The Plymouth B-body series ultimately comprised four cars with nearly identical outward appearances (differing only in trim package, drive train and accessories).
The Superbird's unique styling was a result of homologation requirements for using the same aerodynamic nose and rear wing when racing the car in the NASCAR series of the time.
While the aerodynamic concept used to create the Superbird was identical to that of the 1969 Dodge Charger Daytona, they shared no common body components.
However, NASCAR effectively hobbled the low production winged cars after 1970 with strict regulations that limited the size of engines that could power them.
Cars using the rear-wheel-drive B platform include: Five different wheelbases were available: From 1988 to 1992, the B-body name was used again for the midsize front-wheel-drive Eagle Premier sedan, which was originally designed by and was slated to be built by American Motors with Renault until Chrysler's buyout of that company in March 1987.
