Sony's just confirmed that a Gran Turismo 5 time trial demo will be hitting PSN next week, on December 17.
The 'GT Academy 2010 Time Trial' download will help find the top twenty players from each participating country, after which they'll be invited to a final face-off and, eventually, invited to the GT Academy 2010 itself which involves real cars.
"Last year the GT Academy programme unearthed a real driving talent in the form of Lucas Ordenez from Spain, who after winning the GT Academy went on to drive for the Nissan PlayStation race team and take an astonishing second place in the GT4 Championship - all in his first season," explains Sony.
As for the demo: "It will be the first opportunity to get a hands-on taster as to what Yamauchi-san and his Polyphony team have been carefully crafting and polishing at their Tokyo base," says the PlayStation blog.
It'll contains a new GT5 course, and the Nissan 370Z in two guises: "Firstly a blisteringly fast, race-tuned monster and secondly an only slightly less fearsome non-tuned version," says Sony. Here's a GT Academy video:
