It captivated a generation with its potent 7.0-liter V8 engine, sophisticated yet muscular design, and the allure of open-air motoring, cementing its place as an enduring icon in automotive history.

Engine and Performance: The Heart of the Cobra GT 500

At the core of the Ford Shelby I Cabrio Cobra GT 500 7.0 V8 (365 Hp) Automatic lay its formidable powertrain, a testament to American V8 engineering prowess. The vehicle was powered by a massive 7.0-liter (6997 cm³ or 426.98 cubic inches) V8 engine, a unit that delivered a thrilling 365 horsepower at 5400 rpm. This colossal engine, configured longitudinally at the front of the vehicle, was a naturally aspirated marvel, drawing its fuel through a robust carburetor system – a common and highly effective setup for performance cars of its time.

Torque, the true measure of a muscle car’s grunt, was equally impressive, peaking at a staggering 419.67 lb-ft (569 Nm) at a relatively low 3200 rpm. This immense torque ensured instant acceleration and a thrilling surge of power across the RPM band, making the Cobra GT 500 a formidable presence on both the street and the drag strip. The engine featured an 8-cylinder V-configuration with 2 valves per cylinder, a bore of 4.13 inches (104.9 mm), and a piston stroke of 3.98 inches (101.19 mm), all contributing to its robust and durable nature. A compression ratio of 10.5:1 further enhanced its power output.

Power was efficiently channeled to the rear wheels via a 3-speed automatic transmission. While some purists might argue for a manual gearbox, the automatic transmission in the Cobra GT 500 was engineered for smooth, rapid shifts, allowing drivers to focus on the road ahead without the distraction of clutch work. This setup made the immense power more accessible and easier to manage, catering to a broader audience while still delivering exhilarating performance. With a curb weight of 3659.67 lbs (1660 kg), the car boasted a favorable weight-to-power ratio of 4.5 kg/Hp (219.9 Hp/tonne) and a weight-to-torque ratio of 2.9 kg/Nm (342.8 Nm/tonne), underscoring its impressive performance metrics for a vehicle of its stature and era. The fuel tank capacity of 16.91 US gallons (64 liters) provided a decent range for cruising, though spirited driving would undoubtedly see more frequent stops at the pump.

Design and Features: An Icon of American Styling

The Ford Shelby I Cabrio Cobra GT 500 7.0 V8 (365 Hp) Automatic was more than just a powerhouse; it was a visual spectacle. As a two-door cabriolet with seating for four, it combined the thrill of open-air driving with the aggressive aesthetics of a high-performance machine. The design language of the Shelby I Cabrio was an evolution of the iconic Mustang, infused with Carroll Shelby’s distinctive performance cues.

Measuring 186.61 inches (4740 mm) in length, 70.91 inches (1801 mm) in width, and 51.42 inches (1306 mm) in height, the car possessed a commanding presence. Its long hood, short deck, and muscular fenders were instantly recognizable. Unique Shelby design elements included the distinctive front grille with integrated driving lights, functional hood scoops for engine cooling, side scoops for brake cooling, and a fiberglass trunk lid with an integrated spoiler. The prominent Cobra GT 500 badging, often featuring the iconic snake emblem, proudly announced its pedigree.

The interior, while focused on performance, offered a comfortable and engaging driving environment. Period-correct features included high-back bucket seats, a wood-rimmed steering wheel, and a full complement of gauges to monitor engine vitals. The overall ambiance was one of purposeful luxury, a blend of performance and refinement. From a mechanical standpoint, the Shelby I Cabrio featured a robust drivetrain architecture where the internal combustion engine drove the rear wheels, ensuring classic muscle car handling characteristics. The front suspension typically comprised independent wishbones, while the rear featured a solid axle with leaf springs, a common and durable setup for the time. Braking was handled by disc brakes at the front, offering superior stopping power, complemented by drum brakes at the rear. These features, combined with a wheelbase of 107.99 inches (2743 mm) and a minimum turning circle of 38.06 feet (11.6 m), contributed to a dynamic and engaging driving experience, characteristic of the era’s performance convertibles.
