NASCAR teams compete in all three national NASCAR series: the Cup Series, Xfinity Series, and Craftsman Truck Series, as well as in all the regional touring series.
A team is limited to four cars in each of the NASCAR series.
The team often shares a single manufacturer for all of the team's cars, but each car has an independent car number, driver, and crew chief.
