Fans of the game will notice one of the images was featured in magazine adverts and various leaflets included with select Dreamcast games.
Apparently the car used in the photoshoot didn't have an engine so had to be dragged to various shooting spots. In one of the slides you can see some of the rigging at the rear of the car, I'm guessing it was pulled backwards and snapped with a slow shutter to give the illusion of speed.
The photos where taken on 4x5 inch large-format reversal film, this is usually used for high resolution digital scanning.
