History
This track was originally conceived as a novelty track for Larry H. Miller, owner of the NBA's Utah Jazz and various automobile dealerships in the area, to use as a personal playground, with a budget of about $5 million. Due to enormous local motorcycle and auto industry support the concept gradually grew into an $85 million plus project, one of a kind in the U.S. The track was designed by world-renowned track designer Alan Wilson. The kart track was opened in September 2005 and the large track was opened to the public on 1 April 2006 when APEXtrackdays ran the first motorcycle track day. In 2006, the track's first year of operation, it hosted the Utah Grand Prix with the American Le Mans Series, a Honda Summit of Speed AMA Superbike double-header event, and the Discount Tire Sunchaser, a nine-hour endurance race of the Rolex Sports Car Series. The Sunchaser was shortened to 1,000 km for 2007 and 2008, and to 250 miles for 2009 and 2010. The track is also host to a WERA Grand National motorcycle roadracing event and the regional motorcycle road racing series Masters of the Mountains, promoted by the Utah sport bike association. The facility was named Motorsports Facility of the Year on 8 November 2006 by the Professional Motorsport World Expo in Cologne, Germany. On 14 July 2007, the track hosted its first-ever NASCAR event with a NASCAR Camping World West Series race on the Outer Track. The series has visited Miller every year since then, having switched to the outer course. On 22 August 2007, Miller Motorsports Park announced a three-year deal to bring the FIM Superbike World Championship to the track; the Superbike World Championship will race at the track for the first time on 1 June 2008 with the AMA Superbike Championship. To avoid direct comparisons between World Superbike and AMA Superbike, and because of sponsorship issues, the two championships will race on different configurations of the circuit. World Superbike will use the Outer course, while AMA Superbike and its support classes will use the Full course. The American Le Mans Series and Rolex Sports Car Series did not return to the Utah Grand Prix for 2011, and a K&N Pro Series West race was substituted. It was also announced that AMA Superbike would return to the track in 2011 with World Superbike. The off-road racetrack hosted a round of the Lucas Oil Off Road Racing Series from 2010 to 2018, and is scheduled to return in 2020.
Ownership change
It was announced on May 8, 2015 that the Larry H. Miller Group of Companies would not renew the lease on the land in Tooele County, Utah on which the park sits. The last day of operation will be October 31, 2015. According to local news sources, as of July 17, 2015, there were several offers being considered by the Tooele County commissioners that would provide for the facility to continue operation. On October 13, 2015, Tooele County voted to approve the sale of Miller Motorsports Park to Mitime Investment and Development Group for $20 million. The track will be renamed, and known as Utah Motorsports Campus. Mitime officially took over the property on October 31, 2015. On December 17, 2015, an order filed in 3rd District Court vacated the sale of Miller Motorsports Park to Mitime Investment and Development Group, saying Tooele County shortchanged another bidder by unlawfully selling the property at a price significantly below fair market value. Two days later, Tooele County's commissioners said that the bidding for the purchase of the property would be reopened. On February 1, 2016, Mitime took over the management of the facility on behalf of Tooele County. This was a temporary agreement for 2016 while the county went through the process of selling the facility. In May 2016, there were pending legal challenges to the sale, but the facility opened for business as the Utah Motorsports Campus. In November 2018, the sale to Mitime was completed. Mitime is a subsidiary of the Geely Holding Group of China
