NASCAR has one of the richest histories in the realm of motorsports. With more than 75 years of stock car racing and multiple series running under its banner, NASCAR has been a pioneer in this field. The top three National NASCAR Series are the Cup Series, Xfinity Series, and the Craftsman Truck Series. On the surface, all of the three series fall under the same umbrella but are very different at their core.

Difference between NASCAR Cup and Xfinity Series

One of the biggest differences between the Cup Series and the Xfinity Series is that the Cup Series is considered the top level of stock car racing with the Xfinity Series as a feeder series for the same.

Though most of the Xfinity grid is made of young drivers who wish to move up to the Cup Series, many veterans who compete in the Cup Series are also part-time drivers in the Xfinity Series. Another main difference is that during the race weekend, the Cup Series races are the main event of the weekend with the Xfinity and Truck Series races serving as the support races.

When it comes to the structure of the series, the playoffs structure of both the series is the same but instead of 16 drivers being promoted to the Round of 16 in the Cup Series, Xfinity only promotes 12 drivers further.

In the structural differences of cars, the wheelbase of Xfinity cars is slightly shorter by just five inches. The Cup Series cars have a wheelbase of 110 inches, whereas, the Xfinity Series cars have a wheelbase of 105 inches. The Xfinity cars are lighter and also carry less downforce than the Cup cars.
