NASCAR Xfinity Series - Fixed - 2025 Season 4 Fixed

logo for NASCAR Xfinity Series - Fixed
2025 Season 4 Fixed - Races every odd 2 hours on the hour
The NASCAR iRacing Class B Series (Fixed Setup) features the NASCAR XFINITY Chevrolet Camaro, Ford Mustang, and Toyota Supra stock cars as raced in the NASCAR XFINITY Series, with multi-car fields running the same schedule of short, intermediate and speedway ovals as the "open" Class B series.

The series employs a fixed setup format, giving competitors the freedom to focus on their racing and strategic skills and eliminate concerns about chassis, aerodynamic and tire settings. Slightly narrower and with different aerodynamic characteristics compared to its Class A counterpart, the Class B cars are the perfect intermediate step between the NASCAR Craftsman Truck Series machinery and the Class A NASCAR Cup Series Next Gen cars.
