Carlsson has already informed us about their power packs for the 2012 Mercedes SLK, but since the 2012 Geneva Motor Show is right around the corner, they have announced yet another performance kit dubbed the CB25 S.
This kit is part of the tuner’s "Plug-and-Drive Series" and along with a larger intercooler and a flow-optimised, stainless steel muffler it enables a new output figure of 176 kW (239 BHP).
Other than that the vehicle which will be exhibited in Geneva will feature Carlsson’s comprehensive list of exterior and interior upgrades, and to mention just a few, on the outside the German roadster features a custom spoiler with a carbon fiber front spoiler lip, a front grille that uses electro-polished stainless steel instead of plastic, a rear skirt insert, a new diffuser and a small spoiler that helps increase downforce.
The car sits on 19 inch single-part wheels and inside its cabin customers will find exclusive materials such as Nappa leather, brushed aluminium and a glass wind deflector with the laser-printed Carlsson logo.
