Track Facts –

In 1968, a twisting 12-turn, 2.52-mile road course and a quarter-mile drag strip were carved into the rolling hills at the gateway to the Sonoma Wine Country. Since then, race fans have been treated to some of the greatest racing found anywhere in the world.

Whether it’s amateur or professional SCCA road races, AFM motorcycle racing, sports car events, vintage cars or the raw power of NASCAR, INDYCAR and NHRA drag races, Sonoma Raceway has played host to some of racing’s top events and its greatest moments.

Racing stars such as Mario Andretti, Dale Earnhardt, Jeff Gordon, Al Unser, Dan Gurney, Kenny Roberts, Shirley Muldowney, Don “The Snake” Prudhomme and John Force have all left their indelible marks at this unique and historic facility.

It is arguably the world’s busiest racing facility, with track activity scheduled an average of 340 days a year. It is one of North America’s most complete and versatile motorsports complexes and home to one of the nation’s only high-performance automotive industrial parks with approximately 75 tenants.

The Toyota/Save Mart 350 Monster Energy Cup Series weekend highlights the raceway’s diverse motor-racing schedule. In addition to NASCAR, the busy summer schedule will also include the NHRA Mello Yello Drag Racing Series, Verizon IndyCar® Series season finale MotoAmerica Series and the SCCA National Championship Runoffs.

Track Facts & History
• The Sonoma Raceway road course features more than 160 feet of elevation change from its highest point (Turn 3a, 174 feet) to its lowest point (Turn 10, 14 feet).

• The berms on the turns of the road course are painted blue and gold at the suggestion of raceway President and General Manager Steve Page, who attended UC Berkeley.

• The property on which the raceway was built was a working farm called Sears Point Farm in the early 1900s.

• The raceway houses a motorsports industrial park of more than 70 businesses in 104 shops.

• In 2011, in a partnership with Panasonic Corporation of North America, the raceway completed a solar installation of nearly 1,700 solar panels, which offsets approximately 41% of the raceway’s energy usage.

• Drivers who complete the Toyota/Save Mart 350 Monster Energy NASCAR Cup Series race will make 1,100 turns around the road course. The race spans 110 laps.

• The NASCAR configuration of the Sonoma Raceway road course is lined with 1,000 tire packs made up of 25,000 tires, 90,000 screws, 90,000 clips and 180,000 washers.

• Mat Mladin (AMA), Josh Hayes (AMA), Doug Kalitta (NHRA, Top Fuel), John Force (NHRA, Funny Car) and Jeff Gordon (NASCAR) are the only riders/drivers to three-peat in a major racing series in Sonoma.

• Nearly 4,000 sheep, housed at the raceway and provided by Rocky Mountain Wooly Weeders, provide natural land care, helping to maintain the facility’s grasses and fire lanes.

• Winners in Sonoma celebrate with a sip from the Champion’s Goblet in Sunoco Victory Lane. The goblet, which is handcrafted by a local glass blower from Sonoma, was introduced in 2006 and incorporates the raceway’s rich wine country heritage.

• The raceway has collected more than 475 tons of materials (950,110 pounds) since the inception of its recycling program in 2004.

• Through the Track Ambassador program, the raceway engages approximately 300 volunteers to help around the facility during event weekends and at various promotional and charitable activities throughout the year.

• The raceway donated 8,045 event tickets valued at more than $418,356 to Northern California non-profit organizations in 2014.

• Levy Restaurants partnered with 14 local non-profits who worked in concession stands during event weekends in 2014. These groups received more than $76,000 for their efforts.

• Sonoma Raceway is home to 15 owl boxes, which encourage owls to nest and help with natural rodent mitigation.


The Wall of Fame is designed to honor those who have excelled not only in their form of motor racing, but more importantly, in Sonoma. Each inductee is recognized during a ceremony with a marble plaque engraved with his/her likeness. All of the plaques are placed onto the Wall of Fame, which is located behind the main grandstand.

The Wall of Fame includes competitors from all forms of motor racing featured in Sonoma, including NASCAR, NHRA, AMA, open-wheel cars, sports cars and more. It will also include those who have made significant contributions to the raceway over the years. A raceway committee oversees the selection process on an annual basis.
