Trademark and patent databases often reveal crucial insights into the otherwise secretive operations of automakers. Recently, The Drive discovered a potential comeback of the Toyota Celica through a trademark application. Building on this, the World Intellectual Property Organization has unveiled BMW’s plans, revealing through a database search for the term “CSL” in the United States that the company has filed trademarks for three models: the M2 CSL, M4 CSL, and M8 CSL, dated April 19. Additionally, a search in BMW’s home country, Germany, shows M CSL variants for all eight coupe and sedan models currently in production or set to be released soon.
The US Patent and Trademark Office’s database confirms the same three vehicles, supporting the findings of the trademark filings.
Currently, BMW does not produce an M1—previously used for a short-lived supercar—or an M7, and the 8-series has been on hold since 1999, though it is anticipated to return next year. Some insights into its design are already available, as a concept for the 8-series has been showcased, and BMW plans to compete with the M8 GTE in the 2018 World Endurance Championship.
The term “CSL” stands for “Coupe Sport Leichtbau,” or Coupe Sport Lightweight. It has not been seen on a BMW model since 2004 when the M3 CSL was produced for just one year, limited to 1,400 units. This particular model reduced weight by 240 pounds compared to the standard M3 by sacrificing some comforts and utilizing a body made from carbon fiber-reinforced plastic (CFRP), as well as a carbon fiber intake manifold.
If future CSL models receive the same treatment as the 2004 M3 CSL, we can expect them to feature CFRP or carbon fiber body panels and fewer luxurious amenities compared to their more typical M counterparts.
The Drive has reached out to BMW for additional comments, but no response has been received as of now..
