Plastic automotive engine
Version one was based on Ford's 2.3-liter Pinto engine and weighed (vs. for its cast iron counterpart). It was designed to produce at 9200 rpm. It was composed of metal cylinder sleeves, metal combustion chamber tops, metal piston crowns, bearings, valves and seats, and a stock 2.3L Pinto crankshaft. Nearly everything else in the engine, including the block, rods and piston skirts, were made of glass reinforced Polyamide-imide thermoplastic resins manufactured at the time by Amoco Chemicals Co. The engine was never installed in a vehicle.
Ford Pinto
The Ford Pinto went on sale on September 11, 1970 in one bodystyle, a fastback sedan with an enclosed trunk. A hatchback became available on February 20, 1971, debuting at the Chicago Auto Show. In 1971, the Pinto brochure came with a paper cutout Pinto that one could fold to make a 3D model. Marketed as the "Runabout," the hatchback went on sale five days later, priced at $2,062. The hatch itself featured exposed chrome hinges for the liftgate and five decorative chrome strips, pneumatic struts to assist in opening the hatch, a rear window approximately as large as the sedan's, and a fold down seat — a feature which became simultaneously an option on the sedan. The hatchback model matched the sedan in all other dimensions and offered of cargo space with its seat folded. By 1972, Ford redesigned the hatch itself, with the glass portion of the hatch enlarged to almost the entire size of the hatch itself, ultimately to be supplemented for 1977–1980 with an optional rear hatch that was entirely glass.
