Takuma Sato has revealed that a return to F1 was a possibility for the 2010 season before he elected to switch his racing activities to the IndyCar Series.

Sato was confirmed with the KV Racing Technology team last week for his first foray into IndyCar racing, and tested with the team at Sebring last week. Former KV racer EJ Viso also took part in the test as he seeks a return to the team for the upcoming season.

Sato had found himself without a drive in F1 following the collapse of Super Aguri in 2008 and missed out on the chance to return in 2009 despite testing with Toro Rosso prior to the start of the year.

The Red Bull owned team was also on the list of possible options for 2010 - along with Renault and Lotus - but having failed to secure a drive with a competitive team, the Japanese driver elected to look elsewhere.

"I was always dreaming of continuing in F1 but I wanted a competitive car," he told Reuters. "Being competitive was something I missed in the last few seasons. There were seats available - with Campos or USF1 - but I don't feel it was appropriate.

"The name is F1 but I can't see those cars being competitive."

Despite insisting he was excited about the new challenge ahead, Sato refused to rule out the possibility of returning to F1 in future, but only with a team that would be capable of fighting for the podium.

"That's the general idea," he added. "I was very close with Toro Rosso and Lotus and Renault but it's always something beyond your control. That's F1."
