#14-Tony Stewart: Chassis No. 14-827: This car debuted in July 2014 during the Brickyard 400 at Indianapolis Motor Speedway. Stewart used it to qualify sixth, but in the race the car was persistently loose and it finished 17th. It was a reversal of fortune for the car, for in its lone test prior to Indianapolis it excelled, as Kevin Harvick drove it to the fastest speed of anyone participating in the Dec. 9, 2013 test session at Charlotte (N.C.)Motor Speedway. Chassis No. 14-827 next raced at Chicagoland Speedway in Joliet, Illinois, where it had a quiet weekend, qualifying 22nd and finishing 18th. The car returned to Charlotte in October where it made its third career start, qualifying a strong fourth but finishing 21st, bedeviled by a tight-handling condition. Its last start of 2014 came in November at Texas Motor Speedway in Fort Worth, where in qualifying it set the fastest lap in a stock car at a 1.5-mile oval when Stewart drove it to a lap of 26.985 seconds at 200.111 mph. It was the first time a stock car surpassed the 200 mph mark on a 1.5-mile oval. The car performed admirably in the race, finishing 11th. The car sat idle until April 2015 when it appeared at Bristol (Tenn.) Motor Speedway. It was a solid effort with the sixth-place finish at the concrete oval being the car's best among its five career starts. Chassis No. 14-827 returns to the concrete with this weekend's race at Dover.

International Speedway.
#47-A.J. Allmendinger: Chassis 499: "We're bringing the same car AJ raced at Phoenix International Raceway and Kansas Speedway," crew chief Brian Burns said. "So, it's fairly new and only its third race. We debuted it at Phoenix and lost a motor in practice. AJ drove from the back of field and overcame bad track position to finish 17th. We also had our jack man Mike Klein go out with an injury mid-race and he's our pit coach as well. I feel pretty good about this car. We're hoping for a solid weekend."
