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
In 1975, in a move to better compete with the AMC Gremlin, Ford introduced the 2.8L V6; while far less powerful than the Gremlin, the V6 gave the Pinto a feature unavailable in the Chevrolet Vega. Sales of the Mercury Bobcat were expanded to Lincoln-Mercury dealers in the United States; it was sold as a hatchback and wagon.
