1965 Porsche 904/6 Prototype

The Porsche 904/6 Prototype 1965, also known as the Carrera GTS, is a legendary race car that was produced in a limited number. This car is an evolution of the Porsche 718 and was developed by Porsche's racing division to compete in GT class racing. It was first unveiled at the 1963 Frankfurt Auto Show and was an instant sensation for sports car enthusiasts.

The 904/6 Prototype 1965 is powered by a 2.0-liter, air-cooled six-cylinder engine that produces 210 horsepower. The engine features 9.8:1 compression ratio, dual overhead camshafts, and a four-speed manual transmission that delivers power to the rear wheels. With a lightweight chassis and aerodynamic body, the car can achieve a top speed of 160 mph.

The chassis of the Porsche 904/6 Prototype was made from a combination of steel and aluminum, which made it both strong and light. The fiberglass body was designed with the help of wind tunnel testing to reduce drag and increase downforce. The car weighs just 1,433 pounds, which is incredibly light for a racing car of its time.

The suspension of the 904/6 Prototype features an independent suspension system with unequal length A-arms, coil springs, and tubular shock absorbers on all four corners. The front suspension utilizes an anti-roll bar to help minimize understeer. The rear suspension has a transversely mounted leaf spring, which provides excellent stability during high-speed cornering.

The car's brakes are disc brakes on all four corners, which was still a relatively new technology at the time. The disc brakes help provide excellent stopping power, even at high speeds. The car's wheels are lightweight magnesium alloy, which has been specially designed to reduce weight and provide better aerodynamics.

Inside the car, the Porsche 904/6 Prototype features a minimalist interior with lightweight bucket seats, a sports steering wheel, and a comprehensive dashboard with all the necessary gauges. The car's dashboard features an oil temperature gauge, oil pressure gauge, water temperature gauge, fuel gauge, speedometer, and tachometer. The car also features a roll bar for safety measures.

Overall, the Porsche 904/6 Prototype 1965 is a masterpiece of engineering, with a lightweight chassis, aerodynamic body, and powerful engine. The combination of advanced technologies used in this car helped to establish Porsche's reputation as a pioneering sports car manufacturer. This car is a true icon of the golden age of racing, and it still holds a special place in the hearts of sports car enthusiasts today.
