When did Ford switch from F-100 to F-150?
Ford switched from the F-100 to the F-150 for the 1975 model year, introducing the F-150 as the half-ton light-duty pickup and replacing the F-100 in its U.S. lineup.
To understand this change in context, it's helpful to review the broader history of Ford's F-Series and why the brand settled on the F-150 branding in the mid-1970s. For decades, Ford built a wide range of pickups under the F-Series name, with different badges signaling payload and duty. The shift in the mid-1970s aligned marketing with a payload-based naming convention that persists in various forms to this day.
Historical context of the F-Series
The F-Series line debuted in 1948 as Ford’s postwar solution for a growing market of light-, medium-, and heavy-duty pickups. Over the years, Ford’s badges evolved from a broad F-1 to F-8 range toward more standardized names for differing payloads. By the 1960s and early 1970s, Ford had begun using light-duty F-100, mid-range F-250, and heavy-duty F-350 designations as the core lineup for customers seeking different capabilities.
Key milestones that shaped the evolution of the F-Series include:
- 1948: Ford launches the F-Series family of pickups.
- 1953–1969: The range solidifies into light-, medium-, and heavy-duty variants, with badges like F-100 (light), F-250 (mid), and F-350 (heavy) appearing in various generations.
- 1975 model year: The F-150 debuts, effectively replacing the F-100 in the light-duty lineup; the heavier variants continue as F-250 and F-350.
The transition to the F-150 branding became a lasting hallmark of Ford’s half-ton trucks and helped standardize marketing across the entire F-Series family.
The switch to F-150: details
The 1975 launch marked more than a name change; it reflected a broader branding shift toward payload-based nomenclature that would guide Ford’s marketing for decades. The F-150 name signaled a half-ton capacity and created a more intuitive lineup for buyers, dealers, and promotional materials alike.
Why Ford chose the F-150 branding
The move to F-150 was driven by a desire to clearly communicate payload capacity and to align the half-ton truck with a simple, scalable naming scheme that could extend across the range (150 for half-ton, 250 for three-quarter-ton, 350 for one-ton).
Milestones in the transition:
- 1975 model year: Ford introduces the F-150 as the light-duty successor to the F-100; marketing and dealer catalogs begin using F-150 across the full line (F-150, F-250, F-350).
- Late 1970s–1980s: The F-Series stabilizes around the F-150 as the half-ton standard; body styles diversify (styleside, step-side, crew cab, etc.).
- Around the 1980s–1990s: The F-150 becomes Ford’s best-selling pickup for decades, maintaining the F-Series nomenclature in the U.S. market.
While regional variations and production nuances occurred, the 1975 relabeling remains the canonical turning point in the F-Series naming strategy.
What changed in practice
Practically, the switch altered how buyers perceived the lineup: a single, scalable naming scheme tied to payload simplified choices and aided Ford’s marketing efforts. The F-150 quickly became the default reference for half-ton pickups, a position it has retained in many markets for decades.
Other notes from the period:
- The F-150-era trucks offered similar engines and configurations to the F-100s they replaced, but with updated styling and options.
- The heavier-duty F-250 and F-350 retained their respective roles, continuing to serve three-quarter- and one-ton needs.
In short, the branding shift did more than swap badges; it set a long-lasting framework for Ford’s pickup lineup that remains in use today.
Summary
The switch from F-100 to F-150 occurred with the 1975 model year, when Ford introduced the F-150 as the light-duty successor to the F-100 and aligned the lineup around a half-ton payload concept. The F-250 and F-350 continued as the heavier-duty options, and the F-Series branding has endured for decades, remaining a cornerstone of Ford’s truck strategy and a staple in American automotive history.
What year did Ford go from F-100 to F-150?
Ford introduced the F-150 for the 1975 model year to sit alongside the F-100, and the F-100 was discontinued after the 1983 model year. The F-150 was created to offer a higher payload and help the company avoid certain emissions regulations that affected the F-100's load class.
- F-150 introduction: The F-150 was launched for the 1975 model year as a higher-payload version of the F-100 to navigate new emissions standards.
- Overlap period: Both the F-100 and F-150 were sold concurrently for nine years, from 1975 until 1983.
- F-100 discontinuation: Ford phased out the F-100 after the 1983 model year, making the F-150 the new entry-level half-ton truck in the F-Series lineup.
What is the difference between a F-100 and a F-150?
The main difference is that the F-150 was introduced in 1975 as a higher-payload version of the F-100, primarily to meet new emissions regulations by avoiding the need for a catalytic converter. This meant the F-150 had heavier-duty suspension, a higher Gross Vehicle Weight Rating (GVWR), and could use regular unleaded gas, while the F-100 could only use unleaded fuel and was a lighter-duty truck. The F-150 eventually replaced the F-100 completely after the 1983 model year.

|---|---|---|
| Payload/GVWR | Lighter duty, lower Gross Vehicle Weight Rating | Heavier duty, higher GVWR |
| Emissions/Fuel | Required unleaded fuel and emissions control devices like catalytic converters | Could use regular unleaded gas and avoided some emissions restrictions in its early years |
| Suspension | Standard suspension | Heavier springs and other heavier-duty components |
| Axles | 28-spline rear axles | 31-spline rear axles |
| Other components | Smaller brakes, lighter frame, and optional power brakes/steering | Larger brakes, potentially thicker frame, and more consistent power brakes/steering |
| Availability | Discontinued after the 1983 model year | Became the standard half-ton model and continues today |

Why did Ford change from F-100 to F-150?
In the midst of this generation, in 1975, Ford introduced the F-150 as an option designed to offer greater payload and muscle than the F-100 without going all the way up to the capabilities of the F-250.
When did Ford quit making the F-100?
In 1981, the upscale Ranger trim was discontinued to create the nameplate for the company's all- new compact pickup that replaced the Mazda-built Courier. Largely superseded by the F-150, the F-100 was discontinued after the 1983 model year, but the F-100 nameplate remained in Argentina.
