The Ford Bronco is a sports utility vehicle (SUV) manufactured and marketed by Ford from 1966 to 1996, over five generations. The Bronco was introduced in 1966 as a competitor to the small four-wheel-drive compact SUVs that included the Jeep CJ-5 and International Harvester Scout, and it was built on its own platform. A major redesign in 1978 moved the Bronco to a larger size, using a shortened Ford F-Series truck chassis to compete with both the similarly adapted Chevy K5 Blazer, as well as the Dodge Ramcharger. Most Broncos are usually equipped with a Spare tire swing away carrier found on the outside of the rear end door.
