CHARLOTTE, N.C. — There will not be an eighth NASCAR title for Jimmie Johnson and Chad Knaus.

Hendrick Motorsports will split the driver and crew chief — the longest pairing in NASCAR — at the end of a disappointing season. Johnson has not won a race in 17 months and was knocked out of the playoffs in the first round. Johnson and Knaus won their record-tying seventh championship in 2016 but have slumped in the two years since.
