Polyphony Digital has slipped out a fresh version of Gran Turismo 7’s “Beyond the Apex,” the free in-game and online reference guide that walks players through car culture, racing fundamentals, and the mechanics under the hood. The update landed without any real fanfare, and at first glance it’s easy to miss why it happened at all.

The stated reason is physics. Polyphony points to revisions in the driving model as the trigger for the refresh, which suggests the studio wanted the guide’s explanations to line up with how the cars actually behave after recent tuning. In practice, though, the visible differences look modest. Much of what’s changed reads more like a reorganization — sections shuffled around — than a wave of genuinely new material. If you were hoping the guide would spell out exactly what moved in the physics engine, it doesn’t lay that out in plain terms.

Why it matters to sim racers: “Beyond the Apex” is one of the few first-party places Polyphony bothers to explain its own systems, so any note that physics has been touched is worth clocking — especially for anyone who’s noticed their setups or braking points feeling slightly off lately. The catch is that this update raises the question more than it answers it. A guide citing physics changes without detailing them tells you something shifted, but not what or how much. For now, the honest read is that the wheel time in your own garage will tell you more than the guide does. Treat it as a nudge to go re-test your reference cars rather than a patch note you can actually study.
