History
Originally, the category contested its races in small ovals and with compact cars equipped with V6 engines. It was only in the late 1960s that he began visiting superovals like Daytona, which used cars that had previously competed in the major division. In 1989, the regulations forced participants to use the same car models as the Copa. Engines were converted to V8s in the 1995 season; the gasoline stopped having lead on the second date of 2007. The 2007 season engines have carburettors, overhead camshafts, 5.8 liters of displacement and more than 650 hp of peak power (450 hp with restrictor plates). Starting in 2010, the "Car of Tomorrow" will begin to be rolled out, featuring a different silhouette than the NASCAR Cup Car of Tomorrow and a shorter wheelbase. The bodies correspond to the Chevrolet Camaro, Ford Mustang, Dodge Challenger and Toyota Camry.

In 2016, a playoff elimination system similar to the Chase for the SprintCup was implemented: the format consists of 12 drivers with two preliminary rounds of three races, where four drivers are eliminated after each cut. In this way, only four drivers reach the definition for the title in the final race, where the best placed driver wins the title. In each round the drivers' score is reset, and the winner of each race is automatically classified to the next round.

The category functions as a quarry for aspiring drivers to reach the NASCAR Cup Series, as a refuge for drivers who prefer shorter races, and as a method for the drivers of the main division to practice on the same track, since the dates are often shared. for both contests. Although NASCAR have created rules in recent years decrease the participation of regular drivers in the NASCAR Cup Series.


 * In 2011, NASCAR regulated that drivers can score points in one of the three national series (NASCAR Cup, Xfinity Series, or Trucks) in a season, and not score points in all three categories, as was before the implementation of this rule.
 * Starting in 2017, NASCAR Cup drivers with more than five years of series experience will be allowed to compete in a maximum of ten races in the Xfinity Series, but will not be able to participate in the postseason.

Recent circuits
Races typically last between 200 and 300 miles (320 and 480 km). Until 1990, the category visited mainly short ovals from the southern United States, but also medium ovals ( Charlotte and Darlington), superovals (Daytona), mixed circuits ( Road Atlanta), ovals of the Midwest (Indianapolis Raceway Park and Milwaukee Mile) and the Northeast (such as  Dover). Beginning in the 1990s, more medium ovals, super ovals, and the mixed circuits of Watkins Glen and Road America were added, as well as more ovals from the Midwest and Northeast, and ovals from the West Coast. such as Fontana,  Las Vegas and  Phoenix. In 2013 Mid-Ohio was added as part of the season schedule.

The first date outside the United States was at the Autódromo Hermanos Rodríguez, Mexico, held between 2005 and 2008, always on a mixed route. The category ran in the Gilles Villeneuve Circuit, Canada, between 2007 and 2012.
