Gran Turismo 7 receives major physics update in patch 1.71

Polyphony Digital has released update 1.71 for Gran Turismo 7, introducing significant changes to the game’s vehicle dynamic behavior. The update focuses on a revamped tire grip algorithm designed to simulate the transition between full traction and sliding more gradually, providing players with more progressive feedback when approaching the limit of adhesion.

Beyond tire physics, the patch includes optimizations to steering geometry, suspension damping, and mechanical layouts to improve load transfers and road surface detection. The update also features revised rolling resistance, tire heating, and wear values. These technical improvements, potentially influenced by a collaboration with Dunlop, have sparked intense discussion within the player community regarding their impact on online rankings and daily driving experiences.
