BMW is hitting the track with two very different kind of wheeled machines: an M4 GTS converted to safety-car duty for DTM, and a wheelchair for the US paralympics team.
After seeing how they perform at the drag strip, the BMW i8 and M4 are now at Castle Combe circuit to see how they feel on the track. It's the modern hybrid versus the traditional sports coupe in this inter-brand rivalry. Check out the video to see which is better 'round a track.
Part of the joy of the SEMA Show is that all of the best tuners in the world are competing to show off their wares, and the challenge often pushes the companies into some absolutely insane directions. Case in point: Vorsteiner and its ludicrous GTRS4 wide body kit with the BMW M4.
