Sonoma Raceway, formerly Sears Point Raceway and Infineon Raceway is a 2.523 mile (4.06 km) road course and drag strip located on the landform known as Sears Point in the southern Sonoma Mountains near Sonoma, California. The road course features 12 turns on a hilly course with 160 feet of total elevation change.[1] It is host to one of only five national NASCAR races each year that are run on road courses (including two races at Watkins Glen International in Watkins Glen, New York and the Nationwide Series-only races at Mid-Ohio Sports Car Course in Lexington, Ohio and Road America in Elkhart Lake, Wisconsin). It is also host to the IZOD IndyCar 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. Riverside International was razed for residential and corporate development and a shopping mall.

In 2002, Sears Point Raceway was renamed after a corporate sponsor, Infineon Technologies. However, as with many renamings of sports complexes, many people still call it by its original name. (It was never affiliated with Sears, Roebuck, and Company, having been named for the nearby Sears Point Ranch founded in the 1850s by settler Franklin Sears.) On March 7, 2012, it was announced that Infineon would not renew their contract for naming rights when the deal expired in May, and the track management is looking for a new company to take over naming rights.[2] Until it can find a new corporate sponsor, the course is simply identifying itself as "Sonoma."
History[]
1968-1979[]
The 2.523-mile (4.06 km) road racing course was constructed on 720 acres (2.9 km2) by Marin County owners Robert Marshall Jr., an attorney from Point Reyes, and land developer Jim Coleman of Kentfield. The two conceived of the idea of a race track while on a hunting trip. The ground was broken in August 1968 and paving of the surface was completed in November. The first official event at Sears Point was an SCCA Enduro, held on December 1, 1968.
In 1969 the track was sold to Filmways Corp., a Los Angeles-based entertainment company for $4.5 million. In May 1970 the track was closed and became a tax shelter for Filmways after losses of $300,000 were reported. Hugh Harn of Belvedere and Parker Archer of Napa arranged to lease the track from Filmways in 1973. Owner and operator Bob Bondurant of the Bob Bondurant School of High-Performance
Driving and partner Bill Benck took over management and control of the leased raceway from Parker Archer and Hugh Harn in 1974. A few years later a group calling itself Black Mountain Inc., which included Bondurant, William J. Kolb of Del Mar and Howard Meister of Newport Beach, purchased the track from Filmways for a reported $1.5 million.
American Motorcycle Association national motocross races in the hills north of Turn 7 became popular with Bay Area fans but were phased out by the end of the decade because of rising insurance costs.
1980-2000[]
In 1981 Filmways regained ownership of the track after a financial dispute with Black Mountain group. Jack Williams (the 1964 NHRA top-fuel drag racing champion), Rick Betts and John Andersen purchased the track from Filmways at an auction for $800,000. The track was renamed Sears Point International Raceway. In 1985 the track was completely repaved, in part with funds donated from the "Pave the Point" fundraising campaign. The first shop spaces (buildings A, B, C, and D in the main paddock area) were built.
In 1986 Harvey "Skip" Berg of Tiburon, CA took control of the track and became a major stockholder in Brenda Raceway Corp., which controlled the track until 1996. Additional buildings constructed on the property brought shop space to more than 700,000 square feet during 1987. In addition, a five-year contract was signed with the National Hot Rod Association for the California Nationals. The NASCAR Winston Cup Series debuted at the raceway in 1989.
In 1994 more than $1 million was spent on a beautification project and construction of a 62 foot (19 m)-high, four-sided electronic lap leader board in the center of the road course. In the following years, a major $3 million renovation plan included VIP suites and a two-story driver's lounge/emergency medical facility. In 1995 Trans-Am and SportsCar races returned to Sears Point and the NASCAR Craftsman Truck Series was added to the major-events schedule. Owner "Skip" Berg sold the track to O. Bruton Smith, chairman of Speedway Motorsports, Inc. in November 1996.
Major renovations began at Sears Point Raceway in 1998 with the creation of "The Chute," an 890-foot high-speed stretch. The first-ever running of the American Le Mans Series took place at Sears Point in July of 1999. In 2000 Sears Point Raceway gained unanimous approval from the Sonoma County Board of Supervisors by a 5–0 vote to begin work on a $35 million Modernization Plan that included 64,000 Hillside Terrace seats, repaving of both the road course and drag strip and increased run-off around the entire track.
2000-present[]
After the turn of the millennium, Infineon Technologies bought the naming rights, renaming the course Infineon Raceway. In 2006, the Grand Prix of Sonoma was transferred to the Rolex Sports Car Series, who would limit it to Daytona Prototypes only for 2007-2008 before the event was discontinued altogether. Since 2010, however, the course has seen a mild resurgence, with the circuit becoming a sponsor for various events as well as hosting an increasing amount of international series, including the WTCC and the return of the SCCA World Challenge. The year 2012 saw the end of Infineon as the corporate sponsor, with the track renaming itself Sonoma Raceway.
Layouts[]
Sonoma Raceway
Full circuit[]
The standard, full-length road course at Sonoma Raceway is a 2.523 mile (4.06 km) 12-turn course. This course was utilized by most competitions through 1997. Many races, including the Grand Prix of Sonoma, currently use the full course. The course is noted for turns two and three, which are negative-camber or "off-camber" turns, with the inside of the turn higher than the outside. This provides a challenge for the driver, as turn two would normally have the drivers moving to the left side of the track.
The raceway also has a quarter-mile (400 m) dragstrip used for NHRA drag racing events. The drag strip was originally located on part of the front straightaway of the course. Track changes completed in 2002 separated the road course from the drag strip.[3]
The Sonoma Historic Motorsports Festival, an annual classic car racing event, uses the full circuit.
The Chute[]
The track was modified in 1998, adding the Chute, which bypassed turns 5 and 6 (the Carousel), shortening the course to 1.95 miles (3.14km). The Chute is only used for NASCAR events such as the Toyota/Save Mart 350, and was criticized by many drivers, who prefer the full layout. In 2001, it was replaced with the 70° turn, 4A bringing the track to its current dimensions of 1.99 miles (3.20 km).[4]
The Chute was built primarily for spectator visibility, to increase speeds, and improve competition for the stock cars, which are not necessarily groomed well for road course racing. However, it has been criticized for taking away a primary passing point, and some INDYCAR drivers believe eliminating The Chute and replacing it with a new hairpin at Turn 4A, then rejoining the track at Turn 5, would create a circuit with three passing zones (Turn 4, Turn 7, and Turn 11). Furthermore, the speeds of the current layout with The Chute have been slower than if the full configuration was used.
Modified course[]

