The Sonoma Raceway, initially released in iRacing as Infineon Raceway on December 11, 2009, enters the service as one of America’s most technical and demanding road courses. Built in the hills of Northern California’s wine country, Sonoma’s mix of elevation, blind entries, and tight racing lines creates an environment where precision and bravery go hand-in-hand.
In August 2012, the track was officially renamed Sonoma Raceway in iRacing, aligning with its real-world counterpart. Since then, it has been a staple in both NASCAR and sports car racing within the sim.
What makes Sonoma unique in iRacing
- Elevation drama: Over 160 feet of elevation changes across the lap.
- Multiple layouts: Cup, IndyCar, Historic, and Rallycross variants.
- Technical rhythm: Tight, flowing corners punish overdriving and reward finesse.
- NASCAR road course identity: Home of the Toyota/Save Mart 350.
- Challenging visibility: Blind crests and off-camber corners make every lap a mental workout.
Sonoma remains one of iRacing’s most iconic U.S. road racing venues, providing variety across oval, sports car, and open-wheel disciplines.
