Mansory will be officially releasing their tuning package for the McLaren MP4-12C at the 2012 Geneva Motor Show next week, but they’ve provided a teaser photo of their upgrade rides. At the heart of the tuning package is the power boost for the supercar’s 3.8-liter twin turbo engine. They’ve added their high-performance exhaust system, a new engine-management system and a sports air filter that increases airflow, which all results in a power boost to 660 hp and 498 lb.-ft. of torque. For the exterior, Mansory has widened the vehicles by 60mm, and the body kit includes replacement parts for the roof, the front and rear bumpers, the mirror housings and the fenders. They’ve also added a set of 20-inch wheels and gave the interior a few upgrades that include a new airbag sports steering wheel, aluminum pedals and carbon fiber accents.
