Iowa IndyCar: Penske-Chevrolet goes 1-2-3 in practice
Team Penske-Chevrolet’s Josef Newgarden led his teammates Simon Pagenaud and Will Power in the only practice session prior to this afternoon’s qualifying runs for IndyCar's Iowa 300.
This year, IndyCars have their Borg-Warner twin turbos set at 1.5-bar boost – the same as on road and street courses – at the short ovals here in Iowa and also at Gateway next month.
There were two lengthy caution periods for track inspections in an otherwise incident-free hour.
Two-lap qualifying starts at 1.15pm local (Central) time with a further hour of practice starting at 6pm.
