It will be a BIG race weekend!  For the first time in series history, the Verizon IndyCar® Series championship will be decided on a road course, as the 2015 season comes to a close at the GoPro Grand Prix of Sonoma, Aug. 28-30.

The 11th annual Verizon IndyCar Series event at Sonoma Raceway will serve as the season finale for the 17-race 2015 schedule, marking the first time the wine country road course has concluded a major open-wheel series season. The series championship has come down to the last race each year since 2006, so a solid performance on the challenging circuit will be more important than ever.

About Sonoma Raceway: 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, AMA and 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 350 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 70 tenants.
