NASCAR Xfinity Series Countdown

NASCAR Xfinity trivia

The NASCAR Xfinity Series is a stock car racing series organized by the National Association for Stock Car Auto Racing (NASCAR). It is considered as the second-highest level of professional stock car racing in the United States. Races are typically held on the same weekends as the NASCAR Cup Series and are driven on a mix of oval and road course tracks. The series features drivers competing in specially built race cars that are similar to those used in the Cup Series, but with less horsepower and downforce.
