Located in Las Vegas, NV, the Las Vegas Motor Speedway was opened in September 1996 by Ralph Englestad and William Benette. It was built on the site of the Las Vegas Speedrome, a road course and drag strip that opened in 1972. Englestad and Benette sold the speedway to Speedway Motorsports, Inc., owned by Bruton Smith, in 1998. The track was substantially reconfigured in 2006. Major motorsports events held at the track include the NASCAR Cup Series, the Pennzoil 400, and the NHRA World Finals.
