With this weekend’s NRA 500 at Texas Motor Speedway the first race for NASCAR’s new Generation 6 car under the lights, teams had two test sessions on Thursday to acclimate the car to the cooler temperatures at the 1.5-mile oval.
As he did in Las Vegas, Greg Biffle led the day’s testing. Biffle turned 14 laps in the second session and a fast lap of 192.864 mph. The Busch brothers were next, with Kurt also in the 192 range in the No. 78 Furniture Row Chevrolet at 192.369, and Kyle fastest in the 191 range in the No. 18 M&Ms Toyota for Joe Gibbs Racing (191.639).
This marked the first sessions for a handful of different drivers in new cars. Dillon, back in the No. 51 Phoenix Racing Chevrolet, clocked in seventh, with Brian Vickers 26th in Denny Hamlin’s usual No. 11 FedEx Toyota from JGR, and rookie Timmy Hill last of the 43 cars to take time in Frank Stoddard’s No. 32 FAS Lane Ford.
