The Ford Bronco III, produced between 1980 and 1986, represented a significant downsizing and repositioning of the iconic Bronco model line. Following the larger, full-size Bronco, the Bronco III was designed to compete in the burgeoning compact SUV market, offering a more fuel-efficient and maneuverable alternative. The 5.0L V8 engine paired with an automatic transmission was a mid-range offering within the Bronco III lineup, positioned above the base four-cylinder models but below potential future high-performance trims that never materialized. It was built on a shortened Ford F-150 chassis, utilizing a body-on-frame construction, and aimed to provide a blend of off-road capability and on-road comfort.

Powertrain & Engine Architecture
The heart of this Bronco III variant is the Ford 302 cubic inch (4.9L) small-block V8 engine. This engine, designated as the 302, is a 90-degree V-engine with a cast iron block and aluminum cylinder heads. The 152 horsepower output at 3400 rpm and 366 Nm (270 lb-ft) of torque at 2000 rpm were achieved through a multi-port fuel injection system, a significant upgrade over the carbureted engines of earlier Broncos. The engine utilizes a two-valve per cylinder configuration and a relatively conservative 8.9:1 compression ratio. The automatic transmission paired with this engine was typically a Ford C6 three-speed automatic, known for its durability and simplicity. This transmission was chosen for its ability to handle the V8’s torque and provide reasonable performance in both on- and off-road conditions. The engine is longitudinally mounted, driving all four wheels through a transfer case.
Driving Characteristics
The 5.0L V8 and automatic transmission combination in the Bronco III offered a noticeable step up in performance compared to the base four-cylinder models. While not a high-performance machine, the V8 provided adequate power for highway cruising and moderate off-road excursions. The automatic transmission, while smooth, did contribute to some power loss compared to a manual transmission. The C6’s gear ratios were optimized for torque delivery rather than outright acceleration. Real-world driving revealed a vehicle that felt capable and comfortable, but not particularly quick. The automatic transmission’s shift points were calibrated for fuel economy and smooth operation, sometimes feeling sluggish during quick acceleration. The all-wheel-drive system provided enhanced traction in slippery conditions, making it a capable vehicle in snow and mud.
Equipment & Trim Levels
The 5.0L V8 Automatic Bronco III typically came with a moderate level of standard equipment. Interior features generally included cloth upholstery, a basic AM/FM radio, and a heater/defroster system. Optional extras included air conditioning, upgraded sound systems, and a tilt steering wheel. The dashboard layout was functional but relatively spartan, reflecting the Bronco III’s focus on practicality rather than luxury. Exterior features typically included a black plastic grille, steel wheels, and basic exterior trim. The trim level associated with the 5.0L V8 was generally considered a step above the base models, offering a more comfortable and refined driving experience.
Chassis & Braking
The Bronco III utilized a traditional body-on-frame construction, providing a robust and durable chassis. The front suspension consisted of independent coil springs, while the rear suspension employed leaf springs. The rear brakes were typically drum brakes, while the front brakes were disc brakes. This configuration was common for vehicles of this era and weight class. Stabilizer bars were often included to reduce body roll during cornering. The relatively high ground clearance of 234 mm (9.21 in.) contributed to the Bronco III’s off-road capability. The tires, typically 235/75 R15, were chosen for a balance of on-road comfort and off-road traction.
Market Reception & Comparison
The Bronco III 5.0L V8 Automatic received mixed reviews from automotive critics. While the V8 engine was praised for its power and smoothness, the automatic transmission was sometimes criticized for its lack of responsiveness. Fuel economy was a common concern, with the 15.7 l/100 km (15 US mpg) combined fuel consumption being relatively high for the time. Compared to the four-cylinder Bronco III models, the V8 offered significantly improved performance but at the cost of increased fuel consumption. Compared to other compact SUVs of the era, such as the Chevrolet S-10 Blazer and the Jeep CJ, the Bronco III offered a unique blend of off-road capability and on-road comfort.
Legacy
The Ford Bronco III, particularly the 5.0L V8 Automatic variant, has developed a loyal following among classic Ford enthusiasts. The 302 V8 engine is known for its reliability and ease of maintenance, making it a popular choice for restoration projects. While not as collectible as the earlier full-size Broncos, the Bronco III offers a more affordable entry point into the world of classic Ford SUVs. The automatic transmission, while not as desirable as a manual transmission to some enthusiasts, remains relatively durable and reliable. Today, well-maintained examples of the Bronco III 5.0L V8 Automatic can command respectable prices in the used car market, reflecting their growing popularity and historical significance.
