The 1955 Mercury D-528 was a car developed by Ford Engineering to test various ideas that were new and even wild at the time. It was built to test advanced concepts in seating, lighting, air conditioning and front frame design.
Instead of standard tail fins of the era, the D528 had hinged compartments on either side of the trunk. One conceals the gas tank, the other the spare tire.
Ford’s first reverse-sloping retractable rear window, a feature that would show up on a couple of the corporation's models such as the 1957 Mercury Turnpike Cruiser and the 1958 Lincoln. The 1955 Mercury D-528 was never destroyed. It is on display at the Petersen Auto Museum in California.
This is my Tribute to the 1955 Mercury D-528. Enjoy, Mario
