The Shelby GT500 R, produced in 1968, was one of the most iconic and powerful muscle cars of its time. It was the "R" version of the already popular GT500, carrying the same powerful engine but with some key technical upgrades.
Under the hood, the Shelby GT500 R featured a robust 428 cubic-inch V8 engine produced by Ford, capable of producing a staggering 450 horsepower. This engine was equipped with a Holley four-barrel carburetor and a unique dual exhaust system, resulting in an impressive torque rating of 520 lb-ft. The engine was mated to a four-speed manual transmission that transferred power to a limited-slip differential at the rear wheels.
The suspension system was specially designed for the Shelby GT500 R, featuring stiff springs and heavy-duty shock absorbers. The front suspension utilized a double-wishbone design, while the rear suspension featured a leaf spring setup. This unique suspension system provided excellent handling and stability at high speeds, making it the ideal car for drag racing.
The exterior of the Shelby GT500 R was also unique, with a distinctive Shelby front fascia, hood scoops, and rear spoiler. The car also had racing stripes running down the center and side of the vehicle, giving it a sporty and aggressive look. The car's body was made of fiberglass, which was not only lightweight but also gave the car a smooth and polished appearance.
Inside the car, the focus was on performance and functionality. The seats were high-backed bucket seats, finished in black vinyl with racing seatbelts. The dashboard featured a large speedometer and tachometer, along with temperature and oil pressure gauges. The car also had a wood-rimmed steering wheel, which added to the sporty style of the Shelby GT500 R.
Overall, the Shelby GT500 R was a technological masterpiece of its time, combining a powerful engine, unique suspension system, and striking exterior design. It is regarded as one of the most sought-after muscle cars ever produced and remains a true classic to this day.
