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
After structural design on alternate body styles encountered obstacles, Ford offered the Pinto solely as a two-door sedan, with entry level models priced at $1850, undercutting GM's Chevrolet Vega and directly targeting imported models — which included such new competitors as the Mazda 1200 in 1971, the Subaru DL in 1972, and the Honda Civic in 1973.
