Graham Rahal believes that his switch to Rahal Letterman Lanigan for the 2013 has gotten off to an encouraging start after testing with the team for the first time on Tuesday.
Rahal completed 49 laps on Sebring's short course before thunderstorms brought the day to an early end, but he told IndyCar.com that his time with the team had still been productive.
"The car has been extremely good handling-wise; we're right up to speed," he said. "Lap times aren't as quick as they were in the spring because the track just doesn't have the grip, but that doesn't matter. We're here to learn, we've tested a lot of stuff and we're making the car better.
"A lot of these guys I've known for a long time, but it's the first test day I've ever worked with them and it's been fun to kind of plug away.
"We're still a long ways off from the season but we have extremely high hopes and that's what we're working toward. To get a head start, to get a few days here means a lot to all of us."
Several teams are scheduled to run at Sebring before the 2012 testing blackout comes into force on Friday.
Rahal was expected to remain in the car until Wednesday, with others including Penske duo Will Power and Helio Castroneves, 2012 champion Ryan Hunter-Reay, rookie of the year Simon Pagenaud, and KV Racing's Tony Kanaan and Simona de Silvestro all among the lineup due to run on Tuesday.
Several of those drivers will also test Wednesday, where they will be joined by the likes of Target Chip Ganassi's Scott Dixon, BHA's Bryan Herta and Andretti Autosport's James Hinchcliffe.
Conor Daly and Tristan Vautier are also slated to have their first run in an IndyCar on Wednesday for A.J. Foyt Racing and Schmidt Hamilton, respectively.
