As we mentioned earlier, Sony will offer a free demo available as a download through the PlayStation Store. Obviously the download will only be available on the PS3. But here's the kicker the free Gran Turismo 5 Prologue Demo will be available only from October 20th until November 11th. Approximately three weeks, just in time for the release of the full version of Prologue. So you best note waste anytime if you're a Gran Turismo completist.

We also learned exactly what vehicles will be playable in the demo. We incorrectly reported earlier that the demo will feature 16 cars and three tracks. This report was based on information we received from the Tokyo Game Show build. For the Tokyo Motor Show and the download demo, a total of seven vehicles will be featured in the Prologue demo. These vehicles are the 2008 Lexus IS-F, 2009 Nissan GT-R, 2008 Mazda Atenza, 2008 Subaru Impreza WRX STi, 2008 Mitsubishi Lancer Evolution X GSR, 2008 Daihatsu OFC-1 and 2009 BMW 135i coupe. It's a pretty awesome selection especially when you remember that this is just a free download, but we're not really certain why the hell the Daihatsu is in the mix or how it got in there. Maybe it snuck in when no one was looking.

Seven cars, but only one course will be playable, Suzuka Circuit. See the shot above for the Suzuka map. A total of sixteen cars will be on-track simultaneously, but there's no online in the demo.
