#4-Kevin Harvick: will pilot the No. 4 Budweiser/Jimmy John's Chevrolet SS built on Chassis No. 4-864 in the Martinsville 500 NASCAR Sprint Cup Series race Sunday at Martinsville (Va.) Speedway. Built in 2014, Chassis No. 4-864 made its debut at Martinsville last March, when it started 18th and led one lap and finished seventh. It made its second appearance at Martinsville in October, when it started 33rd and finished 33rd after being collected in an accident with Matt Kenseth.
#5-Kasey Kahne: Crew chief Keith Rodden has selected Hendrick Motorsports Chassis No. 5-925 for Sunday's race at Martinsville. This is a brand new car.
#10-Danica Patrick: will pilot Chassis No. 909 in the Martinsville 500. Previously a No. 41 team chassis, the car made its on-track debut with her Stewart-Haas Racing (SHR) teammate Kurt Busch last October at Martinsville (Va.) Speedway. He started 10th, led 21 laps and raced inside the top-10 until an oil line failure on lap 424 relegated him to a 36th-place finish.
#14-Tony Stewart: Chassis No. 14-742: This car first turned its wheels on a racetrack in 2012 during a test session Sept. 4-5 at the Milwaukee Mile in West Allis, Wisconsin, which prepared Chassis No. 14-742 for its debut in the Sept. 23 Sylvania 300 at New Hampshire Motor Speedway in Loudon. There, the car qualified third and led 38 laps before finishing seventh. Chassis No. 14-742 returned to another relatively flat, 1-mile oval when it made its second career start in the penultimate race of the 2012 season at Phoenix International Raceway. After qualifying ninth, a pit road miscue and a lap-282 spin conspired for a 19th-place finish. With a new 2013 Chevrolet SS body, Chassis No. 14-742 returned to Phoenix in February for its third career start, where it had a solid outing, qualifying sixth and finishing eighth. With the exception of a test June 25-26 at New Hampshire, the car sat idle for the remainder of the 2013 season. Chassis No. 14-742 reprised its testing regimen in 2014, with tests Jan. 30-31 at New Smyrna (Fla.) Speedway and Feb. 6 at Gresham Motorsports Park in Jefferson, Georgia. The March 2014 race at Martinsville (Va.) Speedway marked Chassis No. 14-742's first start in more than a year and its fourth overall. The run, however, was a quiet 17th-place effort. The car returned to Martinsville in October, where in just its second start of 2014, it qualified fourth and led 18 laps before finishing fourth. Chassis No. 14-742 returns to Martinsville this weekend for its first start this season and sixth overall.
#15-Clint Bowyer: Chassis No. 806 serves as Bowyer's primary chassis at Martinsville. Bowyer raced the chassis to top-10 finishes in both Martinsville races in 2014. He finished ninth in March and seventh in October. This weekend's back-up chassis also served as the back-up at both Martinsville races in 2014.
#24-Jeff Gordon: #24 crew chief Alan Gustafson has selected Hendrick Motorsports Chassis No. 24-902 for this Sunday's race. Gordon raced this chassis to a runner-up finish at Martinsville in October of last year.

Formerly a No. 10 chassis for Stewart-Haas Racing (SHR) teammate Danica Patrick, Chassis No. 865 debuted in March 2014 at Martinsville , where Patrick started 10th but struggled with an ill-handling racecar and finished 32nd. Its next event was in July at New Hampshire Motor Speedway in Loudon, where she started 29th and finished 22nd. Chassis No. 865 then raced again at Martinsville in October, where Patrick started 30th and finished 34th after being involved in a massive accident on the frontstretch late in the race. Chassis No. 865 will see its first laps of 2015 competition this weekend.
