Johnson, Friday's pole winner, needs only to finish at least 25th to win an unprecedented fourth straight points title.
"I'm glad that we have this late-season push each year, especially with the (Race for the Chase, the season-ending battle for the points title) in play," Johnson said this week on his Web site.
Also, Matt Kenseth drives for DeWalt Power Tools for the last time; Jamie McMurray does the same for Roush Fenway Racing; 50-year-old Mark Martin becomes the oldest driver to finish in the Top 10; Michael Waltrip ends his last full-time season; and Rick Hendrick, for whom Johnson drives, will join Petty Enterprises with his ninth ownership championship when Johnson starts the race at the Homestead-Miami Speedway.
