Sonoma Raceway, formerly Sears Point Raceway and Infineon Raceway is a 2.52-mile road course and drag strip located on the landform known as Sears Point in the southern Sonoma Mountains in Sonoma, California, USA. The road course features 12 turns on a hilly course with 160 feet of total elevation change. It is host to one of only three Monster Energy NASCAR Cup Series races each year that are run on road courses. It is also host to the Verizon IndyCar Series, the NHRA Mello Yello Drag Racing Series, and several other auto races and motorcycle races such as the American Federation of Motorcyclists series. Sonoma Raceway continues to host amateur, or club racing events which may or may not be open to the general public. The largest such car club is the Sports Car Club of America.
With the closure of Riverside International Raceway in Riverside, California after the 1988 season, NASCAR, wanting a west coast road course event to replace it, chose the Sears Point facility.
