Grab the free Need for Speed ProStreet demo from Xbox LIVE® Marketplace and take the wheel for two of the four racing disciplines included in the full game. Test your skills in grip racing with a two-lap race against seven other opponents in the Nissan GT-R Prototype on the A-43 Interloop of Germany's Autobahn. Experience the all-new Speed Challenge mode with BMW's M3 E92 on the Nevada Highway. Finally, be among the first in the world to check out the all-new 2009 Nissan GT-R, which will be available (and automatically replace the GT-R Proto) on October 23, coinciding with the GT-R's unveiling at the 2007 Tokyo Motor Show.
