This is from IMDB regarding Claude LeLouche (now 76):

According to recent claims by Claude Lelouch, he was driving his own Mercedes in the film, and later dubbed over the sound of a Ferrari 275GTB to give the impression of much higher speeds. Calculations made by several independent groups using the film show that the car never exceeds 140 km/h (85 mph), which seems to lend credence to his recent comments.

Lelouch was arrested shortly after the film was screened but was later released without charge.

Until recently, there was no confirmation of who was driving or what car he was driving. Over the years, various sources claimed an F1 driver was at the wheel of a Le Mans Matra 675, Ferrari 275 GTB, or an Alpine A110. However, Claude Lelouch confirmed on his official website in March 2006 that he was driving, and it was a 6.9 litre Mercedes.

The film was shot in a single take, without any special effects or stuntmen, with the director driving the car.

The idea for this film came to Claude Lelouch after hiring a gyro stabilized camera mount for a film he was working on at the time.

Three people were in the car, with Claude Lelouch at the wheel.
