context_page_description: Stewart-Haas Racing is an American professional stock car racing team that currently competes in the NASCAR Cup Series, the NASCAR Xfinity Series, the NASCAR K&N Pro Series West and eNASCAR Coca-Cola iRacing Series. The team is co-owned by three-time NASCAR Cup Series champion Tony Stewart and Haas Automation founder Gene Haas. It was founded in 2002 as Haas CNC Racing after Haas, whose company was a sponsor of Hendrick Motorsports, elected to form his own team. In 2009, Stewart, who had been driving for Joe Gibbs Racing, made a deal with Haas to drive for the team and in return receive a 50% stake in it.
  The team is based and headquartered in Kannapolis, North Carolina – roughly 10 miles north of Charlotte Motor Speedway – alongside sister team and Formula One entrant Haas F1 Team, but the two teams are treated as separate bodies for legal reasons.
  In the NASCAR Cup Series, Stewart-Haas Racing currently fields four Ford Mustang GT teams: the No. 4 for Kevin Harvick, the No. 10 for Aric Almirola, the No. 14 for Clint Bowyer, and the No. 41 for Cole Custer. In the Xfinity Series, the team currently fields the Ford Mustang full-time for Chase Briscoe.
context_section_description: Jack Sprague (2002–2003)
  What is now the No. 4 car was Haas CNC Racing's original foray into NASCAR's top series, with driver Jack Sprague and sponsor NetZero. Haas' car became the No. 0 Pontiac. Sprague posted a career-best 14th-place finish at the 2003 Daytona 500 to open up the season. Afterwards, however, the team began to struggle. After finishing 40th at Chicagoland, Haas released Sprague in favor of John Andretti, who finished 41st at New Hampshire and 33rd at Pocono, before qualifying 15th and finishing 19th at Watkins Glen. Because Andretti had a prior commitment with Dale Earnhardt, Inc., Jason Leffler drove the car at the Brickyard 400, finishing 33rd. Leffler lost his ride with Ultra Motorsports, where he drove the No. 2 truck in the Craftsman Truck Series, because of his start at Indianapolis, but Haas hired him to drive the car on a more permanent basis shortly thereafter.
  Ward Burton (2003–2004)
  Ward Burton was signed to drive the car toward the end of the 2003 season after eight years with Bill Davis Racing, while Leffler was reassigned to the Busch Series to drive the No. 00 car. In the final four races, he finished 13th at Atlanta and 18th at Rockingham.
  In the 2004 off-season, Pontiac announced it was leaving the sport, forcing the team to switch back to Chevrolet. Burton began 2004 by finishing 17th at the Daytona 500 and then earned the team's first top-10 finish the next week with a 9th-place finish at Rockingham. The team was also 9th place in points. Despite top-20 finishes in two of the next three races, the team began to slip in points. After a streak of bad races, the team re-emerged at California with a 10th-place finish. The team racked up five straight top-20 finishes and Burton earned outside pole at the Brickyard 400, but made contact early in the race and finally crashed to a 39th-place finish. In October, Burton finished again in 10th place, this time at Talladega. After finishing 40th at Phoenix, Burton was released by Haas and was replaced by Mike Bliss. The 2002 NASCAR Craftsman Truck Series champion took over and had an immediate impact finishing 10th at Darlington, leading Haas to sign him for the 2005 season.
  Mike Bliss (2004–2005)
  The team picked up Best Buy as an associate sponsor and four-race primary sponsor for 2005. The U.S. Coast Guard, sponsor for Haas CNC's Busch Series Car, also sponsored one race. Bliss began the 2005 season by finishing 18th in each of the first four races. Despite finishing ninth at Pocono and 7th at Bristol, he was released from the ride at season's end.
  Jeff Green (2006–2007)
  In the off-season, Jeff Green was signed to replace Bliss. Best Buy became the primary sponsor as NetZero left, and the team began the 2006 season with a renumbered No. 66 Chevrolet. The new car number was in honor of the year the new primary sponsor opened its first store, 1966. Green finished 28th in the final point standings in 2006, and was signed to continue driving the No. 66 in 2007. On October 22, 2007 it was announced that Jeremy Mayfield would take over the No. 66 car for Green for the final four races of 2007. During the off-season, Best Buy moved to Gillett Evernham Motorsports to sponsor Elliott Sadler's No. 19 Dodge.
  Scott Riggs (2008)
  Former Evernham driver Scott Riggs took over the No. 66 in 2008 with State Water Heaters as the sponsor, coming over from Morgan–McClure Motorsports. Hunt Brothers Pizza and Haas Automation also appeared on the car. Riggs struggled early on, but his performance picked up following the announcement of Tony Stewart as the new co-owner of the team in mid-summer. Riggs finished the season in the top 35, but was released in favor of Ryan Newman who had just departed from Penske Racing. With Newman driving, the car changed numbers to No. 39, which was Newman's midget car number. The U.S. Army signed on to sponsor the car alongside State Water Heaters and Haas Automation, but Hunt Brothers moved to JR Motorsports in the Nationwide Series.
  Ryan Newman (2009–2013)
  During the 2009 season, Newman led the first 25 laps at Bristol and finished se
