2016 NASCAR Xfinity Series

The 2016 NASCAR Xfinity Series was the 35th season of the Xfinity Series, a stock car racing series sanctioned by the NASCAR in the United States. The season started at Daytona International Speedway on February 20 and ended at Homestead-Miami Speedway on November 19. Daniel Suárez of Joe Gibbs Racing won the championship, becoming the first non-American to win a title in NASCAR's top 3 divisions.

This was the first year that the Xfinity Series (and the Truck Series) had a playoff system. Just like in the Cup Series, four drivers competed for the title in the final race at Homestead, also the final round of the playoffs. Those drivers are shown below.

Rule changes
On January 19, NASCAR announced the introduction of a playoff format similar to the Chase for the Sprint Cup for the Xfinity Series and the Camping World Truck Series. After the 26-race regular season, the top-12 drivers will enter the Round of 12 (Kentucky, Dover and Charlotte), with championship points reset. The top-eight drivers will advance to the Round of 8 (Kansas, Texas and Phoenix). The top-four drivers will qualify to the Championship 4 at Homestead. Race winners will automatically advance to the next round. Additionally, the 16 drivers who qualified for the 2015 Chase for the Sprint Cup are ineligible to race at Homestead.

NASCAR also announced that Dash 4 Cash races would feature two heat races that determine the starting grid for the main event. If a driver is the highest finishing eligible driver in two of the races, they become eligible for the Xfinity Chase.
