Josef Newgarden put Team Penske on the top of the charts in during IndyCar’s open test for the 107th Running of the Indianapolis 500.

The two-time NTT IndyCar Series champion used a draft to clock the 2.5-mile oval in 39.5281 seconds to put his No. 2 Shell Chevrolet in P1. Newgarden also flexed his muscle without a tow and paced the field with a 220.648 mph lap.

Conor Daly slotted in second with a late flyer of 39.5664s ahead of 2008 Indy champ Scott Dixon in third at 39.6846s. Long Beach winner Kyle Kirkwood carried the flag for Andretti Autosport in fourth place while two-time Indy winner Takuma Sato completed the top five.

The only incident of the session occurred when Rinus VeeKay and Callum Ilott collided on pit lane. VeeKay hit the outside pit wall and suffered minor damage to his No. 20 Ed Carpenter Racing Chevrolet. IndyCar assessed Ilott a five-minute time penalty for the incident.

Rain forced IndyCar to cancel Friday’s session, leaving teams with just Thursday to gauge themselves heading into the month of may.
