Few badges are as hallowed in the BMW back catalog as the CSL badge. Applied to legends like the 3.0 CSL and the E46 BMW M3 CSL - the only two BMW products to have worn the badge - it takes something special to earn the title. BMW has used other variants before, like the BMW M3 and M4 CS, and most recently the M2 CS, but since the E46, we haven't had another 'Coupe Sport Leicht'. Until now, that is. This isn't an official BMW build, so don't get too excited, but Marc Rutten, aka Shmarc150, has built the BMW M2 Turbomeister Edition, and it's as close to an M2 CSL as you're likely to get.

The important details to justify the 'CSL' tag are as follows. What started out as a regular M2 Competition has seen various weight-saving measures reduce overall weight by around 242 lbs - placing it in a similar ballpark to the curb weight of the E46 M3 CSL. Then, the twin-turbocharged S55 inline-six under the hood got some massaging from Beek Auto Racing in the Netherlands while the exhaust was swapped out for a full system from Akrapovic. The result: 520 horsepower and 487 lb-ft of torque.

This is routed rearwards by the standard seven-speed DCT, but it has a custom software tune from Defined Coding in the UK, which also worked its magic on the rear differential to improve handling and power deployment. The front brakes were beefed up with a 380-mm, six-pot front set from Nashin in Japan, while suspension components arrived courtesy of AST Suspension.

But the performance almost takes a back seat to how the Turbomeister looks. While the owner says that the look was heavily inspired by the BMW 2002 Hommage concept, the concept livery itself was inspired by the Jagermeister-liveried 3.0 CSL of the 1970s. The world-famous Topaz Detailing handled the aesthetic for Marc, using a mix of paint and foiling techniques for the final look. BMW even lent Topaz the 2002 Hommage to compare and match techniques.

Inside, the enhancements were minor, but the M Performance steering wheel was reupholstered with Alcantara and leather and a red 12 o'clock strip, while the paddle-shifters were replaced by a set from AutoTecknic. M performance carbon fiber and Alcantara trim abound, but puddle lights and carbon fiber door sills with an orange M2 CSL decal were made bespoke for the project.

According to Rutten, "the Turbomeister project has become the fulfillment of a dream to create a bespoke project vehicle based around a BMW M product. The deep love for the BMW & ///M brands, the M3 CSL, and the heritage storyline of the Turbomeister livery allowed me to create and showcase a set up that stays true to the historical nature of the saying 'Sheer Driving Pleasure', a passion which we should hold onto in an everchanging automotive world which is aimed at going fully electric and leaving us passionate [gearheads] behind confused of where the world really left us."
