Eleven Verizon IndyCar Series drivers, including the top three in the championship standings, completed a one-day test session at Sonoma Raceway on Aug. 7.

A total of five teams tested the 12-turn, 2.38-mile road course in preparation for the GoPro Grand Prix of Sonoma on Aug. 22-24 -- the penultimate race of the season. It marked the final test scheduled for Sonoma before race weekend.

Participants included Team Penske drivers Helio Castroneves, Will Power and Juan Pablo Montoya, Target Chip Ganassi Racing’s Scott Dixon and Tony Kanaan, as well as reigning Indianapolis 500 winner Ryan Hunter-Reay (Andretti Autosport) and Sunoco Rookie of the Year points leaders Carlos Munoz (Andretti Autosport).

“Driving a Verizon IndyCar here is a rush. There’s really no comparison to driving a stock car here,” said Montoya, who claimed his first Sprint Cup Series victory in Sonoma in 2007. “It takes a lot of cojones to run an IndyCar here, particularly through the Esses and Turns 3/3a.”

Other participating drivers included Graham Rahal (Rahal Letterman Lanigan Racing), Charlie Kimball (Novo Nordisk Chip Ganassi Racing), Ryan Briscoe (NTT DATA Chip Ganassi Racing) and Josef Newgarden (Sarah Fisher Hartman Racing).

“I love this track. It’s very unique with its massive elevation changes, and it’s a lot of fun,” said Briscoe, who in 2012 posted one of Team Penske’s five wins at Sonoma Raceway. “It’s got its challenges, though. You put new tires on and they last for about three laps with this track surface, so a big key to being good here is the consistency of the car.”
