The Ford Bronco is a model line of SUVs that were manufactured and marketed by Ford from 1965 to 1996. After the first generation of the Bronco was introduced as a competitor to compact SUVs (including the Jeep CJ-5 and International Harvester Scout), the succeeding four generations of the Bronco were full-sized SUVs, competing against the Chevrolet K5 Blazer and Dodge Ramcharger. The first Bronco was assembled using its own chassis, while the full-sized Bronco was derived from the Ford F-Series (F-100, later F-150) pickup truck; all Broncos were produced with four-wheel drive powertrains.
