The Ford Falcon (XC) is a full-size car that was produced by Ford Australia from 1976 to 1979. It was the third and last iteration of the third generation of the Falcon and also included the Ford Fairmont (XC)—the luxury-oriented version of the Falcon.
Overview
The XC series was a facelift of the XB Falcon, itself an upgrade of the XA Falcon which had entered production in 1972.
Introduced in July 1976, the XC included significant changes to comply with new Australian Design Rules. ADR27A set limits for the emissions of hydrocarbons, carbon monoxide, and oxides of nitrogen.[1] To meet the new requirements, engine compression ratios were dropped, and the engines now featured an exhaust gas recirculation valve and positive crankcase ventilation. In order to offset power losses as a result of implementing emissions controls, Ford upgraded the six-cylinder engines with a new crossflow cylinder head with larger valves, and fitted all V8 engines with four-barrel carburettors. While quoted power outputs were lower than those claimed for the XB Falcon, this reflected a move from SAE gross to DIN methodology, which measured power of the engine as installed in the car with cooling, charging and exhaust systems installed.
