ESCA was formed on August 3, 1963 in Santa Rosa, CA. Our purpose is to: encourage, present, and participate in sports car events, and exhibitions; encourage safe and sportsman like conduct on public roads; exchange technical information on engine performance and handling; and meet other sports car enthusiasts.
Read the revised 2020 ESCA Constitution:
ESCA membership is required to be on the site and you must also be 16 years of age or older.
Autocrossing is a low speed, timed event that is safe, challenging and fun. A course usually includes a combination of straight-aways, S-turns, and sweeping turns and is outlined with pylons. One entrant at a time is given a practice lap and one or more timed laps during which he tries to go as fast as possible without hitting any pylons. Autocrossing gives the driver a chance to learn better driving skills as well as respect for a well maintained, good handling automobile. ESCA presents several autocrosses each year.
All Auto-Cross Events are for ESCA members only and the site is not open to the public.
Due to limited space at the auto-cross site, all drivers must be a registered ESCA member.

See Rallye on this website for more details.
A rallye is jokingly referred to as the longest distance between two points. In a variety rallye, participants are given a set of instructions for a route several miles long. It is a test of the ability of the driver and navigator to follow those instructions as they travel on the roads looking for signs and situations that fit the definitions of the rallye. A rallye is not a speed event. ESCA sponsors the annual April Fool’s Rallye which is open to the public as well as several others for the enjoyment of the club members. Several of ESCA’s rallies have won the N.C.S.C.C. Variety Rally of the Year Award.
Tours are casual club events, drives planned along scenic routes or to places of interest. These usually take place on weekends, however, we do have some overnight tours to special activities and events. Recent tours include trips through the wine country, to the Infineon Raceway Classic Car Races, and to restaurants.
Each year we have a summer party and a Christmas party. Other activities have included potluck dinners, cruises, and picnics.
1st and 3rd Tuesdays of each month at 7 pm.
