Its best-established engine milestones are the 383 V-8 and optional 426 Hemi at launch, the addition of a 440 rated at 390 hp for 1969, and the Hemi’s discontinuation after 1971. After 1975, the Road Runner name continued as a Volaré trim package, not as the same B-body model.
Values vary substantially by year, configuration, condition, originality, and sale date. Rather than relying on broad price ranges, compare similar cars and use current valuation tools and completed-sale evidence.
What are the Plymouth Road Runner generations?
| Generation | Model years | Overview |
|---|---|---|
| First | 1968–1970 | Original, relatively basic performance model based on the Belvedere. |
| Second | 1971–1974 | Redesigned with a more rounded body; the Hemi was discontinued after 1971. |
| Third | 1975 | One-year standalone B-body redesign with a plusher, more formal character. |
This is the common standalone-model breakdown used by CLASSIC.COM and described in Hagerty’s overview. The 1976–1980 Volaré-based Road Runner was a later trim-package use of the name, and should not be confused with these B-body generations.
First generation (1968–1970): the original performance-focused model
Plymouth introduced the Road Runner for 1968 as a relatively basic performance car based on the Belvedere. Its position emphasized performance over the more upscale equipment of pricier muscle-car models. Hagerty identifies the 383-cubic-inch V-8 as the base engine and the 426/425 hp Street Hemi as an available option.

For 1969, a 440 rated at 390 hp joined the engine lineup, and Plymouth added a convertible body style. These are key milestones, not a complete year-by-year specification list; specific equipment and ratings should be checked against year-specific factory literature.
Second generation (1971–1974): a rounded redesign
The Road Runner was redesigned for 1971 with a more rounded appearance. The muscle-car era was changing, and performance declined over this period. The 426 Hemi was discontinued after 1971. Because horsepower ratings and engine configurations changed, avoid comparing figures without identifying the model year, engine, and whether ratings are gross or net.
Third generation (1975): a one-year standalone model
The 1975 Road Runner was a one-year redesign with a plusher, more formal-looking B-body style, according to Hagerty. It is the final standalone B-body year commonly listed as a distinct generation. Detailed engine, transmission, and equipment claims require year-specific supporting sources.
What happened to the Road Runner after 1975?
From 1976, the Road Runner name continued as a trim package on the Plymouth Volaré. Hagerty describes this nameplate continuation as lasting through 1980. These cars belong in the broader story of the Road Runner name, but they are not additional B-body generations.

Engines, trims, and specifications: what is established?
The available research supports a few major engine and body-style milestones, but not a complete factory option table. Hagerty’s overview reports the following:
| Model-year context | Supported milestone |
|---|---|
| 1968 launch | 383-cubic-inch V-8 base engine; optional 426/425 hp Street Hemi. |
| 1969 | 440 rated at 390 hp added; convertible body style added. |
| After 1971 | The Hemi was discontinued. |
The original Road Runner’s market position favored performance with less upscale equipment than pricier muscle cars; Hagerty describes the 1975 redesign as plusher. Do not assume that a trim name, standard feature, or option remained consistent across years. Verify detailed specifications with factory literature or a specialist year-specific reference before relying on them.

What affects a Road Runner’s value?
There is no single dependable price range for every Road Runner. Hagerty offers year-based valuation tools, while CLASSIC.COM provides a market overview; both should be treated as research starting points rather than a substitute for comparing similar cars and recent transactions.
For a useful comparison, record:
- Year and body style: Compare cars from the same model year and generation where possible.
- Engine and transmission: Confirm claimed factory equipment with documentation rather than appearance alone.
- Condition and originality: Note restoration quality, modifications, and the car’s overall state.
- Documentation: Review VIN and fender-tag evidence where available; decoding references are research aids, not guarantees.
- Sale details: Distinguish asking prices from completed sales, and consider sale date and geography.
Do not apply an assumed premium for a particular engine, convertible body, originality, or condition without current comparable evidence. Values and market listings change over time.

Start by establishing exactly which car is being evaluated: a 1968–1975 standalone B-body Road Runner or a later Volaré trim-package car. Then compare the identification and documentation with year-specific references. A VIN or fender-tag decoding guide can help organize research, but an enthusiast reference is not an official guarantee of authenticity.
- Confirm the model year, body style, and whether the car is a standalone B-body model or a later Volaré-based trim package.
- Record the engine and transmission claimed by the seller, then seek supporting documentation and specialist verification.
- Assess condition, originality, restoration work, and modifications in person or through a qualified inspection.
- Compare recent completed sales of similar cars, noting their year, specification, condition, location, and sale date.
- Use a current valuation tool as one reference point, not as a guaranteed sale price.
