|Kasey Kahne is using winning Pocono chassis from August|
#2-Brad Keselowski: Primary Chassis: PRS-861. Last Raced: Brand new chassis. Backup Chassis: PRS-838. Last Raced: Darlington (finished 32nd).
#5-Kasey Kahne: Crew chief Kenny Francis will unload Hendrick Motorsports Chassis No. 5-779 for Sunday night's event at Atlanta. Kahne has driven this car four times this season and averaged a 12.5 finish. He notably led 66 laps in this car and won at Pocono Raceway in August. He also led 114 laps in this chassis in March en route to a runner-up result at Las Vegas and later scored an 11th-place finish one month later at Texas Motor Speedway.
#9-Marcos Ambrose: The No. 9 team prepared chassis No. 847. Ambrose brought home a top-10 finish at Charlotte with this chassis earlier this season.
#10-Danica Patrick: Chassis No. 10-794: Chassis No. 10-794 was tested in the wind tunnel May 1 before being used by Patrick in the Coca-Cola 600 later that month at Charlotte (N.C.) Motor Speedway. Patrick started 24th and finished 29th after being involved in a multi-car accident on lap 320 of 400. After repairs, she managed to finish the race, but completed only 385 laps. The last time Patrick drove this car was in June at Kentucky Speedway in Sparta, where she started 29th and finished 23rd.
#14-Mark Martin: Chassis No. 14-736: This car debuted in 2012 in the Chase for the NASCAR Sprint Cup opener at Chicagoland Speedway in Joliet, Ill., where Tony Stewart qualified 29th and rallied to lead three laps before finishing sixth. Chassis No. 14-736 made its second career start in October at Charlotte (N.C.) Motor Speedway, and it had to rally again. After starting 32nd, a lap-16 run-in with Brad Keselowski necessitated numerous pit stops that dropped Stewart all the way to 36th in the 43-car field. But Stewart used Chassis No. 14-736 to claw his way back to a respectable 13th-place finish. The car made its third career start last November at Texas Motor Speedway in Fort Worth where it rallied yet again, overcoming its 21st-place starting spot to finish fifth. With a 2013 Chevrolet SS body honed in the wind tunnel, Chassis No. 14-736 visited Kansas Speedway in Kansas City in April for its fourth career start. It was a quiet outing, with Stewart qualifying 18th and finishing 21st. Its second start of 2013 came in June at Kentucky Speedway in Sparta. Finding the right handling package at the bumpy 1.5-mile oval proved elusive, as Chassis No. 14-736 qualified 25th and finished 20th. It gets a chance to redeem itself in its sixth career start this weekend at Atlanta Motor Speedway.
#15-Clint Bowyer: Primary chassis 777 finished 20th at Indianapolis. Backup chassis No. 724 has served as a backup several races in 2013, but not raced.

#39-Ryan Newman: Chassis No. 39-748: Newman will pilot Chassis No. 39-748 at Atlanta Motor Speedway in this weekend's Advocare 500. This chassis debuted at Texas Motor Speedway in Fort Worth last November, when Newman was able to overcome his starting position of 36th and a loose right-front wheel that dropped him from the top-10 to 25th with just 110 laps remaining to record a 12th-place finish. Since then, Chassis No. 39-748 was outfitted with a new front clip and a Chevrolet SS body, and saw its first laps of the 2013 NASCAR Sprint Cup Series season at Auto Club Speedway in Fontana, Calif. There, Newman overcame a late-race pit road speeding penalty to finish 10th. The No. 39 team turned the chassis around and brought it to Texas again in April, when Newman raced this Chevrolet SS to another 10th-place finish. Most recently, Chassis No. 39-748 raced in the Coca-Cola 600 at Charlotte (N.C.) Motor Speedway in May, when Newman finished sixth.
#43-Aric Almirola: The No. 43 team has prepared chassis No. 855 for Atlanta. Almirola drove the chassis to a 15th-place finish at Kentucky Speedway in June.
