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.
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 was the first model to comply with the new pollution regulations specified under Australian Design Rule 27A. The response to the 1 July 1976, mandatory anti-pollution laws (ADR 27A), was to redevelop the Falcon six cylinder engines with a cross-flow head for greater efficiency.
Visually, the XC Falcon was given a restyle treatment. The XC had a less aggressive nose which incorporated two round headlights on Falcon models and two rectangular headlights on Fairmont models. Ford also addressed the vision problems of the XA and XB by utilizing the rear doors from the contemporary model FAIRLANE which had the effect of removing the coke bottle look., along with installing an all-new dash and installing higher front seats. The preceding XA and XB series were the last model Falcons to use coke bottle styling. It was succeeded in 1979 by the XD Falcon which utilised similar styling to Ford's European Granada models.
The XC Falcon range of passenger vehicles consisted of nine models:
- Falcon Sedan
- Falcon Wagon
- Falcon 500 Sedan
- Falcon 500 Wagon
- Falcon GS Hardtop
- Fairmont Sedan
- Fairmont Wagon
- Fairmont Hardtop
- Fairmont GXL Sedan
The Fairmont models were not badged or marketed as Falcons.
The XC Falcon range of commercial vehicles consisted of five models:
- Falcon Van
- Falcon 500 Van
- Falcon Utility
- Falcon 500 Utility
- Falcon Sundowner Van
Unique to the XC model was the GXL version of the Fairmont, Available in 4.1L Straight 6, or 4.9L Cleveland V8. An upgraded engine package, the GT Power Pack, used the larger 5.8L Cleveland v8. The Fairmont GXL was replaced in the following XD range with the Fairmont Ghia model.
GS Rally Pack
A GS Rally Pack was fitted as standard equipment on the Falcon GS Hardtop  and was available as an option on Falcon 500 Sedan and Wagon, Fairmont Sedan and Wagon, Falcon Utility and Van  and on Falcon 500 Utility and Van. The pack included special paint treatment, bonnet scoops, bumper overriders, slotted steel wheels, enhanced instrumentation, a sports steering wheel and long range driving lights. The driving lights were not included when the pack was fitted to Fairmont models.
Limited edition models
Ford Falcon Cobra
In August 1978 Ford Australia introduced the limited production Falcon Cobra, a high-performance version of the XC Falcon Hardtop. Only 400 were built, including 4.9-litre and 5.8-litre street versions and 30 "Bathurst Specials".
Allan Moffat Special
In 1977 a limited number (500) of the Falcon 500 sedan were marketed as Allan Moffat Specials. These cars received XB GT-style blackouts and a sticker on the front doors consisting of Allan Moffat's signature and an Australian flag, as well as other options such as the GS Rally pack and Sports handling suspension as standard. 
The Falcon Sundowner Van, based on the Falcon 500 Van, was introduced in 1977. It included options from the Falcon GS Hardtop, such as comprehensive instrumentation, bonnet scoops, slotted sports road wheels and driving lights, with side protection moulding's and rear side glass deleted. Side and rear decals were included in the package.
The GS 500 Hardtop formed the basis for the Ford Falcon Cobra and a customer racing program, with a special "Evolution" (and later Evo II) package to homologate parts. At the 1977 Hardie-Ferodo 1000, Allan Moffat and Colin Bond drove Group C specification Hardtops to a "1, 2" formation finish. Moffat later went on to win the 1977 Australian Touring Car Championship driving both an XB Falcon GT Hardtop and XC Falcon GS 500 Hardtop.
