Left is the director's unbroadcast version of the R8 commercial. Below is a link to the broadcast version of the film....It's an interesting comparison.

Raf Walthion, directing in Brussels for CZAR (Brussels) and TEMPOMEDIA (Hamburg), needed a huge list of special effects, shot inside the engine; the beating heart of the Audi R8, the diesel powered racing car which won the Le Mans 24 hrs. race.We cooperated with belgian special-effects expert Thierry Cambray and Robert Pachowski from Amsterdam. We developed shots with Raf of diesel going into the tank; diesel being vapourised through the valves into the cylinder; explosions in the cylinder; flames travelling through channels in the engine, and many more practical special-effects. Most shots were shot at 1000 frames using the Phantom camera.

Below are many images taken on the filmset during shooting...
and workshop photos and films which we used to communicate with director Raf Walthion in Brussels.
