Max Chilton kept Carlin at the top of the timesheets on the second day of unofficial IndyCar testing at Sebring.
Chilton, the only driver so far confirmed for the team this season, joined late arrival Felipe Nasr on track on Tuesday, bettering his team-mate by 0.062s with a best time of 52.113s.
As on Monday, the 13 drivers in taking part on Tuesday ran on a shortened 1.7-mile version of the famed sportscar course that allows teams to simulate the street circuit in nearby St Petersburg that will open the IndyCar season next week.
Rookie Rinus VeeKay was fourth fastest for Ed Carpenter Racing, ahead of reigning series champion Josef Newgarden with Patricio O’Ward completing the top-five fastest runners.
Simon Pagenaud was sixth fastest, ahead of Conor Daly, Will Power, and Oliver Askew.
Most of the drivers taking part in Tuesday’s test were Chevrolet runners, with Rahal Letterman Lanigan duo Graham Rahal and Takuma Sato the only Honda drivers in attendance on the second day.
Rahal turned the 10th fastest time, ahead of Dalton Kellett and Sato, with Ben Hanley of DragonSpeed once again rounding out the runners – but within 1.2s of Chilton’s pacesetting time.
While Carlin was once again fastest, it was Daly and O’Ward of Ed Carpenter Racing and Arrow McLaren SP respectively that led the day in terms of laps run, completing 140 circuits each over the course of the day.
After participating on Monday, Andretti Autosport, its satellite teams, and Chip Ganassi Racing were not present for the Tuesday running.
