The 2008 Indy winner lapped the iconic 2.5-mile Indianapolis Motor Speedway at 224.047mph, some 0.85mph faster than Team Penske-Chevrolet’s two-time and reigning champion Josef Newgarden.
A.J. Foyt Racing-Chevrolet’s Tony Kanaan was the first driver to click past 220mph as the 2013 Indy winner drafted past Marcus Ericsson’s Chip Ganassi Racing-Honda 17 minutes into the two-hour session. He was soon edged by Dixon and 2016 winner Alexander Rossi, before another Foyt car went fastest, that of Charlie Kimball.
The 2018 winner Will Power sent Team Penske into the 221mph zone, and Dixon then towed up behind Colton Herta to click off a 222.
Marco Andretti came to a halt on pitlane entry with an electrical issue, bringing out the first caution of the day, not long after Marco’s temporary Andretti Autosport teammate James Hinchcliffe put his Genesys car at the top of the speed charts with a 223.071mph lap.
This held firm as fastest speed until the final 10 minutes when Josef Newgarden picked up a strong draft from a couple of cars to hit an average of 223.188mph around the iconic 2.5-mile Speedway. This was then thoroughly eclipsed by Dixon’s 224.047.
Behind this pair, Hinchcliffe retained third as fastest Andretti car ahead of Kanaan and Ryan Hunter-Reay who turned fastest no-tow speed at 219.7.
2017 winner Takuma Sato was seventh for Rahal Letterman Lanigan-Honda, while Zach Veach split two of the Ed Carpenter Racing machines.
Next up was two hours for Rookies and Refreshers.
