The demo is a drag race that's very similar to the drag racing mode found in the Need for Speed Underground games, but unlike those games, you'll have full steering control over your car instead of just switching lanes at the tap of the controller. The demo puts you behind the wheel of a tricked-out BMW and puts you on a short stretch of road. You'll have to weave your way through pretty heavy traffic to win. You'll even get the opportunity to drive right under the trailer of a big rig. If you don't make it under fast, the logs on the back of a truck spill out, blocking even more of the track.
