Because the Beta lacked a career economy, the car list was unlocked. Players had access to a wide array of vehicles, but the list was not identical to the final game. It served as a "best of" selection, allowing testers to jump straight into competitive races without grinding for credits. Notably, the physics engine in the Beta sits somewhere between Gran Turismo 3 and the final version of GT4 , feeling slightly looser and more forgiving than the stiff simulation of the retail disc.

Instead, the series wouldn't see a fully realized online mode until Gran Turismo 5 Prologue on the PS3 years later. Because the Beta lacked a career economy, the
