The 1981 model year
Overview
For 1981, Ford offered Thunderbird, Town Landau, and the new top-line Heritage. The regular Thunderbird and Town Landau standardized a 3.3-liter inline-six with SelectShift and offered the 4.2-liter V8; Heritage standardized the 4.2. Automatic Overdrive was available with the 4.2 and required with the optional 5.0-liter V8.
Specifications
- Engines
- 3.3-liter inline-six (Thunderbird and Town Landau standard)
- 4.2-liter V8 (optional; Heritage standard)
- 5.0-liter V8 (optional with Automatic Overdrive)
- Transmissions
- SelectShift automatic, Automatic Overdrive
- Body styles
- Two-Door Coupe
Year over year
What changed
- Heritage became the new top-line Thunderbird model.
- The 3.3-liter six became standard on Thunderbird and Town Landau, while Heritage retained a standard V8.
- The 4.2-liter V8 could now be paired with Ford's Automatic Overdrive.
Worth knowing
Notable
- Carriage Roof, Exterior Decor, and Interior Luxury are option groups rather than separate model lines.
- Heritage is the only model in the brochure with the 4.2-liter V8 explicitly standard.
Living with it
Reliability & ownership notes
- Use the engine-specific oil interval: 10,000 miles for the six and 7,500 miles for V8s.
- Replace spark plugs and the engine air filter at 30,000 miles, and coolant at 50,000 miles or three years.
- Confirm engine and transmission before ordering parts; the 5.0-liter V8 required Automatic Overdrive.
