#39- Ryan Newman - Chassis No. 39-645: With one start already this season, Chassis No. 39-645 is no stranger to victory lane. In its first start in 2012, Newman drove this chassis to the winner’s circle at Martinsville Speedway. Newman won despite falling one lap down early in the race after receiving a penalty for speeding on pit road. And, once he got back on the lead lap, Newman took advantage of every spot in front of him. He took his first – and only– lead of the day on lap 504 of 515, when he dove under the leaders after they collided in turn one. He held off another driver on the final restart in a tough duel before pulling away on the last lap to win. The chassis also earned a 10th-place finish at New Hampshire Motor
Speedway in Loudon in July. The chassis made four starts last year – two at Martinsville and two at New Hampshire.
