The M3 CS is a lightweight, performance focused variant of the G80 BMW M3 that was available for the 2024 model year. The CS was only built in a sedan body style, with a tuned 545hp version of BMW's 3.0L twin-turbo inline six engine. This engine was paired to an 8 speed automatic transmission that powered all four wheels. As well as the additional power the CS had over regular variants, the car benefited from various weight-saving measures and dynamic enhancements in order to improve speed and cornering.
