The Kobalt Tools 400 is a NASCAR Sprint Cup Series stock car race held annually at Las Vegas Motor Speedway in Las Vegas, Nevada. The inaugural race was first held in 1998. For several years, the race was sponsored by United Auto Workers and DaimlerChrysler. From its inception through 2008, the race was run at a distance of 400 miles (640 km).[citation needed]The race is unique for its championship belt offered instead of a traditional trophy, owing to the city's "fight capital of the world" image. The race was also part of theNo Bull 5 challenge from 1999 to 2002.From 2001 until 2008, this race carried sponsorship from Chrysler. For the first six of those years, the race was known as the UAW-DaimlerChrysler 400 to reflect Chrysler's partnership with then-DaimlerBenz. After Daimler sold Chrysler to Cerberus Capital Management, the race became known as the UAW-Dodge 400 for 2008. Carroll Shelby International took over as sponsor for 2009 and 2010, with the 2009 race adding 27 miles (43 km) as part of the sponsorship in honor of the Shelby 427 Cobra. The 2010 race was known as the Shelby American.Lowe's, through its Kobalt Tools subsidiary, becomes the race's title sponsor for 2011; Kobalt was title sponsor for the spring race at Atlanta until the track gave up its early season date after 2010.
