Forza Horizon launches on the Xbox 360 October 23, but a few weeks before then you'll be able to get behind the wheel early with a demo on October 9. Available free to Xbox Live Gold subscribers for the first week and everyone else after, the Forza Horizon demo will feature a few missions, several of which will be Rivals mode-compatible - you'll be able to compare demo deeds with your Xbox Live friends.

A section of Forza Horizon's sandbox map will be unlocked in the demo and all those who download then purchase the game on October 23 will get a custom 2013 SRT Viper GTS "designed to highlight Forza Horizon's 'gone-gold' status."
