Gran Turismo 7 Easy Credit Glitch Will be Patched Soon

A new money earning glitch in Gran Turismo 7, leveraging the recent change in credit rewards introduced in the Spec II update, has now made it onto Polyphony Digital’s “Known Issues” radar ready for a future fix.

Although, technically, the glitch has been around for a very long time now, it’s only the introduction of increased rewards in Custom Races that have turned it into a veritable money spinner and by far the quickest way of earning repeatable credits in the game right now.

In essence it takes advantage of a flaw in how Custom Races assess the difficulty of a race and, therefore, the credit rewards for winning the event — and it’s that specific flaw that PD has added to the “Known Issues” page.

Put simply, the game determines race difficulty based on the base Performance Points (PP) of the cars selected for the race without taking any modifications to those cars into account.

That means that players can select extremely high performance cars and severely hamstring them with a combination of terrible tires and very short gearing, to make them easy to beat in much lower PP vehicles, while the game still classes them as top class vehicles.

Additionally, the player car can be one of the slowest in the game but, by various tuning methods — including engine swaps — turned into a high speed weapon while still being treated as an ancient, low-powered box.

There are various methods floating around the internet, including a dedicated thread right here on GTPlanet, detailing the best ways to do this. However virtually any approach is capable of delivering over four million credits an hour.

The preferred method involves a convoy of 2500hp+ Dodge Tomahawk X cars on Comfort Hard tires and geared to below 150mph, with the player driving a K20 turbo-swapped Abarth 595 — though significant additional work has to be performed to make it drive without crashing or attempting to turn itself inside-out.

This approach, when used at Daytona Tri-Oval, also generates the possibility of an “AFK” — “away from keyboard” — earner. As the player will gain a Clean Race Bonus so long as they don’t hit the AI cars, it’s possible to use rubber bands to keep various controller buttons in place (with motion steering, to avoid stressing the thumb sticks) to scrape around the outside wall.

It’s a technique that won’t be available for long however, with PD looking to close the loophole in a future update. The game’s Known Issues page currently includes a note about the incorrect calculation, so we’re likely to see this changed by the time of the next content update.

That should come as no surprise, with Kazunori Yamauchi previously stating that he’d like to avoid “a situation where a player must mechanically keep replaying certain events” in Gran Turismo 7.
