Sonoma Raceway, a road course and dragstrip in Sonoma County, California, is known for its challenging 12-turn, hilly course. It hosts a variety of motorsports events, including NASCAR Cup Series, IndyCar Series, NHRA Mission Foods Drag Racing Series, and motorcycle races. The track is also popular for amateur racing events, particularly among Sports Car Club of America members. Located in the Sonoma Mountains, it offers scenic views and is easily accessible from San Francisco and Oakland.
"Little Fauss and Big Halsy," a motorcycle road racing film starring Michael J. Pollard and Robert Redford, premiered. The film's plot centers around Redford's character, Halsy, and his aspiration to conquer Sears Point Raceway, a testament to the track's prestige in the racing world.
From 1989 until 2001, Sonoma Raceway's pit road could only accommodate 34 pit stalls, leading to teams sharing stalls or utilizing the garage area during the Toyota/Save Mart 350 Cup Series race.
Released in 1991, "Bill Elliott's NASCAR Challenge" featured Sonoma Raceway, showcasing the track in a NASCAR-themed video game.
Prior to the 1994 NASCAR race, Sonoma Raceway introduced a makeshift auxiliary pit road inside Turn 11, dubbed "Gilligan's Island." The nine slowest qualifying cars were relegated to these stalls, putting them at a significant disadvantage.
Sonoma Raceway debuted in the world of racing video games with its inclusion in Papyrus's "NASCAR Racing" for PC, marking the start of its digital presence in racing simulations.
Allan McNish, driving an Audi R8, established the fastest official all-time track record on Sonoma Raceway's original Long Grand Prix Road Course during the 2000 Grand Prix of Sonoma qualifying, clocking in at 1:20.683.
This year marked the end of the pit lane constraints at Sonoma Raceway, which had been an issue since 1989. Teams no longer had to share pit stalls or use the garage area for pit stops.
Sonoma Raceway completed renovations in 2002, extending the main pit road up to the start-finish straight. This eliminated the need for "Gilligan's Island," which has not been used in any NASCAR race at the track since.
A new layout for motorcycles, measuring 2.320 miles (3.734 km) and featuring 12 turns, was unveiled at Sonoma Raceway. This layout, based on the full course, bypasses the "Chute" and parts of the "Esses" for a distinct racing experience.
In 2004, Sonoma Raceway underwent a significant expansion. The project included the addition of 64,000 hillside seats, 10,000 permanent grandstand seats, a new wastewater treatment facility, 100 acres of restored wetlands, permanent garages, additional retail space, a go-kart track, and a new drag strip. The expansion increased the venue's capacity to 102,000 during major events, up from the permanent seating capacity of 47,000.
INDYCAR began using a modified version of the Sonoma Raceway layout. This layout, skipping sections of the "Esses" and utilizing a hairpin turn (Turn 11a) near the drag strip control tower, was used by INDYCAR until 2011.
2011 marked the final year that INDYCAR utilized the modified layout at Sonoma Raceway, which they had been using since 2006.
Sonoma Raceway introduced the "Grand Prix layout," an FIA Grade 2 variant, which was adopted by INDYCAR from 2012 to 2018. This layout features a Magny Cours-style hairpin, a widened Turn 9A, and a new Turn 11B designed for overtaking.
This year marked the final time INDYCAR raced on the Grand Prix layout at Sonoma Raceway, concluding its usage since its introduction in 2012.
