Is BMW Reviving The Legendary CSL As A High Performance M4?

The upcoming M4 GTS might just be worthy of the name.

11 years after the wondrous, 1,400-unit limited edition E46 BMW M3 CSL – the Coupe Sport Leichtbau (lightweight) – came and went from the automotive world, it seems that this lustrous badge might just be making a comeback in the very near future. As the current-generation M4's GTS derivative nears production, some sources claim that the upcoming model might be christened the M4 CSL. But carrying this name would require some serious preparations on behalf of the new model.

Like the old CSL, the M4 CSL would present a significant weight loss over standard M4 coupes, amounting to 220 lbs according Automobile Magazine. This diet will be heavily based on the installation of carbon fiber front seats and the removal of the rear bench. Future buyers will also be given the option of ordering the car with a built-in roll cage. Visually, the M4 CSL will be given aerodynamic revisions similar to the M4 MotoGP safety car, such as a larger rear diffuser and front splitter and a massive spoiler. Underhood, the M4 CSL will employ the safety car's water injection system. With additional tweaks, the CSL is expected to produce 500 horsepower and 443 lb-ft of torque.
