Medium duty line of trucks manufactured by Ford

The medium duty version of the Ford F Series is a range of commercial trucks manufactured by Ford Motor Company since 1948. Derived from the smaller F Series pickup trucks, the medium duty range is currently in its eighth generation. Initially slotted between the F Series pickup trucks and the "Big Job" conventionals, later generations were slotted below the L Series "Louisville" trucks; the last two generations are the largest vehicles produced by Ford since its exit from the heavy truck segment. The medium duty F Series has been used for an extensive number of applications, offered as a straight (rigid) truck and a truck tractor (for semitrailers) in multiple cab configurations. Prior to the production of the Ford C Series, the model line was also offered in a cab over engine (COE) configuration; a cowled chassis variant (the Ford B series) was used for bus production. For the 2000 model year, the medium duty F Series has been branded as part of the Ford Super Duty range, consisting of the Class 6–7 Ford F 650 and F 750; Class 8 versions of the F 750 have been produced since 2011. The current generation of the medium duty F Series is manufactured by Ford in its Ohio Assembly facility (Avon Lake, Ohio), replacing a joint venture with Navistar International named Blue Diamond Truck Company LLC located in General Escobedo, Mexico.

For the 1948 model year, Ford introduced the F Series as a dedicated truck platform. Along with replacing the trucks introduced before World War II, the F Series expanded Ford trucks into several product ranges. Along with light duty trucks, the medium duty range was slotted below the "Extra Heavy Duty"/"Big Job" commercial trucks

The medium duty F Series was marketed as a 1½ ton F 5 and 2 ton F 6, in both conventional and cab over engine (COE) configurations. The F 5 and F 6 also served as the basis for the B Series bus chassis; produced primarily for school bus use, the B series was a bare chassis aft of the firewall. Shared with the light duty F Series, the F 5 was powered by a 226 cubic inch inline six with a 239 cubic inch V8 as an option. For the 1951 model year, the medium duty F Series received a facelift, including a new grille. Through 1951, a 254 cubic inch inline six was optional for the F 6; for 1952, the 226 was replaced by a 215 cubic inch inline six.

Coinciding with the 50th anniversary of the Ford Motor Company, the second generation F Series was released for 1953. Alongside the vehicle redesign, the series nomenclature underwent a revision, with the F 5 and F 6 becoming the F 500 and F 600, respectively. The medium duty range retained both conventional and COE cab configurations, as a tractor, straight truck, or bus chassis. For 1956, F Series medium duty trucks shared the cab redesign of the light duty trucks, including its wraparound windshield and vertical A pillars. For 1954, Ford ended production of the long running Flathead V8, replacing it with a 239 cubic inch Y block V8; the 215 cubic inch inline six was expanded to 223 cubic inches. For 1956, the V8 was expanded to 272 cubic inches.

For the 1957 model year, the third generation F Series was released; medium duty trucks introduced multiple design features that would remain part of the model line (in various forms) over the next two decades. The clamshell hood returned, but was enlarged to the width of the fenders. In another change, the grill was also enlarged, eliminating the gap between the hood and bumper. For 1958, quad headlights were introduced (following their legalization). A 223 cubic inch inline six was offered as a standard engine. The Ford Y block was carried over from the previous generation, expanded to 292 cubic inches for 1958. The medium duty model line was reduced by one, as the F Series COE (C Series) was replaced by the Ford C Series tilt cab COE. Offering better egress and engine access, the tilt cab design was produced for a single generation through the 1990 model year (one of the longest running designs ever produced by Ford).

The fourth generation F Series had the medium duty trucks adopt the larger and wider cab introduced by the pickup trucks. In place of sharing drivetrains with light duty Ford trucks, the medium duty Ford trucks were fitted with six cylinder and V8 engines developed specifically for truck use. The model range was expanded, with the F 700/750 shifted from the heavy duty range to the medium duty range. The fourth generation marked the final generation that medium duty trucks shared bodywork with the light duty Ford F Series. For 1961, F 800 and above trucks were given their own fascia (with a central slotted grille). A Mercury version of this truck was also offered in Canada.

The fifth generation F Series was introduced for the 1967 model year, with Ford diverging the design of its light duty and medium duty F Series. To streamline production costs, medium duty trucks (and bus chassis) retained the cab and hood of light duty trucks. In place of the Twin I Beam suspension, a solid front axle was retained; redesigned front fenders to accommodate a wider front track (and larger wheels) were used. In another change, the stand alone T series designation for tandem axle trucks (T 700 and above) was withdrawn. In 2012, Ford introduced gasoline and gaseous (propane) engines for medium duty trucks.

For the 2016 model year, Ford introduced an eighth generation of its medium duty truck line. Following the 2015 dissolution of the Blue Diamond Truck joint venture, Ford shifted medium duty truck production from Mexico to its Avon Lake, Ohio assembly plant, alongside E Series cutaway van chassis and F 53/F 59 motorhome/commercial stripped chassis. As before, the F 650 and F 750 make a return, extending into the Class 7 range. The six speed 6R140 automatic transmission is the sole transmission for both engines; no manual transmission is offered. Ford reintroduced the F 600, a heavier duty version of the F 550, which is equipped with more reinforced U joints, frame, and front axle and powertrain of the medium duty F 650 while using the aluminum cab structure and frame design of the F 250 through F 550.
