The brits from McLaren have released a video teaser of his upcoming supercar that will be unveiled at the 2012 Paris Motor Show.
The video, dubbed "McLaren vs. Aerodynamics – The Next Chapter" shows us the shape of the F1 successor in a wind tunnel of lights. 

The British supercar will likely use an extreme version of the MP4-12C’s V8, 3.8 liter bi-turbo engine combined with a KERS (Kinetic Energy Recovery System) system for a total output of about 1.000 HP.

In Paris the brits will show us only a concept, while the production version is set to arrive in 2013.
