iRacing added the NASCAR Cup Gen 4 cars — the 2003 Chevrolet Monte Carlo and Ford Taurus — in March 2023 (2023 Season 2 build). This marked the arrival of an iconic era in NASCAR history, when horsepower was unrestricted, aerodynamics were evolving rapidly, and stock car racing was arguably at its most raw and unpredictable.
The Gen 4 cars fill a gap in iRacing’s oval lineup between the high-powered 1987 Cup machines and the modern Next Gen. With around 725 horsepower, big, heavy chassis, and aero-sensitive handling, they give sim racers the chance to relive an era of thunderous racing and nail-biting pack battles.
