Thanks to a new performance exhaust, new air intake system and an engine remap, the 3.8-liter twin-turbo unit makes 670 PS 675 Nm (498 lb-ft) of torque.
As a result of this and the aerodynamic enhancements, the McLaren is supposedly capable of doing 353 km/h (219 mph).
The exterior receives a body kit by Mansory that widens the dimension of the vehicle by 60mm, it includes replacement parts for the roof, the front and rear aprons, the mirror housings and the fenders. The kit is completed with a set of 20 inch wheels.
Mansory has also worked on the interior. It includes a new airbag sports steering wheel, aluminium pedals and real carbon-fibre elements.
The Mansory MP4-12C will be officially unveiled at the Geneva Motor Show that opens to the media on March 6
