Launching to celebrate the firm's partnership with Nissan on the GT Academy programme, the updated racing release includes the original game, as well as all post-launch DLC.
Additional content includes 'Car Pack 1 and 2', 'Course Pack 1 and 2', the 'Special Paint Pack', the 'Racing Gear Pack' and the Nissan GTR driven in this year's Nurburgring 24-hour race by series creator Kazunori Yamauchi.
"GT Academy has captured the imagination of many Gran Turismo fans," explained Yamauchi.
"It is exciting to watch what Lucas Ordóñez, Jordan Tresson, Jann Mardenborough and Bryan Heitkotter in the USA are achieving in their new racing careers with Nissan.
"People can now see that it is possible to make the switch from being a fast gamer to become a real racing driver. We wanted to mark the tremendous success of GT Academy with the very latest version of GT5."
Releasing exclusively for the PS3 on September 26, the Academy Edition will be available for £19.99.
The Academy Edition is similar to Gran Turismo 5 Spec II, which launched in February throughout Japan.
Announced last year, Spec II also included post-release DLC and enhancements, such as October's 2.0 title update, which added interior views for all standard cars, improved car physics and the ability to save progress during endurance races.
Sequel Gran Turismo 6, meanwhile, was confirmed by Polyphony Digital last year.
