BMW Secures Trademarks For M1 CSL Through To M8 CSL

BMW has filed a selection of CSL patent with the World Intellectual Property Organization in Germany.

A member of the Bimmer Post forums uncovered the patents which include M1 CSL, M2 CSL, M3 CSL, M4 CSL, M5 CSL, M6 CSL, M7 CSL and M8 CSL, indicating that the automaker is planning a fleet of new high-performance variants.

News of these patents come just a few weeks after BMW M boss Frank Van Meel said that a new range of CSL-badged models is being considered.

Beyond the CSL patents, BMW has also filed patents for M1 CS through to M8 CS. Whereas CSL (Coupe Sport Light) models will be performance-focused track tools, CS (Coupe Sport) vehicles will combine potent track performance with greater levels of comfort.

It’s important to note that it is extremely unlikely BMW intends on producing CS and CSL variants of the 1-Series, 2-Series, 3-Series, 4-Series, 5-Series, 6-Series, 7-Series and upcoming 8-Series. In all likelihood, most of the names have been patented to simply prevent other brands from using them.

However, it is probable that a select few new CS and CSL models will see the light of day. Hopefully, BMW doesn’t take too long to unveil them.

    This is seriously stupid.

      This is what happened when BMW watered down the “M” by putting “M” on everything. Now “M” isn’t strong enough to stand on its own and needs CSL to motivate people to buy. The Merc-AMG S & Black-Series cars don’t help BMW either.

      Of course…it is BMW news so it must be stupid…right?

        I once owned a BMW M3. So I’m not anti-BMW.

    An indication that BMW realize their current “M” offerings aren’t what the used to be.

    Must admit that particular M4 CS looks very good.

    So we’re going to pretend not to notice that BMW secured a trademark for the M1?!
