5-time Sprint Cup champ Jimmie Johnson seeking to make history at the Coca-Cola 600

Jimmie Johnson is focused on chasing victory at the Coca-Cola 600. He says he's not thinking about his championship legacy.

A win Sunday night would be Johnson's fourth in NASCAR's longest race, trailing only Darrell Waltrip's five victories at Charlotte Motor Speedway. Johnson could also strengthen his series points lead with his third win this season as he chases his fifth Sprint Cup title. And a win would be a record seventh at Charlotte.

It's a resume already worthy of NASCAR's Hall of Fame, but it's not something the 37-year-old Johnson's ready to think about. Johnson said it's hard to consider his place in the sport when he's still competing.

Johnson won his record fourth All-Star race here last week.
