The 1966 model year

Overview

Ford introduced the Bronco for 1966 as a compact, purpose-built four-wheel-drive utility vehicle. The factory brochure offered three distinct bodies—the open Roadster, short-roof Sports Utility, and fully enclosed Wagon—on a 92-inch wheelbase.

Year over year

What changed

  • Launch year of the Bronco as a compact 4x4 on a dedicated platform.
  • The Roadster came without roof or doors; Sports Utility added a short steel cab roof and metal doors; Wagon added a full-length roof and rear liftgate.
  • The 170-cubic-inch six was standard, the 289-cubic-inch V8 optional, and both used Ford's three-speed synchronized manual transmission.

Worth knowing

Notable

  • The brochure specifies a 92-inch wheelbase and 152.1-inch overall length.
  • All three launch bodies shared four-wheel drive and a two-speed Dana 20 transfer case.

Living with it

Reliability & ownership notes

  • Verify the body-model identity and engine before ordering parts: removable roofs and doors make surviving Broncos easy to reconfigure, while the original brochure defines three separate factory bodies.
  • Ford's specifications distinguish different clutch, spring, and axle equipment with the V8 and optional gross-vehicle-weight package, so the vehicle's original equipment record matters for chassis service parts.
