Verizon IndyCar Series championship leader Scott Dixon led a field of 25 drivers during the Thursday private test at Portland International Raceway. The Chip Ganassi Racing driver was fastest for a good portion of the late afternoon session, and traded top times with title rivals Will Power and Josef Newgarden from Team Penske.
Dixon’s No. 9 Honda (58.3593s) was only a fraction faster than Power’s No. 12 Chevy (+0.0335s) and Newgarden’s No. 1 Chevy (+0.1044s). Andretti-Herta Autosport’s Marco Andretti, who hovered near the leaders, finished fourth in his No. 98 Honda (0.2530s), teammate Zach Veach was fifth (0.3032s), and Dale Coyne Racing with Vasser-Sullivan’s Sebastien Bourdais was sixth (+0.3438s).
Andretti’s Alexander Rossi, who holds second-place in the championship standings, was ninth (0.3808s), and Carlos Munoz, making his first start after the Indy 500, was 19th in the Schmidt Peterson Motorsports entry normally driven by Robert Wickens (0.8029s). Despite the inactivity, Munoz wasn’t far off of SPM teammate James Hinchcliffe, who was 15th (+0.6220s).
A number of spins and crashes drew regular red flags. Juncos Racing’s Alfonso Celis Jr. and Rahal Letterman Lanigan Racing’s Graham Rahal were among those who required tows back to pit lane and did not return after their respective incidents.
