The Audi Sportscar Experience operates year-round from the Audi Forum Sonoma, located trackside at Turn 1 of Infineon Raceway in beautiful Sonoma Valley. Using a variety of vehicles from among the Audi R, RS, and S model lines, the Audi Sportscar Experience takes drivers through a rigorous, behind-the-wheel instructional driving program at one of the most exciting racing circuits in the world. With its 160-foot elevation changes, challenging corners and breathtaking scenery, the 2.5-mile Infineon course has been described aptly as a small Nurburgring.
