#5-Kasey Kahne: Crew chief Kenny Francis will unload Hendrick Motorsports Chassis No. 5-809 for Sunday's event at Chicagoland. Kahne drove this car to a third-place finish at Indianapolis Motor Speedway in July. Most recently, he finished seventh while driving this car at Michigan International Speedway in August.
#9-Marcos Ambrose: The No. 9 team will bring new chassis No. 842 this weekend to Chicago. The team last ran this chassis at Pocono Raceway where they started in eighth and finished in the 12th spot.
#10-Danica Patrick: Chassis No. 10-805: Chassis No. 10-805 was used for the first time in July at the Indianapolis Motor Speedway where Patrick started 33rd and finished 30th.
#14-Mark Martin: Chassis No. 14-707: This car made its first start in May 2012 in the non-points NASCAR Sprint All-Star Race at Charlotte (N.C.) Motor Speedway. It was an unassuming debut, as Chassis No. 14-707 started ninth and finished a quiet 17th. The car sat idle until late August where it was used for the Labor Day weekend event at Atlanta Motor Speedway. It started strong by qualifying on the pole and took the lead from Greg Biffle on lap two and continued to pace the 43-car field for eight laps. But as the race wore on, Chassis No. 14-707 struggled with its handling, leaving it one lap down in 22nd when the race ended. With 2013 Chevrolet SS bodywork covering it, Chassis No. 14-707 was tested March 7 at Las Vegas Motor Speedway and April 11 at Texas Motor Speedway in Fort Worth. The Brickyard 400 at Indianapolis Motor Speedway marked the car's first start of 2013, and it was a solid one, with Chassis No. 14-707 qualifying fifth and finishing fourth. The car returns to action this weekend at Chicagoland Speedway in Joliet, Ill., where on Sunday it will make its third points-paying start and its fourth overall.

#39-Ryan Newman: Chassis No. 39-733: A workhorse of the No. 39 fleet, Chassis No. 39-733 debuted at Indianapolis Motor Speedway in July 2012, when Newman recorded a seventh-place finish. The crew turned the car around in just a couple of days and took it to Pocono (Pa.) Raceway, where it finished sixth. Two weeks later, the chassis was back on track at Michigan International Speedway in Brooklyn, where it finished eighth. The chassis earned its first top-five finish at Chicagoland Speedway in Joliet, Ill. The chassis next raced three weeks later at Dover (Del.) International Speedway. The chassis made its last start of 2012 at Kansas Speedway in Kansas City in October, when Newman was involved in an incident that forced him to retire from the event prematurely. Chassis No. 39-733 was outfitted with a new front clip and a Chevrolet SS body over the offseason, and saw its first laps of 2013 at Kansas in April, when Newman finished 14th. He then raced this Chevrolet SS to a 10th-place finish at Darlington (S.C.) Raceway in May. Newman again raced Chassis 39-733 at Pocono in June, where he recorded a fifth-place finish. Newman was in contention to score another top-10 finish with Chassis 39-733 at Kentucky Speedway in Sparta in June, but a late-race restart saw him shuffled to 14th when the checkered flag waved. Then, Newman qualified the car on the pole and led 45 laps en-route to earning his first win of the 2013 season in July's Brickyard 400 at Indianapolis. A week later, Newman overcame a series of slow stops on pit road at Pocono to record a fourth-place finish. Most recently, Newman fought through an ill-handling condition to finish 13th at Michigan.
#43-Aric Almirola:: The #43 team has prepared chassis No. 864 for Chicagoland. This is a new chassis that the team tested in Chicago in August.
#48-Jimmie Johnson: will drive chassis No. 799 at Chicago. Chassis No. 784 serves as the backup.
