Sebring International Raceway is located on the former Hendricks Field, a United States Army Air Forces Combat Crew Training facility that was constructed in 1940. Pilots used Hendricks Field to train on B-17s throughout World War II.
The field was deactivated on Dec. 31, 1945 and given to the city of Sebring in 1946. The first race was staged at the facility in 1950.
INDYCAR SERIES QUOTES:
TONY KANAAN (No. 11 Andretti Green Racing): "We're testing a lot of things. We're trying big, big things that we did some simulation over the winter and thought were better. Changing big things in the car, that takes an hour, sometimes two hours. This is the time to do it, because we won't have time when we get to St. Pete. It's the last two days, now it's down to one day, before the season starts and before we go to St. Pete. I would say it's going well."
MARCO ANDRETTI (No. 26 Andretti Green Racing): "(Today was) not as great as we would like. We still have to work on gaining overall mechanical grip. However, we're doing a true test. If we can find some mechanical grip and balance tomorrow, I think we're going to be happy."
RHR: “We’re not tuning our car to the Sebring track like some of these teams are, but yet we’ve still come out and put up a pretty good time, which shows us that things are going well," Hunter-Reay said. “We’re being disciplined in our approach and working on things specific to St. Pete and those should pay off for us there."
Bobby Rahal: “It was a good day, we chunked through most of our test program, worked on some macro changes on the first day and will go from there," said team co-owner Bobby Rahal. “It’s our first day with the new paddle shifters and it seemed to work pretty well. We got through what we needed to do, and it leaves us plenty of room to build on it tomorrow."
