Chip Ganassi Racing’s Chevrolets took the top two spots in Friday’s NASCAR Cup practice session at Dover International Speedway.
Kurt Busch was the fastest of the 37 drivers that took to the one-mile concrete oval with a speed of 168.445 mph, which is four mph faster than the track qualifying record of 164.444 mph, set in June 2014 by Brad Keselowski.
A total of 23 drivers eclipsed Keselowski’s track record during Friday’s practice.
Busch’s CGR teammate Kyle Larson was second-fastest at 168.106 mph. Larson and Busch were the only drivers over 168 mph.
The fastest Toyota driver was Denny Hamlin, who was seventh-fastest at 167.496 mph.
This was the only practice session today. Cup qualifying for Sunday’s Gander RV 400 takes place this afternoon at 3:35 p.m. ET.
