very high power, rigorously reduced weight, and a track-focused character.

Intelligent lightweight design was a fundamental strategy in the development of the new BMW M4 CSL, one that was applied on a detailed level. A focus on the attributes considered essential for an elite sports car was accompanied by the selective use of materials, meaning all the performance and functionality the customer expects is present, but while adding significantly less weight.

For example, conventional components for the exterior and interior, powertrain and chassis were replaced with lightweight model-specific alternatives. Fitting M Carbon full bucket seats alone reduced weight by 53 lbs, while a further 46 lbs were saved by removing the rear seats and seat belts and integrating a partition between the cabin and luggage compartment. Chassis alterations, including the addition of standard lightweight M Carbon ceramic brakes and forged light-alloy wheels, springs and struts, reduced weight by another 46 lbs. Switching to ultra-lightweight sound insulation and reducing the amount used saved another 33 lbs. The use of CFRP components on the outside and inside of the 2023 BMW M4 CSL saves an additional 24 lbs. A titanium rear silencer cuts more than 9 lbs from the weight of the exhaust system. Detail modifications shave another 8 lbs from areas including the BMW kidney grille, rear lights, floor mats and automatic climate control.
