[4] Designed by Jack Telnack, it featured an entirely new body which was larger and more roomy than that of its XY series predecessor, giving it the "coke-bottle" look.

[5] The addition of a two-door hardtop to the range marked the first time that this body style had been offered on an Australian Falcon since the XP series of 1965–1966.

The XA hardtop's longer doors with frameless windows were shared with the utility and van, with a different shape glass to suit the commercial vehicles' body apertures.

[4] While successful, the XA Falcon range proved to be short-lived as it gained a significant frontal appearance update to become the XB series in September 1973.

It also shared many options as used on the GT Falcon, such as the 12 slot steel wheels with plain brushed centre caps, the three spoke wooden rimmed steering wheel with rim squeeze horn and full GT dash instrumentation featuring tachometer, odometer, oil pressure, water temperature and voltmeter as standard.

[11][12] This significant road car was manufactured in Calypso Green metallic with a white vinyl interior, and has recently been completely restored.

Between April 1973 and August 1973, Ford Australia built 250 XA Falcon GTs fitted with the RPO 83 package, 130 of these being sedans and 120 being hardtops.

[13] RPO 83 comprised three variations from the standard XA Falcon GT, these being of a Holley 780 carburettor, 2.25 inch exhaust headers and a clutch slave cylinder hydraulic pipe heat shield.

[13] The 2.25 inch exhaust headers were subsequently homologated for the XA Falcon GT for Group C Touring Car racing, including the 1973 Hardie-Ferodo 1000.
