Prepare for a collapse of Sony’s servers as a demo of Gran Turismo 5 will hit the PlayStation Network on December 17th. Penrose Tackie, European brand manager broke the news on Europes PlayStation blog and enlightened us all that GT Academy 2010 will only feature a time trial mode racing a Nissan 370Z around a “specially created section of a new GT5 circuit.” Bundled within is a competition for 20 people to win a place at a national event racing against the “best Gran Turismo drivers in the country”. To enter we’ll need to play the time trial like crazy and get our best lap time into the top 20. Sounds simple but even the slightest tap on the brake button could be the difference between top winning or losing. For an example of what to expect, have a look at the trailer above (link broken!) here or continue reading to view the Nissan 370Z in all its glory.
