Geoff Crammond's Grand Prix 4

Grand Prix 4, commonly known as GP4 was released for the PC on June 21, 2002, is currently the last Formula One racing simulator released by the developer Geoff Crammond and the MicroProse label. Based on the 2001 Formula One season, GP4 essentially serves as a graphical and seasonal update of Grand Prix 3 which had been released in 2000 the game retained the series' legendary physics engine. However it entered the market at a far less hospitable time than its three predecessors, and the game faced stiff competition from an alternative Formula One simulation from studios such as ISI.

The game was planned for release on Xbox and GameCube consoles, but was later cancelled for unknown reasons.
