The daylong event was open to the public, which had the opportunity to interact with the drivers during the noontime break.
Franchitti posted the quickest lap at 1 minute, 17.2 seconds over the 12-turn, 2.303-mile road course. Kimball (1:17.4) and Rahal (1:17.5) followed, while Viso (1:17.80) and Kanaan (1:17.84) rounded out the top five. All times were reported by the drivers.
"I like this track very much," said Barrichello, who was sixth quickest (1:17.88). "It's very difficult with the blind apexes. It's good that I can test again, and every time I'm improving. A track like this is very good and it teaches me a lot."
04/10/12 Half of the field in the IZOD IndyCar Series tested Monday at Infineon Raceway in Sonoma, Calif., although only one of the series' two "power teams" realistically laid down the hammer. Unofficial timing saw three Chip Ganassi Racing drivers at the top – Dario Franchitti quickest at a 1:17.2 ahead of Charlie Kimball (1:17.4) and Graham Rahal (1:17.5) around the 2.3-mile circuit.
The KV Racing Technology trio also lapped in the 1:17s, with E.J. Viso at 1:17.80, Tony Kanaan at 1:17.84 and Rubens Barrichello at 1:17.88. Racer.com
