List of NASCAR Xfinity Series champions
The NASCAR Xfinity Series Drivers' Championship is awarded by the chairman in NASCAR to the most successful Xfinity Series racing car driver over a season, as determined by a points system based on race results. The Drivers' Championship was first awarded in 1982, to Jack Ingram. The first driver to win multiple Championships was Sam Ard in 1983 and 1984. The current Drivers' Champion is Tyler Reddick who won his first NASCAR Xfinity Series championship in 2018.
As of the 2016 season, the Championship has been decided using NASCAR’s “Playoff” system. 12 drivers qualify for the Playoffs; race winners are automatically locked in and the remainder is set by the highest non-winners in the points standings. Drivers can accumulate points that carry into the playoffs by winning a stage or the race itself (1 playoff point for a stage win, 5 playoff points for a race win). After qualifying for the Playoffs, drivers have their points reset to a significantly higher total than non-Playoff drivers, with bonus points added appropriately for stage and race wins. This method is also used for eliminating drivers who qualified for the Playoffs but didn’t advance into the next round. The Xfinity Series Playoffs start with 12 drivers in the Round of 12, then cut off the lowest 4 non-winners in the points standings after 3 races. This process is repeated with the remaining drivers for the Round of 8, leaving 4 drivers still eligible to win the championship that season. Following the Round of 8, all previously accumulated playoff points are reset, leaving the “Championship 4” drivers all with an equal opportunity to win the championship in the 1-race final round at Homestead–Miami Speedway. Stage points also do not count for Playoff drivers in the final race. The highest-finishing driver out of the Championship 4 is then declared the champion.
Overall, twenty-eight different drivers have won the Championship, with Sam Ard, Jack Ingram, Larry Pearson, Randy LaJoie, Dale Earnhardt Jr., Kevin Harvick, Martin Truex Jr., and Ricky Stenhouse Jr. holding the record for most titles, at two. Ard, Pearson, LaJoie, Earnhardt Jr., Truex Jr., and Stenhouse Jr. all have the record for most consecutive Drivers' Championships, with two consecutive championships.
