The Generation 6 NASCAR Sprint Cup cars have been fast at every track since being introduced at Daytona International Speedway last February at the Daytona 500.
At Friday’s first practice for Sunday’s Crown Royal presents the Samuel Deeds 400 at the Brickyard, speeds were up again from marks set last season in the old Gen 5 cars.
Denny Hamlin won the pole in 2012 in the No. 11 Joe Gibbs Racing Toyota with a lap of 182.763 m.p.h.
Juan Pablo Montoya was the fastest driver on the day at 185.410 m.p.h. in the No. 42 Earnhardt Ganassi Racing Chevrolet as he led a parade of Chevys on the speed chart.
In all, the top six drivers on Friday were faster that Hamlin’s mark.
That is still significantly slower than the track record for NASCAR — 186.293 m.p.h. set by Casey Mears in 2002 — on the 2.5 mile Indianapolis Motor Speedway.
