We've seen the McLaren MP4-12C exploded, we know all the details of its powertrain and layout, but how is it to drive? According to McLaren, an understandably biased source, it's "awesome." This video details the testing and development that's current underway on the test cars, which McLaren calls its XP Beta cars.

Narrated by Mark Vinnels, McLaren Automotive's program director for new vehicles, the video shows the car in action on winding mountain roads, complete with the sounds of its 3.8-liter twin-turbo V-8 engine. Vinnels also explains the work that's being done to make the MP4-12C accessible rather than intimidating, a common woe of many supercars.
