Gran Turismo 7 Update 1.71 Adds Four Cars, Events, and Physics Overhaul

Polyphony Digital has released the August update for Gran Turismo 7, bringing the simulator to version 1.71. The patch adds four new vehicles to the roster: the 2008 Caterham Seven Superlight R500, the 2025 Hyundai IONIQ 6 N, and two 1997 Japanese sedans, the Toyota Chaser Tourer V and Toyota Mark II Tourer V. With the arrival of the Superlight, the Caterham brand is now officially featured in Brand Central.

The single-player component expands with three new events in World Circuits. Players can compete in the European Clubman Cup 600 at Circuit de Barcelona-Catalunya, the World Touring Car 600 at Suzuka Circuit, and the Japanese FR Challenge 450 at Kyoto Driving Park. In addition, the Circuit Experience section now includes the rallycross configuration of Barcelona-Catalunya, while the GT Café receives new dialogue, a seasonal menu, and engine swaps for ten vehicles.

Update 1.71 also introduces comprehensive adjustments to vehicle dynamics and physics. The developers overhauled tyre algorithms, tyre heating and wear mechanics, rolling resistance, and grip breakaway transitions. Power delivery, suspension geometry, steering response, traction control (TCS), and anti-lock braking (ABS) systems have all received revisions.

Sim hardware users on Fanatec gear also benefit from this release, which adds updated Auto Setup profiles along with FullForce support for the GT DD Pro steering wheel, requiring a device firmware update.
