FONTANA, Calif. – Graham Rahal held onto the lead out of a caution with three laps left to earn his second IndyCar win, closing out a wild, record-setting day at Auto Club Speedway on Saturday.
A sparse crowd showed up to Auto Club Speedway, but the few fans got to see quite a show as cars sling-shotted past each other at an average of 205 mph and raced up to five-wide around the 2-mile oval.
The 500-mile race eclipsed the season high for lap changes — 37 at Indianapolis — by the midpoint and had 83 overall, topping the IndyCar record of 73 set at Auto Club Speedway in 2001.
Rahal went in front late and stayed there after a late red flag, winning under caution after Ryan Briscoe went airborne in a collision with Ryan Hunter-Reay. Rahal's first victory was at St. Petersburg in 2008.
