2012 Indy Car weekend
The Izod Indy Car series comes to Sonoma for the eighth year in a row the weekend of August 24th-26th. Several changes pose new challenges for the teams this year as it is the first year the new cars and engines of the series will race at Sonoma. The Sonoma track has also undergone a reconfiguration of the racing surface. Three turns on the track, 7, 9, and 11 have been modified and will be used for the first time on a race weekend. Historic F1 Car races and SCCA World Challenge series cars will also take part in the racing action all three days.
