None Porsche 917

The Porsche 917 is an iconic race car that dominated the Le Mans circuit in the late 1960s and early 1970s. This mid-engine sports car was designed and built specifically for endurance racing and was considered one of the most powerful and agile cars of its time. Let's take a closer look at the technical specifications of this legendary machine.

The 917's bodywork was designed with aerodynamics in mind. The car sat low to the ground and had a sleek, aerodynamic shape. The entire body was made of lightweight materials, including aluminum and fiberglass, which helped to reduce the car's overall weight. The car was 4.2 meters long, 1.98 meters wide, and only 91 centimeters tall from the ground to the top of the roof.

The heart of the 917 was its engine, which was available in various configurations throughout its racing career. The initial engine used was a 4.5-liter, air-cooled flat-12 engine that produced up to 580 horsepower. This allowed the car to achieve speeds of over 240 miles per hour. Later versions of the engine were turbocharged, which increased power output to over 1,000 horsepower.

The transmission of the 917 was a five-speed manual gearbox with a dry-sump lubrication system. This system ensured that the car's engine and transmission remained properly lubricated during high-speed racing conditions. The car also featured four-wheel disc brakes, which were considered state-of-the-art at the time of its production.

The suspension system of the 917 was designed to be lightweight and responsive. The car featured a fully independent suspension on all four wheels, which allowed for superior traction and handling. The suspension system also included adjustable dampers and anti-roll bars, which allowed drivers to fine-tune the car's handling based on the track they were racing on.

One of the most significant features of the 917 was its innovative chassis design. The car featured a tubular space frame made of light and strong aluminum alloy. The frame was designed using advanced engineering techniques to ensure maximum stiffness, strength, and weight savings.

Overall, the Porsche 917 was an engineering marvel that set new standards for performance and technology in endurance racing. It was a true icon of its time and remains one of the most successful race cars in history. Its development and racing career helped to pave the way for many of the high-performance sports cars we see on the roads today.
