Power came from a 1.2 L (1,197 cc) Fiat OHV inline-four engine. Also, there were the 124 Special with a 1,438 cc OHV engine and the 124 Special T with 1,438 cc and 1,592 cc twin cam OHC engines. The twin cams are connected to a four-speed and five-speed gearbox. 1200 (1,197 cc) – 60 PS (44 kW; 59 hp) – 66 PS (49 kW; 65 hp) (1966–1974)
124 Sport Coupés were modern in chassis and engine design. Braking was via four 230 mm disc brakes with a front/rear weight-sensitive proportioning valve. It also had a sealed cooling system, viscous fan clutch and a toothed timing belt for the twin-cam engine, the first mass-produced engine to feature this instead of the usual chain-drive. [3]
The Fiat Twin Cam engine was designed by ex-Ferrari engineer Aurelio Lampredi. Bosch fuel injection replaced the previously used Weber carburetors midway through 1980. In 1981 and 1982, Fiat USA, Inc. partnered with Legend Industries to create around 700 turbo models for US markets.
In 1981 and 1983, the FSO Polonez Coupé, with three-door bodywork was introduced. It had the usual 1,481 cc engine with 60 kW (82 PS) or the 2.0-litre Fiat Twin Cam unit. It was the first FSO model to feature electronic ignition and fuel economizer owing to a supply of pre-heated air to the suction manifold. Only a few dozen were produced.
The Lampredi Twin Cam (Fiat Twin Cam) remains the most successful engine ever on the World Rally Championship circuit, garnering the most wins overall and 10 manufacturer championships for Fiat and Lancia.
