The Final Evolution of the Classic Muscle Falcon
By 1976, the Falcon had already cemented its place as Australia’s go‑to family cruiser and weekend warrior. The XB had sharpened the XA’s foundations with tougher styling, better road manners, and the legendary GT‑HO Phase V development program — but Ford Australia was gearing up for the next evolution.
That step was the XC. As the final chapter of the original ‘coke‑bottle’ Falcon shape, it brought subtle but meaningful updates: cleaner lines, improved safety engineering, and a raft of refinements that made the big Ford feel more modern without losing its muscle‑car edge.
Where the XB refined the formula, the XC polished it. Better ergonomics, improved handling, and more contemporary features all arrived without diluting the Falcon’s unmistakable performance DNA. It was the last of its silhouette — and one of the most complete Falcons of the era
Design and Styling Comparison
Exterior Design
XB Falcon styling included:
- Aggressive “coke bottle” shape

XC Falcon updates included:
- New grille design with wider horizontal bars
- Revised bumper styling for a slightly more modern look
- Subtle tail light redesign
- Minor side trim updates
- Continuation of bonnet bulges and flared guards on GT-HO models
The XC maintained the muscular “coke bottle” proportions but looked slightly more contemporary and refined than the XB, signalling Ford’s attention to detail in the final iteration of this body style.

The XC felt like a more polished, refined interior without losing the Falcon’s driver-focused character.
Platform and Engineering Changes
The XC retained the XB’s platform but included meaningful refinements.
Chassis and suspension:
- Further tuned suspension for improved comfort and handling
- Minor geometry adjustments for better cornering stability
- Strengthened suspension components for high-performance models
Brakes and safety:
- Optional front disc brakes across more variants
- Improved pedal feel and braking response
- Reinforced body structure for improved occupant safety
Performance engineering:
- GT-HO Phase VI variants received minor driveline tuning improvements
- Better cooling for high-output 351 V8s
- Peak refinement of “coke bottle” Falcon suspension and handling
The XC represented the most refined and safest iteration of this generation of Falcon.
Engine and Drivetrain Comparison
