Grant Enfinger

In 2020, Enfinger broke a 28-race winless streak by winning the season-opener at Daytona over Jordan Anderson by 0.010 seconds in overtime, his 3rd career victory and 100th win for Ford in the Series.

In 2019, Enfinger clinched the NASCAR Gander Outdoors Truck Series Regular Season Championship following the Michigan race. He was eliminated from the playoffs at Las Vegas when he finished 31st after experiencing an engine failure that also plagued three other trucks. Ilmor, the manufacturer of the engines, took responsibility for the NT1 engines that suffered from severe detonation due to the combination of the high engine load condition combined with the extreme weather conditions in Las Vegas. Despite Ilmor's announcement, NASCAR denied ThorSport's request to reinstate Enfinger and Johnny Sauter into the playoffs. He finished 7th in the final points standings despite winning no races, with teammate Matt Crafton claiming his 3rd career Championship also with no wins.

In March 2019, Enfinger made his Michelin Pilot Challenge sports car debut at Sebring International Raceway, driving a Ford for Multimatic Motorsports alongside ThorSport Racing teammates Matt Crafton, Ben Rhodes, and Myatt Snider.

In 2018, ThorSport Racing switched to the Ford F-150. Enfinger scored his second career win at Las Vegas and finished fifth in the standings.

ThorSport Racing hired Enfinger to drive the No. 98 Toyota Tundra full-time in 2017. He finished 11th in the standings.

Enfinger got married on January 16, 2016, in Fairhope, Alabama.

Enfinger returned to the Truck Series in 2016, driving the No. 33 Chevrolet Silverado full-time for GMS Racing. He began the year off with a bang winning his first career pole for the NextEra Energy Resources 250 at Daytona, the season opener, he would finish 20th though in the race after being caught up in the "big one" with six laps to go of the race. He finished in the top 5 in the next race, at Atlanta. But, he was still demoted to a part-time role with the No. 24, and replaced by Kaz Grala and Ben Kennedy in the No. 33. Enfinger ran 5 races later in the season for Gallagher's No. 24 team. For the running of the Fred's 250 at Talladega, Enfinger would start 2nd and would run great all race long, leading the most laps and getting his first career Truck win. This proved to be Enfinger's last race for Gallagher, although he ran the last race of the season at Homestead with RBR Enterprises.

Enfinger won the season-opening race at Daytona again in 2015. After winning five additional races, he won his first ARCA championship at the end of the season.

2014 would start off in record fashion, with Enfinger winning the first 3 races of the season (Daytona, Mobile, and Salem). He would follow that up with a win at Elko for his 4th win of the season. Prior to the race at Lucas Oil Raceway in July, it was announced that Enfinger, who was second in points at the time, would be moving from the Team BCR Ford to GMS Racing, taking his No. 90 and sponsor Motor Honey with him. Allegiant Travel will provide additional sponsorship. Enfinger finished 4th in his first race for GMS at IRP, but crashed at Pocono with Frank Kimmel. The next race at Berlin Raceway, Enfinger dominated, leading 181 of 200 laps to win the Federated Auto Parts 200 and move within 25 points of the points leader Mason Mitchell. He would move within 20 points of the lead after winning at DuQuoin State Fairgrounds Racetrack, earning him the Bill France Four Crown Award.
