A new high-performance package was added, the R/T (Road/Track, with no 'and' between the two, as in the then highly influential, muscle car promoting Road & Track magazine). The R/T came standard with the previous year's 440 Magnum, with the 426 Hemi optional.

In 1968, Chrysler Corporation began an ad campaign featuring a cartoon bee with an engine on its back promoting models called the Scat Pack. The Coronet R/T, Super Bee, Dart GTS, and Charger R/T received bumble-bee stripes (of two thin stripes framing two thick ones). The stripes were standard on the R/Ts and came in red, white, or black, but could be deleted at no extra cost.

The 1968 film Bullitt helped popularize the Charger R/T for its notable car chase sequence alongside the titular character's 1968 Ford Mustang GT through the streets of San Francisco, which has been regarded as one of the most influential car chase scenes in movie history. In the film, a black Dodge Charger R/T 440 is chased by Steve McQueen's Ford Mustang GT, jumping on the San Francisco slopes. The 1968 model year Charger sales increased to 96,100, including over 17,000 Charger R/Ts.
