As drivers and crews brace for perhaps the warmest race of the 2025 NTT INDYCAR SERIES season, Felix Rosenqvist led the morning warmup Sunday for the XPEL Grand Prix of Road America Presented by AMR.

Rosenqvist was quickest in the 25-minute session with a lap of 1 minute, 45.0725 in the No. 60 SiriusXM Honda of Meyer Shank Racing w/Curb-Agajanian. Rosenqvist is starting 12th in the 55-lap race, which begins at 1:30 p.m. ET today (FOX, FOX Deportes, FOX Sports app, INDYCAR Radio Network).

Air temperatures reached the mid-80s by mid-morning in Wisconsin, with the heat expected to climb another 10 degrees by the time the green flag flies.

Rosenqvist wasn’t the only driver starting in the middle or back half of the 27-car field who found speed in the short session on the 14-turn, 4.014-mile natural terrain road course.

Six-time series champion Scott Dixon was second quickest at 1:45.1517 in the No. 9 PNC Bank Chip Ganassi Racing Honda. Dixon will need that speed, as he is starting 25th after incurring an interference penalty in NTT P1 Award qualifying Saturday.

Santino Ferrucci was third at 1:45.2402 in the No. 14 Sexton Properties/AJ Foyt Racing Chevrolet. Ferrucci is starting 18th. Colton Herta, starting 16th, climbed to fourth in the warmup at 1:45.2807 in the No. 26 Gainbridge Honda of Andretti Global.

Two-time Indianapolis 500 winner Josef Newgarden rounded out the top five at 1:45.3602 in the No. 2 PPG Team Penske Chevrolet. Newgarden qualified 10th, the only driver in the top five of the warmup results who will start in the first five rows of the grid.

NTT P1 Award winner Louis Foster ended up 27th on the time charts at 1:47.6275 in the No. 45 Droplight/Desnuda Tequila Honda of Rahal Letterman Lanigan Racing.

Series points leader Alex Palou also was near the bottom, 24th at 1:47.0512 in the No. 10 SOLO Cup Chip Ganassi Racing Honda.
