Earlier this week, we showed you some of the souped-up super cars that are being used for DreamWorks' high-octane video game adaptation Need for Speed, such as the Saleen S7 and Bugati Veyron. When you have cars as fast as this flying down the road, you need camera-mounted vehicles that are just as fast to capture all the action, which is exactly what we see in today's featurette. The production custom built several different cars to achieve what they need, including the Ford GT Mustang with a Saleen supercharger, which puts out 625 horsepower, the Audi A6, an unspecified Ferrari and many more in director Scott Waugh's action-thriller, arriving in theaters March 7.
