Kenseth drove the No. 17 Chevy. Kenseth won the last two races of the Busch season in 2006 driving the No. 17 Ford Fusion, at Phoenix and Homestead. In 2007, Kenseth planned to run 23 Busch race. Kenseth won the Stater Brothers 300 at California Speedway in February and the O'Reilly 300 at Texas Motor Speedway in April. Kenseth broke an 18 race winless streak as he won the 2008 Nicorette 300 at the Atlanta Motor Speedway. Kenseth's 23rd career series victory came after the series was renamed the Nationwide Series. On lap 104 at the 2009 Aaron 312 on April 25, Kenseth took a wild ride flipping over 3.5 times, sliding on his roof, then completed a fourth flip. The car burst into flames, and Kenseth walked away. Kenseth won the Diamond Hill Plywood 200 at Darlington Raceway in 2009. Kenseth led only the last four laps of the race – three of them under caution – after Busch had to pull into the pits due to a flat right-rear tire during the penultimate caution period and just as the race was about to get into a green-white-checkered finish. On May 28, 2011 Kenseth won the Top Gear 300 at Charlotte. Kenseth, filling in for Trevor Bayne, passed Roush Fenway teammate Carl Edwards with two laps to go to win his only Nationwide Start of the 2011 season. In 2013, Kenseth returned to the Nationwide Series for 16 races driving Joe Gibbs Racing's No. 18 Toyota. Kenseth finished with 7 top-five and 14 top-ten finishes. He won the summer race in Daytona and the fall race in Kansas. In 2014, Kenseth drove in 19 races in the No. 20, with 10 top-five and 15 top-ten finishes. He won the last race of the year at Homestead. Kenseth's first Winston Cup series race attempt came at Talladega in May 1998. Jack Roush of Roush Racing was interested in hiring Kenseth and the rest of the Reiser team, so he had Kenseth attempt Talladega in the No. 60 Ford. However this was a sixth entry for Roush in the race, and did not have a powerful enough engine to make the field. Kenseth's next attempt was at Dover in 1998, when he filled in for Bill Elliott in his No. 94 Ford for Elliott-Marino Racing.
