i think its xbox - original.........i havnt seen it on the list for 360 games. They do have an offroad style rally game that looked amazing scenary wise but i dont think its got licensed cars. Collin Mcrae is usally on xbox.
i dont think its a screen shot... i got it from http://www.gamewallpapers.com/ ... they make most of the displayed wallpapers using promotional material for various games... they got some real cool ones... most are free... they allow 5 free previews and 2 free downloads per day
Its a render. Although the 360 should be capable of producing near the same. (if good AA processing).
