Forty-eight NASCAR Sprint Cup Series competitors took to the track at Las Vegas Motor Speedway on Thursday for a test session prior to Sunday’s Kobalt 400 at the track. The extra track time allowed teams an opportunity to adjust to a new intermediate rules package implemented by NASCAR for 2014. the Las Vegas race is the third race of the Sprint Cup season, but the first on an intermediate, or mile-and-a-half, track. The test also provided extra track time ahead of this weekend’s race.
Last week’s race winner at Phoenix International Raceway, Kevin Harvick was the fastest in the test session that was dominated by Chevrolet. Harvick’s fastest lap clocked in at 28.399 seconds or 190.148 mph. Chevrolets posted four of the five fastest lap times, with Ford driver Trevor Bayne being the only non-Chevrolet driver to work his way into the top-five of the speed chart during the session. Bayne posted a third-fastest lap time of 28.629 seconds, equal to an average lap speed of 188.620 mph.
Bayne wasn’t only the top Ford driver in the top-five, he was the only one in the top-10. The rest of the top-10 spots were claimed by either Chevrolet or Ford drivers. Series rookie Cole Whitt posted the fastest lap time among the Toyota camp with a time of 188.121 mph/28.705 seconds.
