NASCAR iRacing Class B Series Series - 2025 Season 1

logo for NASCAR iRacing Class B Series
2025 Season 1 - Races every 2 hours on the hour
The NASCAR iRacing Class B Series 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 an open setup format, allowing competitors to squeeze those extra tenths out of their lap times with the right adjustments. 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.
