INDIANAPOLIS — If there's one thing every driver at the Indianapolis Motor Speedway knows, it's that Indiana weather can change faster than a pit stop. Day 2 of Indy 500 practice proved exactly that, with temperatures dropping noticeably from Tuesday's warm session. But for the 33 drivers competing in this year's race, every condition is a learning opportunity.
Marcus Ericsson, winner of the 106th running of the Indianapolis 500 in 2022, knows this track better than most. Now competing in his eighth Indy 500, the Swedish-born driver for Andretti Global took a moment after Wednesday's six-hour practice to break down how the shifting conditions are shaping his team's approach.
"Yesterday it was very warm, very nice conditions," Ericsson said. "Today with the wind and the cooler temps, it really changes the behavior of the car. I think it was good for probably all teams to sort of see how the car changes in those conditions. And I think, for us, we learned some good stuff from it."
That adaptability is key—especially when you've called Indiana home since late 2018. Ericsson knows better than to make assumptions about race day weather. "Looking at qualifying, the same place is going to be warmer for Saturday and Sunday. But, obviously in Indiana, you never know until we wake up in the morning."
On the track, Ericsson showed steady improvement. After logging just 45 laps on Tuesday, he turned 83 laps in Wednesday's practice and boosted his top speed by nearly two mph, hitting 224.274 mph—good for 19th overall. Even more impressive? He ranked third in no-tow speed, thanks to a standout 17th lap that clocked in at 221.204 mph.
As the field gears up for qualifying, here's a look at Wednesday's top performers:
#1. Conor Daly, Chevrolet, Dreyer & Reinbold Racing — 228.080 mph (86 laps)
#2. Alex Palou, Honda, Chip Ganassi Racing — 228.026 mph (118 laps)
#3. David Malukas, Chevrolet, Team Penske — 227.139 mph (56 laps)
#4. Graham Rahal, Honda, Rahal Letterman Lanigan — 226.835 mph (58 laps)
#5. Romain Grosjean, Honda, Dale Coyne Racing — 226.591 mph (77 laps)
#6. Scott Dixon, Honda, Chip Ganassi Racing — 226.xxx mph
With qualifying weekend on the horizon and the unpredictable Indiana forecast keeping everyone on their toes, one thing is certain: the drivers who can adapt fastest will have the edge when it matters most.
