Ryan Newman drove this #31 Caterpillar Darlington Throwback Retro paint scheme for Richard Childress Racing in the Bojangles' Southern 500 NASCAR Monster Energy Cup Series race at Darlington Raceway on Sunday September 2, 2018. This paint scheme pays tribute to the car that Neil Bonnett drove for RCR in 1993 when he returned from his crash at Darlington in 1990.
