Over the 21 years since NASCAR first visited Indianapolis Motor Speedway in 1994, Chevrolets have largely dominated proceedings at the venerable 2.5-mile track.
Friday evening's final practice ahead of Saturday qualifying for Sunday's Brickyard 400 was no break from tradition.
Chevrolet drivers made it a clean sweep of the top five speeds in the 1-hour, 55-minute "Happy Hour" as Kurt Busch's Stewart-Haas Racing Chevy topped the leaderboard with a lap of 181.987 mph. Fellow Chevy drivers Kevin Harvick, Kyle Larson, Jimmie Johnson and Martin Truex Jr. completed the top five.

The highest non-Chevy driver was sixth-place Kyle Busch, in a Toyota. Carl Edwards, Kasey Kahne, Austin Dillon and Tony Stewart rounded out the top 10, respectively.
Final practice was stopped momentarily when Timmy Hill spun off Turn 4 and hit the wall with his No. 98 Ford early in the session.
This was the third practice in which drivers made laps with the new, high-drag aero package being used on Sprint Cup Series cars this weekend and at Michigan International Speedway next month.
The new aero package is highlighted by a nine-inch rear spoiler with a one-inch wicker bill, a two-inch front splitter and a 43-inch radiator pan. The package was expected slow the cars down by about 10 miles per hour, but the disparity hasn't been as significant as anticipated.
