It's the ninth win overall for Kanaan and Barrichello in the event, which was formerly known as the Granja Viana 500.
"Two 500 miles races in a year, that's pretty good," Kanaan said after revealing his image on the Borg-Warner Trophy at Indianapolis Motor Speedway.
"That go-kart race is always a tradition for us, but for the last five years we didn't win. This was the 17th time they've had the race and we've won nine, so that's not so bad. It was a special moment. All of our kids were there, so we all went to the podium."
