What is the name of NASCAR's premier series?

NASCAR’s premier series is the NASCAR Cup Series. It is the organization’s top-level stock-car championship and the series in which NASCAR awards its most prestigious season title.

The division has operated under several names during its history. It began in 1949 as the Strictly Stock Division, later became the Grand National Series, and carried corporate sponsorship names including Winston Cup and Sprint Cup. Since 2017, it has been known as the NASCAR Cup Series.

The Cup Series features the best-known NASCAR teams, drivers and races, including the Daytona 500. Its schedule includes events on superspeedways, intermediate ovals, short tracks and road courses, giving the championship a broader variety of venues than many people associate with stock-car racing.

The other options are important NASCAR divisions, but they are not the premier series. The Xfinity Series is generally the second tier, the Craftsman Truck Series is the top national truck division, and the ARCA Menards Series is a separate stock-car touring championship below NASCAR’s Cup level.
