How much faster is a purpose-built V8 racecar than a V8 road car? And how much faster is a V8 F1 car than both of those? Head down to Australia to find out.

These three-way track tests are always well planned to have a predictable, close finish, but it's still massively impressive to see how much the F1 car whips the other two.
