Indianapolis 500 is the first racing game by Papyrus Design Group, designers of modern-day classics like NASCAR Racing and IndyCar Racing.
It's basically an excellent 3D simulation of the 25-mile Indianapolis 500. Not a simple arcade racer, where fast reactions are enough to lead to success, but a - for its time - very detailed simulation with great graphics, nice music and sounds by Rob Hubbard and many aspects of the racing-car open for modification. A great classic. Sadly, the game features only the Indy 500 track with no possibility to edit or add new ones. Here is some more information from MobyGames:
Indy 500's graphics are simply stunning considering the system requirements. You cannot find a PC that won't run this game well. The sound is also quite good; if you have an Adlib or Sound Blaster, the engine sounds are amazingly realistic. That's not to say Indy 500 is an arcade game--when it says "simulation", it means it. You can adjust your spoiler, outer and inner tire pressure, and even the amount of fuel you have in your tank to shave precious seconds off of your lap. Also, the physics are true to life: If you enter a corner too fast, centrifugal force pushes you to the outside of the track, tires squealing.
Two thumbs up for this classic that is a forerunner to Papyrus' immensely successful racing series that continues to this day with NASCAR 4 and beyond.
