Rubens Barrichello, KV racingRubens Barrichello extended his IndyCar test with KV Racing into a third day at Sebring on Wednesday.

The 39-year-old Formula 1 veteran was scheduled to finish his running on Tuesday. But he stayed on to run on Wednesday morning, before handing over to KV's lead driver Tony Kanaan for the afternoon session.

"It was a really good morning," said Barrichello, who managed another 57 laps to take his total running to 334 miles over the three days. "I was able to do a lot of laps in Tony's car and very happy to be in the No. 11 – it's been my favorite number all my life."

The Brazilian explained that he decided to stay on at Sebring, having canceled an appointment in his home country, to make up for a lack of track time on Tuesday.

"The small amount of laps I did yesterday was compensated today and I want to thank the team again for letting me return," he added. "I think my feedback will be very beneficial to Tony and the whole team and I'm satisfied with what we have achieved. I leave Sebring with a good taste in my mouth."
