In what was a test session for the full XFINITY Series field Friday at Indianapolis Motor Speedway, Elliott Sadler posted the top time in the opening practice of the weekend.
Circling the famed 2.5-mile oval in 54.080 seconds (166.420 mph), he led JR Motorsports teammate Justin Allgaier by 0.068 seconds.
The true highlight of the day was the difference in speeds from last year. With the XFINITY Series debuting an aero package, which includes an aero duct cover, a restrictor plate, a bigger spoiler and larger front splitter, Sadler’s speed was more than 25 mph behind the 2016 pole speed.
The changes were also seen visually, as the session ended with a pack of nearly 10 cars drafting in a line, with multiple passes made in this time.
Kyle Busch, who hasn’t lost an XFINITY or Cup race at Indy since 2014, finished third fastest with Joe Gibbs Racing teammate Erik Jones in fourth. Paul Menard was fifth with William Byron, Tyler Reddick, Brennan Poole, Cole Custer and Matt Tifft the top 10.
