Virtual Grand Prix 2 1.5a

Virtual Grand Prix 2 1.5a is a game considered the open-wheeled race-car simulation which is developed by Paolo Cattani and his staff at AlasSoft using industrial automotive standards for the simulation of the dynamic components (whose parameters were tuned using real telemetry data) and tested by real one-seater drivers.

To experience something more realistic, you have to race in real race-car competitions!
However, there is also an 'arcade' mode for beginners...

VGP2 is an original MacOS game and not a port from other platforms. Therefore it is specially optimized for both MacOS Classic and for OSX. ? By slightly reducing the graphics detail you can expect very good framerate even on slow Macs, thanks to the original Mac optimized 3D engine.

VGP2 includes 20 cars, 15 fully detailed tracks, a network game mode, the 'TrackDesigner2' track editor tool with all the 15 tracks in source format and a championship mode to try to become the new 2003 World Champion. As a bonus the 'Techniques' section of the manual is written by the italian driver E.Colombo. This takes you through a mini-course in the techniques real open-wheeled drivers use to go even faster!
