Ford Bronco Shorthorn Prototype, 1973. In order to compete with the Chevrolet Blazer and Jeep Cherokee Ford began work on several Big Bronco Concepts during 1973. The Shorthorn was based on a shortened F-100 chassis which would significantly lower production costs by sharing running gear and body panels with Ford’s truck. The oil crisis of 1973 delayed production and the F-100 based second generation Bronco went on sale in 1978.
