Goodwood represents every type of motoring and motor sport which very much mirrors what we aim to achieve with Gran Turismo and so it is very special that we have forged this partnership. Yamauchi said, 'I have always been a huge admirer of the Festival of Speed and what Lord March has achieved, I love the incredible range of cars on display – from the priceless, rare and exotic, to the latest family hatchbacks and full on racing cars – I love the challenge of the Hill Climb and the rally stage. This gave the game developers the idea to base a track here due to the wide variety of vehicles that use the hill climb in front of 185,000 spectators. The 1.16 mile strip of road that runs through the grounds of the Earl of March's family home hosts the annual Festival of Speed, where a variety of cars from throughout motorsport and the automobile industry as a whole try to set the best time they can along the narrow course. The developers announced that the Goodwood Festival of Speed hill climb course would be included on the game. The Monster Tajima E-Runner Pikes Peak Special is one of the new electric cars in the game. An early build of Gran Turismo 6's updated physics was shown to the public when GT Academy 2013 was released on the PlayStation Store on July 2 the same year. Kazunori Yamauchi said at the official announcement that Gran Turismo 6 would feature 71 layouts of 33 tracks, 1200 cars, a more flexible rendering engine that features adaptive tessellation, and a more simplistic user interface with faster loading times. Gran Turismo 6 was announced on May 15, 2013, when Sony Computer Entertainment Europe hosted a celebration of the 15th anniversary of Gran Turismo at Silverstone Circuit in the United Kingdom. In February 2013, Sony Computer Entertainment Europe’s senior vice president Michael Denny claimed that Gran Turismo 6 would remain a PlayStation 3 title, despite the unveiling of the PlayStation 4. They revealed that Mount Panorama would be included in Gran Turismo 6, making it the first Australian race track to be featured in the series. In March 2012, employees were seen on site at Mount Panorama in Bathurst, New South Wales, Australia, photographing and scanning the track.

In November 2011, the Gran Turismo series' creator, Kazunori Yamauchi, said that he and his team at Polyphony Digital were working on Gran Turismo 6.
