Vrooooooooom! Vroooooooooooooooooom! Rrrrrrrrrhhhhhh! That's just some of the noises you can make as you while away the hours waiting for the Gran Turismo 6 demo, which is due on the PlayStation Store later today. Sony pins the demo's arrival for 8PM ET (5PM PT).

The demo includes a tutorial, four warm-up races, and various time-trial snapshots of UK track Silverstone. As detailed previously, the demo also serves as the qualifying method for the GT Academy 2013 competition, based on times for a full lap of the circuit. The watch stops for GT Academy qualification on July 28.
