The IndyCar Series will continue to race at the Infineon Raceway until 2011 after an extension to the current deal was confirmed.
The high-speed Californian road course has been a popular venue since its introduction in 2005, playing host to some memorable races, particularly Marco Andretti's maiden win in 2006, a result that made him the then-youngest winner of a major open-wheel race.
Now, ahead of this year's PEAK Antifreeze & Motor Oil Indy Grand Prix of Sonoma County, it has been revealed that the Infineon Raceway will host races for the next three years.
"We're looking forward to building on the IndyCar Series tradition at Infineon Raceway," said Terry Angstadt, president of the commercial division of the Indy Racing League, sanctioning body for the IndyCar Series and Firestone Indy Lights.
"Technology and innovation are key attributes of the IndyCar Series, and Infineon Raceway provides an ideal venue in Northern California that is consistent with that branding and important to our continued growth and development."
Pointing out that the larger grid has sparked considerably more interest in the series recently, Infineon Raceway president and general manager Steve Page says it was an easy decision to extend the contract.
"This series has tremendous momentum, with larger fields, emerging new stars and terrific racing. The future of IndyCar racing is bright indeed and we're excited to see that future play out on the corners and straightaways of Infineon Raceway."
