As promised, the demo for Gran Turismo 6 is now available on PlayStation Network.
The demo will guide players through a series of events in a GT Academy-themed driving school, which will unlock the final event at Silverstone which features several challenges. Completing them will unlock bonus content in the main game. The demo features various Nissan cars, including the Leaf, the 370Z and the GT-R.
The demo will also be removed on the 28th August 2013. Gran Turismo 6 itself is due this Holiday 2013 for the PlayStation 3.
