Forum user Digital-Nitrate of GTPlanet.net (linked above) has posted a few scans from the latest PlayStation: The Official Magazine (PTOM) which reveals both Gran Turismo 5 Night Racing and GT5 PS3 box art.
Apparently the game will have over 1,000 vehicles including Indy cars. All of which has modeled interiors, external visual deformation and mechanical damage.
170 "premium" cars also feature internal deformation. The magazine also confirms that the racing tracks will be supporting weather effects and day/night cycles.
From the gameplay perspective, Gran Turismo 5 will be using the PlayStation Eye for head-tracking. Moreover, you can set up the game to be displayed on three screens for multi-display if you have three PlayStation 3 systems lying around. Finally, the game will have Youtube HD uploading and 16-players online support.
Gran Turismo 5 is slated for a summer release on the PlayStation 3.
