just saw this on a blog, looks pretty cool, a 3d-tunnel racing game. more screenshots here : http://blog.mercedes-benz-passion.com/2010/01/iphone-app-fur-sls-amg-steht-kurz-vor-dem-launch/ and this is the tv-spot : http://www.sls-amg-special.com/ and btw really cool car coming soon....
That game looks so bad. The car is a 2D image that has been placed onto the tunnel, which is a background.
It's their promotion game for their new car sls amg (which costs about 180k), so one car. It seems thats it should be a new kind of racing experience. If you look at the tv spot (link above) you see what it means. Seems they have put some effort into this game, so really lookimg forward to it. The blog is only in german but try to translate via google or so and you will get the full description.
