From the Daily Mail:  Gallery: The cars are the stars in Forza Horizon

Forza Horizon Demo now available
Players can experience the fictional Colorado of Forza Horizon, driving a sampling of cars from Horizon’s stellar line-up across a variety of different event types – from Horizon Festival events taking place on the dusty dirt roads to a climactic street race that find players winding up, around, and over the architectural marvel that is the Finley Dam.

Players who download and play the Forza Horizon demo and then purchase and play the full game online will receive a specially designed 2013 SRT Viper GTS.

Furthermore, fans can interact with and follow the cars by using #EscapeTheGrid hashtag on Twitter. You can also vote for your favourite car on the XboxUK Facebook page. To learn more, visit www.xbox.com/forzahorizon starting 8th October.
