The NASCAR Cup Series is the highest level of racing in NASCAR. Drivers race in 36 races a year, and the driver with the most points at the end of the year is awarded the NASCAR Cup. The closest championship battle was in 2011, and was won by Tony Stewart, who finished the season tied in driver points with Carl Edwards. Stewart won the Cup with five race wins on the season to Edwards' one. This ended a streak of five Sprint Cup wins by Jimmie Johnson. Kyle Busch was the 2019 Cup Series champion. It was his second championship. He won his first championship in 2015.
