Arrow McLaren’s Pato O’Ward was the fastest driver throughout most of the second and final day of NTT IndyCar Series preseason testing at Sebring International Raceway, but he was supplanted by Team Penske’s Will Power who looked like he’d hold onto the top spot until Andretti Global’s Marcus Ericsson shot to P1 with the No. 28 Honda in the final minutes of the afternoon session.

The Swede’s 51.951s lap also served as the fastest across both days, which had his former teammate Alex Palou and the Chip Ganassi Racing team in charge on Monday with a 52.088s lap in the No. 10 Honda.

“It was super-positive,” Ericsson told RACER. “It’s only testing for sure, but I think the main thing for me is the whole winter, every time I’ve been in the car, all the work the Andretti team put in in the winter… I feel like they made some good steps on the package. We’re fast, there’s no doubt about it.
