This game is different from other versions of Formula 1 because it has "Chans"(Eng: Opportunity) and "Depå"(Eng: Pit) cards, and rather than a dashboard with a speedometer, tire and brake wear gauges, the player boards are gear boxes used to indicate what gear/speed the car is in as well as indicators for "Slitage"(Eng: Damage) and laps. The course is also different than other Formula 1 games.
