Rediscover the Original GTA Vehicle Physics with Patrick Kerr’s Revamped Simulation

As anticipation for GTA VI builds with its rumored advanced graphics, some gamers are taking a nostalgic journey back to the roots of the Grand Theft Auto series, which started 29 years ago. The original game, launched in 1997, was revolutionary for its time, offering diverse NPC interactions and dynamic gameplay that allowed players to simply drive around and explore, while appreciating the classic vehicle physics that captured the essence of real-world driving.

GTA Original Vehicle Physics: A Look Back

Patrick Kerr, a former programmer at DMA Design—now Rockstar North—has recreated his initial 2D simulation that defined the original game’s vehicle dynamics. This simulation, originally a simple wireframe demo crafted in GFA BASIC on an Atari ST, was later adapted to C for the game itself. Kerr has now transformed it into a JavaScript version with improved visual elements. Players can experiment with different modes such as Car (1), Ship (2), or Brick (3), using the number keys to switch. This showcase of the vehicle system allows enthusiasts to experience the vehicle simulation that set the stage for future game mechanics. Unique features include the ability to toggle side collision barriers with B and adjust vertical gravity for Ship and Brick modes with G. The camera’s dead zone can be toggled with Z, and speed-based zoom with X, similar to GTA’s mechanics.

For developers and enthusiasts interested in the technical underpinnings, Kerr has detailed the system’s workings on his website. This display of vehicle dynamics is available to try at Motion Lab.
