Ford Mustang III 4.9 V8 (228 Hp)

Introduction to the Ford Mustang III 4.9 V8 (228 Hp)

The Ford Mustang, an undisputed icon of American automotive culture, entered its third generation in 1979, a lineage often affectionately referred to as the “Fox Body.” This generation marked a significant departure from its predecessors, moving towards a more contemporary and aerodynamic design while retaining the essential spirit of accessible performance. The specific iteration, the Ford Mustang III 4.9 V8 (228 Hp), produced from 1983 to 1993, represents a pivotal moment in the Fox Body’s history, particularly for its re-establishment of the V8 engine as a true performance contender after the challenges of the 1970s.

Launched in 1983, this particular model year and engine combination brought a much-needed injection of horsepower and torque to the Mustang lineup, solidifying its position in the highly competitive pony car segment. It was a direct response to market demands for more exhilarating performance, a trend that was slowly but surely re-emerging after years of emissions regulations and fuel crises had stifled automotive power. The Fox Body platform itself was celebrated for its lightweight construction, versatility, and excellent handling characteristics, making it a favorite among enthusiasts for both street driving and motorsports. The 4.9 V8 variant, in particular, became synonymous with the resurgence of American muscle, offering a compelling blend of raw power and a relatively compact, nimble package for its era.

Powertrain and Performance: The Heart of the Ford Mustang III

The Robust 4.9 V8 Engine

At the core of the Ford Mustang III‘s appeal was its venerable 4.9-liter (301.58 cubic inch) V8 engine. This naturally aspirated, multi-port manifold injected powerhouse was a direct descendant of Ford’s long-standing small-block V8 family, refined for the 1980s to deliver a more potent and efficient output than its immediate predecessors. Producing a robust 228 horsepower at 4200 revolutions per minute (rpm) and a substantial 300.19 lb.-ft. of torque at a lower 3200 rpm, this engine provided the Mustang with formidable acceleration and a thrilling exhaust note that was quintessential V8.

The engine featured a classic V-engine configuration with eight cylinders, each equipped with two valves, a design known for its durability and torque delivery. Its front, longitudinal layout contributed to the car’s balanced weight distribution and traditional rear-wheel-drive architecture. With a bore of 4 inches and a stroke of 3 inches, coupled with a 9:1 compression ratio, the engine was optimized for a blend of power and everyday drivability, running on readily available gasoline. The inclusion of multi-port manifold injection, rather than a carburetor, was a significant technological upgrade for its time, improving fuel atomization, throttle response, and overall engine efficiency, albeit still far from modern standards.

Driving Dynamics and Performance Figures

Power was channeled to the rear wheels via a standard 5-speed manual transmission, offering drivers an engaging and direct connection to the car’s performance. This combination allowed the Ford Mustang III 4.9 V8 (228 Hp) to achieve a top speed of 136.7 mph, a highly respectable figure for a mainstream performance car of the early 1980s. The car’s kerb weight of 3042.38 lbs resulted in a weight-to-power ratio of 6.1 kg/Hp (or approximately 13.45 lbs/Hp), underscoring its ability to deliver spirited acceleration.

While performance was a priority, fuel economy, though not stellar by today’s standards, was also a consideration. The 4.9 V8 achieved an estimated 11.8 US mpg in urban driving conditions and a more palatable 19.6 US mpg on the highway, reflecting the compromises inherent in a large displacement V8 engine from that era. The 15.32 US gallon fuel tank provided a decent cruising range. The hydraulic power steering, utilizing a steering rack and pinion system, offered precise control, while the inclusion of an Anti-lock Braking System (ABS) was an advanced safety feature for its time, enhancing braking performance and stability.

Design and Features: The Iconic Fox Body Silhouette

The Ford Mustang III, known universally as the Fox Body Mustang, introduced a design language that was a radical departure from the larger, more ornate Mustangs of the 1970s. Its sleek, aerodynamic profile, characterized by sharp lines and a relatively compact footprint, defined a new era for the pony car. The specific model detailed here is a classic 2-door coupe, designed to seat four occupants, embodying the traditional sports coupe aesthetic.

Measuring 179.53 inches in length, 68.31 inches in width, and 51.97 inches in height, with a wheelbase of 100.59 inches, the Fox Body was a well-proportioned vehicle that struck a balance between road presence and agility. The front and rear track widths of 56.69 inches and 57.09 inches, respectively, contributed to its stable stance. The design prioritized functionality, with a relatively low cowl and large glass areas providing good visibility. The trunk space was surprisingly generous for a coupe, offering 30.02 cubic feet of cargo volume, making it more practical than some of its predecessors.

From a features standpoint, the 1983 Ford Mustang III 4.9 V8 offered a blend of performance-oriented equipment and emerging technologies. Standard disc brakes on both front and rear axles provided confident stopping power, further augmented by the optional or standard ABS, a significant safety advancement for the early ’80s. The suspension system, featuring coil springs at both the front and rear, was tuned to provide a sporty yet compliant ride. The 225/55 ZR16 tires provided ample grip, reflecting the car’s performance aspirations. Inside, the cabin was driver-focused, with instrumentation designed for clear readability and controls placed within easy reach, reflecting the pragmatic approach to performance that defined the Fox Body era.