Motorcycle course
Variations of Sonoma's circuits are often used. Motorcycles use a 2.22 mile (3.57 km), 12-turn course. It is based on the full layout and does not include the Chute. This layout, opened in 2003, skips the later section of the Esses (8A and 9) and the run from Turn 10 to Turn 11 (the hairpin), using instead Turn 11a as Turn 11 has no runoff. This hairpin is located just past the drag strip control tower and offers a fairly straight run to the start-finish line.
When the Pirelli World Challenge returned to Infineon Raceway in 2011, the modified course was used (as the series doubleheader was acting as a support event for the Indy race). During the broadcast, it was explained that the Indy course skips much of the high-speed esses due to the curving section from Turn 9 to 10 ending with no runoff, especially on the outside of the curved section (bordered by the drag strip), and precariously little runoff in the high-speed Turn 10.
Another factor in removing the hairpin is the fact that the turn is only visible from the garages or the bleachers behind the esses. This is due to grandstands built along the front straight that is also the drag strip's grandstands.
In some variants, the end of the dragstrip (instead of the Keyhole) is used to create a Magny Cours-style hairpin that joints the drag strip to Turn 7 to open an overtaking opportunity.
For the 2012 IndyCar race, the course was modified again. The Magny Cours-style hairpin in Turn 7 is being used to create a passing zone. Turn 9A (the chicane similar to Spa's new Bus Stop) is being widened by ten feet (~3 meters) to allow for more room. A new Turn 11B has been made, moving further past the drag strip tower (Motorcycle Turn 11), being lengthened by 200 feet (~61 meters) to create a passing zone (it is located just before the race logos painted in Turn 11), and is located where the drag strip staging area is located.
For the World Touring Car Championship race, the full configuration is being used, but with the bus stop replacing the esses.

Artistic presentations[]
In the 1970 motorcycle road racing film Little Fauss and Big Halsy, starring Michael J. Pollard and Robert Redford, Redford's character, Halsy, saw Sears Point as the brass ring in the world of racing, and the film was loosely based around that idea.
Sonoma has been featured in many racing video games, beginning with Papyrus's NASCAR Racing for the PC, released in 1994 and has been a frequent addition to NASCAR based games and more recently road course variations have appeared.
