Few Falcons spark debate quite like the AU. Launched in 1998 as the successor to the EL, it marked one of the biggest leaps in design and engineering Ford Australia had attempted in decades. The bold ‘New Edge’ styling split opinions from day one, but beneath the polarising panels was a tough, cleverly engineered Falcon that proved far more durable than its early reputation suggested.
Over time, the AU has shaken off the jokes and found its place as a cult favourite—valued for its strong drivetrains, bulletproof reliability, and bargain‑basement entry price. For many enthusiasts, it’s become the cheapest and most character‑filled gateway into Falcon ownership, and its once‑controversial looks now feel like part of its charm.
AU Falcon Overview
Production years: 1998–2002
Platform: All-new AU platform
Body styles:
- Sedan
- Wagon
- Ute
Major changes from EL Falcon:

AU Falcon Series Updates
The AU Falcon was released in three main updates:
AU Series I (1998–2000)
Initial release model.
AU Series II (2000–2001)
Styling revisions and quality improvements.
AU Series III (2001–2002)
Further refinement and reliability improvements.
Series II and III are generally considered the most desirable due to improvements.
AU Falcon Model Range
Ford offered a wide range of AU variants.
Main models included:
Falcon Forte – Base model
Falcon Futura – Mid-range
Falcon S – Sports variant
Falcon XR6 – Performance six cylinder
Falcon XR8 – V8 performance
Fairmont – Luxury model
Fairmont Ghia – Premium luxury
Performance variants included:
Tickford enhanced XR models
Utility and wagon variants were also widely used in commercial fleets.
AU Falcon Engines
The AU Falcon used updated versions of Ford’s long-running inline six and V8 engines.
Inline Six Engines
4.0L SOHC Inline Six:
Typical outputs:
- 157 kW (base)
- Up to 172 kW in XR6
VCT Engine
Later models introduced:
4.0L VCT Inline Six:
- Around 172 kW
- Improved torque delivery
- Better efficiency
AU Falcon V8
XR8 / Fairmont Ghia V8
5.0L Windsor V8:
- Around 185–200 kW depending on variant
The AU was among the last Falcons to use the Windsor V8 before the later Boss V8 engines arrived in BA.
AU Falcon Transmissions
Transmission options included:
4-speed automatic
Most common transmission.
5-speed manual
Available in some variants including XR models.
These transmissions are generally simple and durable if maintained.
AU Falcon Key Specifications
Typical AU Forte:
Engine: 4.0L inline six
Power: approx 157 kW
Torque: approx 357 Nm
Fuel economy: approx 11–13L/100km
Drivetrain: RWD
XR6:
Power: approx 164–172 kW
XR8:
Power: approx 185–200 kW
These figures were competitive for Australian large cars of the era.
AU Falcon Driving Experience
While often criticised for styling, the AU drove well compared to earlier Falcons.
Key characteristics:
- Comfortable suspension tuning
- Stable highway driving
- Predictable handling
- Strong low-end torque
- Good long-distance comfort
The AU remained popular with fleets partly because of these driving characteristics.
AU Falcon Reliability
Despite its reputation for styling controversy, the AU developed a strong reputation for mechanical durability.
Strengths include:
- Simple engine design
- Proven drivetrain components
- Relatively simple electronics
- Good parts availability
- Strong fleet durability history
Many AU Falcons have exceeded 400,000 km with proper maintenance.
This durability is a major reason they remain popular as cheap daily drivers.
Common AU Falcon Problems
Like any older vehicle, AU Falcons now mostly suffer age-related issues.
Cooling System Issues
Common ageing problems:
- Radiator deterioration
- Thermostat failures
- Hose wear
Preventative cooling system maintenance is recommended.
Intake Manifold Issues
Some engines developed intake manifold cracking issues over time.
Symptoms:
- Coolant loss
- Rough running
- Overheating risk
Upgraded replacements are available.
Suspension Wear
Common at higher km:
- Bush wear
- Ball joints
- Shock absorber wear
These are normal wear items.
Electrical Ageing
Possible issues:
- Central locking faults
- Window regulator failures
- Sensor ageing
Generally simple repairs.
Automatic Transmission Wear
4-speed autos may develop:
- Harsh shifting
- Delayed engagement
Servicing helps longevity.
AU Falcon Running Costs
AU Falcons remain among the cheapest large cars to own in Australia.
Ownership factors:
Purchase price: Very low
Parts cost: Low
Servicing: Affordable
Fuel economy: Moderate to high
Because of low purchase prices, they remain attractive to budget buyers.
Is the AU Falcon a Good Used Car Today?
AU Falcons can still make good budget cars depending on expectations.
Good choice if you want:
- Very cheap car
- Simple mechanical design
- Easy DIY maintenance
- Comfortable daily driver
- Strong engine durability
Less ideal if you want:
- Modern safety features
- Modern technology
- Low fuel consumption
- Premium interior quality
Condition is extremely important given age.
What To Check When Buying an AU Falcon
Important inspection areas:
- Cooling system condition
- Transmission operation
- Suspension wear
- Rust (in some cars)
- Service history
- Interior wear
- Electrical functions
A well maintained AU is far more important than trim level.
Which AU Falcon Models Are Best?
Popular choices include:
Best cheap daily:
AU Forte or Futura
Best budget sports Falcon:

Best V8 option:
AU XR8
Best overall picks:
Series II or Series III models
Later AU models are generally considered more refined.
AU Falcon Market Value Trends
AU Falcons remain among the cheapest Falcons.
General trends:
Base models:
Very affordable entry level
XR6:
Enthusiast interest increasing slightly
XR8:
