Polyphony Digital’s audio team took Gran Turismo 7’s engine sound pipeline to an academic audience this week, presenting at the Acoustical Society of Japan. The slides, surfaced by GTPlanet, walk through how the studio captures and reconstructs engine audio for the game, and two of the cars pictured on the recording rig are ones nobody has driven in GT7 yet: a Lotus Evora 400 and a Mercedes-AMG One.

The presentation itself is about process. It covers how Polyphony records real engines and turns those recordings into the responsive, RPM-tracking sound you hear on track, rather than the looped samples older titles leaned on. That is the kind of detail the studio rarely discusses in public, and the fact it chose an acoustics conference rather than a marketing channel tells you the talk was aimed at engineers, not fans.

The car reveals are the accidental headline. A recording session is not a confirmation of a release, and Polyphony has not said anything official about either model coming to GT7. But studios generally do not haul a hypercar into a sound lab for fun, so both the Evora and the AMG One are reasonable candidates for a future update. Treat it as a strong hint, not a promise.

For sim racers, the substance is worth more than the speculation. Engine audio is one of the main cues you use to judge shift points and throttle behaviour without staring at the dash, and GT7’s sound has come a long way from the vacuum-cleaner era the series was once mocked for. Getting a look at how that improvement was engineered is genuinely useful context, even if the AMG One is the part everyone will be talking about.
