The earliest sketches for the Bronco, dated July 24, 1963 were developed by designer McKinley Thompson, and show the now familiar box-shaped vehicle with the recognizable round headlights and two-door layout. The one jarring feature of the early design documents was the placement of the spare tire inside the vehicle’s rear storage space! McKinley Thompson, was part of the larger team working on the Bronco, but stands out because he was the first African American automobile designer working for Ford.
The vehicle underwent constant revisions over the next year as its features were molded, so as Don Frey described it was “neither a conventional car nor a truck, but as a vehicle which combines the best of both worlds. It can serve as a family sedan, as a sports roadster, as a snow plow, or as a farm or civil defense vehicle. It has been designed to go nearly anywhere and do nearly anything.”
Initially, the Bronco was offered in three body styles, the Roadster (open air model), Sports Utility (with pickup bed,) and Wagon (two-doors, tailgate, full top.) The Roadster was the most basic and least expensive of the three with doors and roof as options! The Sports Utility featured a short top, seating for two or three with a bench seat and a pickup-style bed. Over time, the Sports Utility was known as the “half-cab.” The most popular model was the Wagon with a full-length hardtop roof and seating for up to five people with a rear bench seat. While there were a tremendous number of optional packages, all three models came with standard four-wheel drive, a 3-speed manual transmission, and a 105-horsepower 170-cubic-inch six-cylinder engine. On March 2, 1966, the 289-V-8 was offered as an upgrade and the Bronco’s horsepower and torque rating increased to the top of the sports-utility field.
While those were the basic specifications, Don Frey also signaled the available customization of the vehicle by noting “like its older brother, the Mustang, it will be offered with a wide range of options and accessories that will permit it to be the many things to many people.” The accessory catalogs for the first-generation Broncos read like an outdoorsman’s dream with equipment like snowplows, front-mounted winch, tow hooks, locking hubs, power take off and even two-way radios. The early advertising for Bronco reflects its outdoor use, and the customization and accessorizing of the vehicle. In essence, the Bronco became a palette that each owner could, and did, modify for their lifestyle. In its basic configuration, the Bronco was as comfortable on the highway as the trailhead, but with some modification, could win at Baja.
The Bronco was an immediate favorite for outdoor off-road racing. Bill Stroppe was given a Bronco before its public release and prepared it for competition. That six-cylinder Bronco was the overall winner at the 1967 Riverside Four-Wheel Drive Grand Prix. The Stroppe Broncos also racked up victories in 1968 at Riverside, the Mint 400, and Baja 1000, where Larry Minor and Jack Bayer drove a stock Bronco to victory in its class. In 1969 Minor and Rod Hall took the class and overall victory as their Bronco was the first vehicle of any kind to cross the finish line setting a new record. The off-road racing scene also attracted a number of celebrities who wanted to try their hand at racing Broncos. Actor James Garner and band leader Ray Coniff were just two who joined the Ford team. Possibly the most famous driver was Indianapolis 500 winner Parnelli Jones, who joined the Stroppe team as a driver. Their modified 1970 “Big Oly” Bronco soon became the talk of the Bronco community and is still arguably one of the best-known off-road racing vehicles of all time. Winner of the 1971 and 1972 Mexican 1000 Race, the Parnelli Jones Bill Stroppe driving partnership cemented the legends of both men.
While upgrades were made to the Bronco after its introduction in 1966, the vehicle remained essentially unchanged until 1973. That year the long awaited power steering and automatic transmission were introduced as part of a “Bronco Revolution.” When the 302 V-8 was selected buyers were able to choose the SelectShift Cruise-O-Matic 3-speed transmission. Additionally, a new 200-cubic inch six replaced the 170-cubic inch six that had been standard since the introduction.
