Sonoma, CA 95476History
Sonoma Raceway is one of two remaining road courses on the NASCAR Sprint Cup Series circuit and was the last of several which was added to the calendar. Watkins Glen International is the other road course the Series still visits annually.

Strategy at this track consists of braking, shifting and execution of right and left-hand turns at top speeds.

The Infineon Raceway complex consists of a 2.52-mile road course, the 1.99-mile road course and a quarter-mile drag strip.

Because the track configuration prevented the usual passing and side-by-side competition by stock cars, the course was reconfigured, and Turns 4 through 7 (the carousel and hairpin turn 7) were eliminated. A straightaway now starts at the top of the track’s highest point and runs downhill to what used to be Turn 7. This change allows competitors more opportunities for swapping positions.
