As for his fledgling
IndyCar career, Barrichello has previously told interviewers that he would be back in the US open wheel championship in 2013 - but cast doubt on whether it would be with the same team that he made his debut with, KV Racing Technology, alongside his close friend Tony Kanaan.
"I'm negotiating with a few teams but it's still too early to know what's going to happen," said Barrichello about his
IndyCar plans.
Given his long-time links with Honda, there have been rumours that he might move to the leading Chip Ganassi Racing squad, the engine manufacturer's flagship partner team in the series. Another option is the Schmidt-Hamilton Motorsports team which boosted French sportscar star Simon Pagenaud into fifth place in this year's driver standings in his rookie season.
Barrichello has also been trying his hand at stock car racing in Brazil after the end of this year's
IndyCar season, racing for prize money to go to the children's charity he runs with Kanaan, and Barrichello indicated that he he was torn as to which type of racing he was enjoying the most this year.
"We are negotiating with Indy and Stock," he told
ESPN. "I don't know for sure which was my heart is calling."
