Video: Fast & Furious 6 'flip cars'

It seems the producers of the new Fast and Furious film just can't help showing off. Not content with hiring out government buildings in London to pose as high-class nightclubs, the film-makers have also put out a behind the scenes video showcasing their latest mad creation, flip cars.

The problem was a basic one: how to create more on-screen automotive carnage. The solution required a bit more thought, particularly after director Justin Lin ordered movie stunt boffins to create a car that could drive head-first into another and launch it into the air.
