After being the first driver to take time in Saturday’s 55-minute morning practice session, Denny Hamlin topped the chart at 171.130 mph. The No. 11 car stayed atop the scoring pylon for the duration of the session.
On Friday, Hamlin won the pole for Sunday’s Ford EcoBoost 400. In this session, the No. 11 proved it has race speed, by being the quickest car by nearly one-tenth of a second. Dale Earnhardt Jr. was second on the board (170.681 mph).
Martin Truex Jr. was the first of the Championship 4 on one-lap speed at 170.020 mph, placing third on the chart. However, with roughly 25 minutes remaining in the practice, the No. 78 car slapped the outside wall, damaging the rear corner panel.
37 of 39 drivers took time in the practice. Kyle Busch and Austin Dillon ran 43 laps, the most of all drivers.
