In this demo you can race against a friend or against the computer. The Race Circuit mode ("career mode") is not available.
You can also only select the buggy or stadium truck, not the monster truck or baja bug, and each of the cars have only two available paint jobs. Most importantly there is no track selection because you can only drive the Under Construction track - 5 laps.
After the race (in either mode), some screens appear with what's available in the full version and the demo ends.
