At the Coke Zero 400, Newman had a strong racecar, evidenced by his leading four times for a race-high 25 laps. But for Newman, the race was once again an example of his bad luck streak at restrictor-plate races.

Despite leading five laps early, he finished 16 laps down in 38th. Newman suffered damage to his racecar on lap 81 when contact sent him spinning into the infield grass, ripping the splitter from beneath the front bumper.
