The "Revolution" spot created by Austin-based GSD&M Idea City incorporates unprecedented technology to film the combustion process of a BMW M3 V8 engine without using computer generated effects.
Filming the process was not easy. Manifolds were cut, cylinders shaved, and lighting holes were drilled in three complete M3 V8 engines for Director Raf Wathion to use special cameras and lenses to capture the action.
