This next footage in an overlay video which shows both F1 cars and FIA GT cars passing through the Eau Rouge section of the Spa-Francorchamps circuit in Belgium.
The two videos are not aligned perfectly, but it is still easy to see just how fast in a Formula 1 car in comparison with the rest of the cars on track, including some FIA GT Porsches which seem like they should change gears.
Watch the overlap video with Forumla 1 cars vs FIA GT cars below the jump.
