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
For 1975, the Bobcat was added to the U.S. market and sold initially in upgraded levels of trim as the Runabout hatchback and Villager wagon. Lesser trimmed versions were offered in subsequent model years. The Bobcat was never offered as a 2-door sedan with an enclosed trunk for the U.S. market. All Bobcats were restyled with a domed hood and a taller vertical bar grille styled to look like senior Mercury models. Throughout all the model years Bobcats were given various appearance options similar to the Pinto's.
