More than a dozen Ind🌌yCar Series drivers tested at Infineo🐓n Raceway this week in preparation for the PEAK Antifreeze & Motor Oil Indy Grand Prix of Sonoma County on August 24.

Among those testin🐻g was series points' leader Scott Dixon, who holds a 78-point advantage over Helio Ca♓stroneves with three races remaining.

"It's always nice to go back to a circuit where you've won," said Dixon, who won last year's rꦛace on the 12-turn circui♕t. "It's going to be a tough race, so it's nice to get some testing in."

While Dixon had the opportunity to turn some laps on the 2.245-mile course, Castroneves will have to rely o🌳n teammate Ryan Briscoe's assessment.

"You can't test during a race weekend, and you've got to come in with a plan and really go for it," said Briscoe, the pole winner at the track in 2005.🎃 "Qualifying is tough, and it's important to do consistent fast laps, and then we go racing. It's nice to get a day of testing in."

This marked the first🍎 large-scale test of the modified version ওof the road course that will be used by the IndyCar Series. Drivers now exit Turn 6 and go directly up the track's drag strip as opposed to veering left before the right-hander at Turn 7.

"I think you will see some new passing with this change," said Vitor Meira, who had a best finish of 💧third at Infineon in 2006.

"It's a to꧒ugh corn🎉er because you're going from the fastest section of the track to the slowest, but it should be good."

Other drivers who tested ✱included Marco Andretti, Townsend Bell, A.J. Foyt IV, Mario Moraes, Will Power, Marty Roth, Tomas Scheckter,🧸 and Oriol Servia among others.

Practice f🍌or the race begins August 22 with the 💫battle for the PEAK Motor Oil Pole Award slated for August 23.
