Packard Balboa Concept

The 1953 Packard Balboa-X, as it was officially called, was a hardtop based on the Packard Caribbean convertible. The main point of interest on the car was the canopy-style C-pillar. Caribbeans never recieved a hardtop like the Balboa's, but they got a conventional one (covered with Hypalon) in 1956.

Drivetrain of the Balboa-X was stock Caribbean with a 327 c.i. Straight Eight that was distinguished from lesser Clippers Deluxe's engine by hydraulic valve train adjustment, and from the more expensive Patrician 327 by 5 instead of 9 main bearings.

Unique Attributes
The rear window had a reverse-slope and could be lowered for draft-free ventilation and a rear view without optical distortion. Further, the rear shelf was omitted for reasons of safety (loose articles in case of an accident), a modern attempt at the time. The Packard Predictor show car of 1956 also featured an opening, reverse angled rear window. Some years later, Mercury stuck on the idea and offered some models with a similar rear window treatment.
