Michael Waltrip Racing

Michael Waltrip Racing Holdings LLC, doing business as Michael Waltrip Racing ("MWR"), was an American professional stock car racing team that last competed full-time in the NASCAR Sprint Cup Series. The company was as a 50–50 partnership between Robert Kauffman, the founder and managing partner of Fortress Investment Group, and two-time Daytona 500 winner Michael Waltrip, who first established the team in 1996 in the Busch Series (now Xfinity Series). The team was the first full-time three-car team to field Toyota Camrys when Toyota entered the Sprint Cup racing fold in 2007, before being joined by Joe Gibbs Racing in 2008. MWR was also the last original Toyota team in the Sprint Cup Series to still be in operation, as Bill Davis Racing and Red Bull Racing Team have both ceased operations.

The team last fielded the No. 15 Toyota Camry for Clint Bowyer and the No. 55 Camry for David Ragan. Brian Vickers would normally drive the No. 55, but repeated health problems including blood clotting forced him out for much of 2015. Development driver Brett Moffitt and team owner Waltrip have also competed in the car.
