The Coronet and similar Plymouth Belvedere received complete redesigns in 1968, as did the Dodge Charger, which shared the B-body platform. There was a mild facelift in 1970. Trim levels initially included the base Coronet, Coronet Deluxe, Coronet 440, Coronet 500 and Coronet R/T. The Coronet Super Bee was introduced in early 1968 as a companion to the Plymouth Road Runner. In keeping with Dodge's position as a step above Plymouth, the Super Bee shared the Charger's Rallye instrument cluster and the Coronet 440's rear finish panel.
In mid-1969, the A12 package was introduced on the Super Bee. It included a 390 hp (291 kW) version of the 440 with three 2bbl Holley carburetors on an aluminum intake manifold, a black fiberglass lift-off hood secured with metal pins, heavy-duty suspension and 15" steel wheels with no hubcaps or wheel covers. The hood had an integrated forward-facing scoop which sealed to the air cleaner assembly and bore a decal on each side with the words "SIX PACK" in red letters, "Six Pack" being the name used for the 6-bbl induction setup when installed on a Dodge (Plymouth went with "440 6bbl" on the A12 Road Runners). The A12 Super Bee could be had with most Super Bee options, with the exception of air conditioning and tire-wheel packages. The A12 option was a 1969-only package, but the 440 6bbl returned in 1970 as an optional engine on both the Super Bee and the Coronet R/T. The Coronet R/T 2-door hardtop and convertible continued through 1970.
