Additionally, Stewart's team decided to change the engine in the backup car before his qualifying run.
Stewart will start 29th on Saturday night. Because he changed engines before qualifying, Stewart will not have to start from the back of the field.
TMS GOES GREEN
For the second straight year, NASCAR is using environmentally friendly fuel in all three of its top racing series, including Saturday's Samsung Mobile 500.
The fuel used in the Sprint Cup cars is Sunoco Green E-15, a 15 percent ethanol-blended fuel as NASCAR continues to be on the leading edge of green technology, particularly with the use of American Ethanol.
TRUCKS RUNNING AT ‘THE ROCK'
The Camping World Trucks Series will make its appearances at TMS in June and November, but this week, the series is running at Rockingham Raceway in Rockingham, N.C., on Sunday.
Known simply as “The Rock,” the famous track has been absent from any NASCAR schedule for eight years when the sport's powers looked for tracks in bigger markets — like Texas Motor Speedway.
The Sprint Cup used to make two yearly trips to Rockingham, but those dates were given to Fontana, Calif., and Texas after the 2004 season.
