#14-Tony Stewart: Chassis No. 14-710: This car debuted in April in the Capital City 400 at Richmond (Va.) International Raceway, where it qualified 22nd and led four times for 118 laps before a late-race caution canceled Stewart's two-and-a-half second lead and forced him to settle for a third-place finish. It was then tested June 6-7 at Pocono (Pa.) Raceway and again during a Goodyear Tire Test June 12-13 at Bristol (Tenn.) Motor Speedway. The Lenox Industrial Tools 301 in July at New Hampshire Motor Speedway in Loudon marked Chassis No. 14-710's second career start. There, a new tire compound from Goodyear confounded Stewart and crew chief Steve Addington, and they labored to a 12th-place finish. The car returned to Richmond in September for its third career start via the Federated Auto Parts 400, where it rallied from its 28th-place starting spot to lead 15 laps before finishing fourth. Sunday's race at Martinsville (Va.) Speedway will mark the car's fourth career start.

#39-Ryan Newman: Chassis No. 39-691: This weekend, Newman will pilot Chassis No. 39-691, which has four starts and three top-10 finishes to its credit. Its most recent top-10 came last month at Richmond (Va.) International Raceway, where Newman led 13 laps and finished eighth. Prior to that, at Phoenix International Raceway in March, the chassis looked to be a lock for its third consecutive top-10 finish but, 56 laps shy of the checkered flag, Newman was sent spinning into the turn-four wall after contact with another car while racing side-by-side for fifth place. The incident relegated Newman to a 21st-place finish. Last season, the chassis competed at Richmond in September and Phoenix in November. At Richmond, Newman started 18th and fought his way into the top-10 near lap 100 and stayed in that relative position for the remainder of the 400-lap event, finishing eighth. Newman finished fifth at Phoenix in November.
