iRacing offers several variations of Sonoma, reflecting the track’s real-world flexibility.
Available Configurations
- NASCAR Cup Circuit (2.52 miles): The primary layout used in stock car racing, featuring the Carousel.
- NASCAR Cup Historic (short course): A shorter layout bypassing the Carousel, used in NASCAR from 1998–2018.
- IndyCar Configurations: Alternative chicanes and turn sequences used by open-wheel racing.
- Rallycross Layout: A dirt-and-asphalt mix that transforms Sonoma into a unique RX venue.
Characteristics
- Elevation challenge: Blind crests and steep drops make braking inconsistent.
- Track width: Narrow in places, making overtaking difficult outside of Turn 11.
- Surface grip: Mix of smooth asphalt and bumpy sections.
- Versatility: Equally suited to NASCAR, IndyCar, GT, and Rallycross events.
Sonoma is an American classic: technical, diverse, and punishing. Its multiple configurations make it a valuable addition for a wide range of iRacing series.
