The second generation of Ford Bronco was introduced for the 1978 model year. The second generation Bronco saw the model move to the full-size segment, whereas it had been a compact SUV previously. The Bronco was now based on the Sixth Generation F-Series F-100, and was only an inch shorter than the model it was based on. This latest generation was only offered as a three door SUV, and was only available in four wheel drive. Two V8 engine options were offered, a 5.8L unit or a 6.6L V8, and while both units had about the same power, the larger 6.6L unit featured greater torque. The second generation Bronco was short lived, with the production lasting until 1979, when it was replaced by the Third Generation Ford Bronco.
