The Radical SR8 is one of the fastest cars on the planet right now. This insane ball of horsepower and fury can be legally piloted on public streets and is fit for track competition right out of the box. Powered by a V8 with 455 horsepower and weighing into the same weight class as a pile of feathers, the car is a ballistic missile with fenders. How fast is it? Quick enough to lay down sub seven-second Nurburgring lap times like it was taking a stroll through the park. Do yourself a favor and check out the video to see for yourself. Here’s hoping the Radical SR8 shows up in Gran Turismo 5. [Source: 0-60]
