The Ford Mustang generations are commonly grouped as the original Mustang (1965–1973 model years), Mustang II (1974–1978), Fox-body (1979–1993), SN95/New Edge (1994–2004), S197 (2005–2014), S550 (2015–2023), and S650 (2024 onward). These labels are useful shorthand, not a complete specification guide: engines, trims, equipment, and body styles vary by model year and configuration.
To compare Mustangs or estimate what one is worth, start with its exact model year, body style, engine, transmission, trim, condition, and originality. For current new-car specifications, Ford’s 2026 U.S. lineup includes EcoBoost, GT, and Dark Horse models; packages and configurations affect equipment.
Ford Mustang generations at a glance
| Common generation name | Model years | What to know |
|---|---|---|
| Original Mustang / first generation | 1965–1973 | The 1965 range included coupe, convertible, and fastback body styles, six-cylinder and V8 engines, and optional performance equipment. Verify the exact model year and configuration. |
| Mustang II | 1974–1978 | A smaller era between the original Mustang and the Fox-body. Do not assume its specifications match those of other generations. |
| Fox-body | 1979–1993 | Introduced on Ford’s Fox platform; the era included the return of the 5.0-liter V8, the turbocharged SVO, and changing GT specifications. |
| SN95 / New Edge | 1994–2004 | A commonly used generation grouping. Engine and trim combinations require model-year-specific verification. |
| S197 | 2005–2014 | The 2005 redesign began this commonly recognized generation. Check year-level sources for engine outputs and special-edition equipment. |
| S550 | 2015–2023 | EcoBoost and GT were core offerings; the V6 was discontinued after 2017, according to Hagerty’s overview. |
| S650 | 2024 onward | The 2024 redesign began the seventh-generation era. Ford’s 2026 U.S. lineup includes EcoBoost, GT, and Dark Horse. |
Generation dates are practical model-year groupings. Historical timelines may describe milestones by calendar year, so check the model year and vehicle identification number when identifying a specific car.
Why the exact model year matters
A badge by itself does not establish a Mustang’s horsepower, equipment, or body style. Ford changed engines and specifications over time, and the same trim name can mean different things in different years. Confirm the year, engine, transmission, trim, and factory options before relying on a specification or comparing cars.

Examples from Mustang history
Hagerty’s account of the 1965 model year describes a broad range that included 170- and 200-cubic-inch six-cylinder engines, 260- and 289-cubic-inch V8s, and performance versions. That is a model-year snapshot, not a specification list for every first-generation car.
The Fox-body period shows why engine labels need context: Hagerty highlights the 5.0-liter V8’s return in 1982, the convertible’s return in 1983, and the turbocharged SVO’s arrival in 1984, followed by further changes to power and equipment.

How to compare Mustang generations and trims
Choose based on the specific car and your intended use, rather than assuming one generation or trim is universally best. For a useful comparison, line up cars with similar years and condition, then check:
- Model year and generation: Confirm the model year rather than relying only on a generation nickname.
- Body style and configuration: Compare like body styles and verify the actual factory equipment.
- Engine, transmission, and trim: Check the vehicle documentation and year-specific specifications; trim names alone are not enough.
- Condition and history: Review maintenance records, restoration quality, mileage, and any damage history.
- Originality and modifications: Record modifications and look for supporting documentation when originality matters.
- Comparable transactions: Use recent sales of similar cars, taking account of sale date, geography, and venue.
How much is a Ford Mustang worth?
There is no single meaningful value for “a Mustang.” Prices vary with model year, body style, engine, transmission, trim, condition, mileage, originality, documentation, geography, and sale date. A modified car and a documented original of the same year may not be comparable.

Date any market figure you publish and identify what kind of car it describes.

There is no single engine for each generation. Engine choices changed by model year, trim, and configuration. Identify the exact year and verify its engine using reliable year-specific records or specifications.
Which Mustang trim is right for me?
Start with your priorities—such as body style, engine, performance equipment, comfort, and budget—then compare the actual model-year configurations. Packages can change equipment, and the same trim name does not guarantee identical specifications across years.
