Mario Andretti sure was proud Sunday as his 19-year-old son Marco won his first Indy race in Sonoma, California on the Infineon Raceway.

That was race number 13 of the season, just one more to go this year on ten percent ethanol before the big switch to 100 percent next year.

Meanwhile, Team Ethanol can be proud of Sunday’s race. Number 17 car driver Jeff Simmons was running in third place at one point during the race and finished the day in seventh – tying his top Indy Car Series finish this season in Nashville.

Last race of the season coming up on September 10 at Chicagoland Speedway.
