Codemasters has announced that a playable demo of the Xbox 360 version of Race Driver: GRID is now available via Xbox LIVE. The demo offers 3 events to compete in. The eBay Motors Muscle Cup sees you taking the wheel of a ford Mustang GT-R and the streets of San Francisco, the Advan International Trophy hands you a Nissan S15 Silvia and your playground is Yokohama Docks, and the Euro Touring Car Series provides some old-school tin-top thrills with a BMW 320si touring car and the sweeping curves and hairpins of Jarama. Codemasters informed us that the PC demo will not be released today. Three new screenshots from the demo have been uploaded in our gallery.
