A Geneva Motor Show isn’t at all complete without the participation of one of the best tuners in the world, one that also calls Switzerland its home.

Days before the opening of one of the biggest auto shows in the world, we finally get an idea what Mansory has up its sleeve. One of their Geneva presentations is a new program for the McLaren MP4-12C, which comes complete with a full aero kit and a significant performance upgrade.

Diving into the body package, the British supercar received a host of new components, all of which were designed to deliver improved aerodynamics. The ultralight bonnet with exposed carbon fiber sections and the proprietary daytime driving lights are a good place to start. The program also comes with a new front and rear apron, new mirror housings, newly designed side sills, a new rear wing profile, and a new diffuser. All the components of this aero kit are made of carbon fiber, providing improved acceleration and braking power, while also improving the supercar’s fuel consumption due to the drastic weight savings.

As for the interior, Mansory knows only to use the finest materials in their programs and it’s no exception on the MP4-12C, thanks to plenty of high-quality leather stitched with contrasting thread by the in-house saddlery. In addition, there are also plenty of carbon fiber elements, as well as a newly designed airbag sports steering wheel and aluminum pedals.[...]
