There are more details surrounding the release of the Forza 4 demo, which is due to be released to Xbox Live subscribers on October 3rd. Apparently, Turn 10 has chosen two race modes for the demo, which are the Quick Race and Rivals modes.

While the Quick Race isn’t really anything new, the Rivals mode really is nothing more than Turn 10’s version of what we have seen Electronic Arts do recently with the Autolog technology in recent racing game releases. In a nutshell, the Rivals mode allows you to race against friends even if they are not online, with the system keeping track of completed challenges and races; this allows players to receive Bounty when you are able to beat opponents.

The demo will include a number of cars. The majority of these cars are the same cars that were seen at the E3 demo in 2011. The demo will include the 1970 Mercury Cougar Eliminator, 2011 Subaru WRX STI and the Ferrari 599 GTO. The demo track is apparently based on the Bernese Alps track, according to Turn 10.

Forza 4 is still slated for release on October 14th for the Xbox 360. The game will be released in both a standard and Limited Edition. If you elect to pre-order the game before release of the game, depending on where you pre-order it (Amazon.com/Best Buy/Game Stop/Microsoft Store/Wal-Mart) you will also get a special bonus unlockable car as a pre-order bonus.
