McLaren has given the world a better look at its MP4-12C Spider with a new video and a brace of photographs. The clip shows off some of the convertible’s innards before dropping the retractable hardtop in real time. It takes just 17 seconds for the two-piece top to stow itself behind the seats with the car rolling contentedly down the track. As you might expect, it doesn’t take long for the test driver to lay into the 616-horsepower twin-turbo V8 engine, frolicking sideways and lighting the rear tires on fire. Funk Flex
