 Inspired by the 1966 film "Grand Prix", the developers chose to base the game on the 1967 Formula 1 Grand Prix season because during that period tracks were narrow and lined with trees, houses, and other elements that in a video game can serve as backgrounds to enhance the sensation of speed.In addition, the more primitive suspension of cars of the time meant that the car physics could be more visually dramatic.However, the amount of time that has passed since the 1967 Grand Prix season meant that some of the tracks the designers wanted to recreate no longer existed in their original form.
