Michael Waltrip Racing

Michael Waltrip Racing began racing in the Winston Cup Series in 2002, making its debut at the 2002 Aaron's 499. The car was the No. 98 Aaron's Chevrolet Monte Carlo driven by Kenny Wallace. Wallace qualified 27th and finished 21st. Following that first race, Waltrip sold the No. 98 and its owner points to Innovative Motorsports.

After that, MWR fielded one Cup Series car, the No. 00, on an intermittent basis through 2005. In 2006, MWR, in partnership with Bill Davis Racing, added a second car, Waltrip's No. 55, but neither car had manufacturer support due to DaimlerChrysler suing BDR for breach of contract.

In 2006, MWR signed an agreement with Toyota to field multiple Toyota Camrys in the Nextel Cup Series for 2007. Waltrip was then able to add a third car driven by Dale Jarrett to his team for 2007, along with new sponsors.

However, the MWR team had a disastrous season. In February, Waltrip's teams were disallowed from their starting spots in the Daytona 500 due to an illegal fuel additive. The team members each faced a $100,000 fine and many team members were suspended. Though they backed up their qualifications by using back-up cars they suffered a terrible year. The team was unable to recover, failing to qualify for many events and losing sponsors such as Burger King and Domino's Pizza. Waltrip partnered with British-American billionaire Rob Kauffman as a 50% co-owner in order to fix the problem.

After the season, an ugly controversy emerged with Jack Roush of Roush Fenway Racing, who accused MWR of stealing one of his team's sway bars after a September 2007 race. While Waltrip and some other drivers, such as Jeff Gordon, argued that parts are often inadvertently swapped during post-race inspection, Roush held a lengthy news conference in March 2008 to accuse "the non-descript Toyota team" (MWR) of deliberately stealing the bar and threatened legal action. However, Roush, who had previously accused Toyota teams of being "ankle-biting Chihuahuas" and brought up Pearl Harbor in his effort to keep Toyota out of NASCAR, did not pursue such a lawsuit as NASCAR declared that the Toyota teams did nothing wrong and that Roush's ideas against Toyota were ridiculous.

For 2008, MWR once again added Aaron's as a sponsor and ran competitively, but again managed only one pole and just one top-5 finish, and UPS withdrew as a sponsor after Jarrett retired and transferred its sponsorship to MWR's archrivals Roush Fenway. In 2009, MWR was forced to form a technical alliance with JTG Daugherty Racing to have sponsorship for its third car. However, during this season, MWR finally achieved success as a Sprint Cup team, including winning a race and placing two cars in the top six two weeks later. Both of those cars ended up in the top 20 for the year. For 2010, MWR added Martin Truex Jr. as a full-time Sprint Cup driver. Michael Waltrip continued as a part-time driver, while also adding on talent such as former RCR crew chief Scott Miller, and hiring drivers Mark Martin, Clint Bowyer, and Brian Vickers.

In 2013, controversy arose in the Federated Auto Parts 400. Clint Bowyer spun out with seven laps to go, forcing a caution. Rumors abounded postrace that Bowyer had deliberately forced a caution to help Truex into the Chase. Truex was just ahead of Ryan Newman for the final Chase wildcard slot. They gained even further credence when it was revealed the third MWR driver, Brian Vickers, had pitted after the restart on orders from general manager Ty Norris, who was serving as his spotter. As it turned out, by the time Newman was able to pit, he lost several spots and ultimately finished third, tying him with Truex in points. However, Truex got the final wildcard spot in the Chase via a tiebreaker. An investigation was unable to turn up conclusive evidence that Bowyer's spin was deliberate, but did find that Norris had tried to manipulate the race and Chase standings by having Vickers pit. As a result, NASCAR issued some of the stiffest pena
