at the front was a new upper and lower A-arm suspension with coil springs. The first chassis completed was powered by a 547/3 four-cylinder engine with Kugelfischer fuel injection. At the Monaco Grand Prix the car retired when the fuel injection cut out. A second car, also fitted with the 547/3 engine, was completed in time to appear in the Dutch Grand Prix alongside the other 787. The cars placed 10th and 11th, but their lack of power and poor handling caused Ferry Porsche to retire the model. Porsche would focus on building a brand new competitive formula race car with an eight-cylinder engine. Design General The 804 was designed by Ferdinand Alexander "Butzi" Porsche, also known as F.A. Porsche. He is the son of Ferdinand Anton Ernst "Ferry" Porsche, and grandson of the company's eponymous founder Ferdinand Porsche. F.A. Porsche was assigned the project by the company's long-time chief body engineer Erwin Komenda. The design was done for Wilhelm Hild, an engineer with the racing department, and Hubert Mimler, another engineer who worked on a variety of projects at the company and who was assigned to the racing department at the time. The two engineers worked with FA Porsche on the car. Acting as Racing director at Porsche was Fritz "Huschke" von Hanstein. A total of four cars were built. The fourth chassis was never raced. The 804 gave Porsche its only F1 wins as a constructor, at the 1962 French Grand Prix, and at the (non-WC) Solituderennen at Castle Solitude in Stuttgart, both with Gurney as driver. A Porsche 804 is a part of the collection of the Porsche Museum. Following an eight-month long restoration, the car appeared at the Grand Prix Historique at Monaco in 2016. The car later appeared at the 2018 Goodwood Festival of Speed. Chassis and body Design of the 804's chassis was headed by Helmuth Bott, Porsche's chassis engineer. Like the Porsche 787 before it, the 804 had a tubular steel frame and an aluminum body, but the two vehicles differed significantly in appearance. The 804 was narrower and lower, with a smoother surface than its predecessor that was achieved in part by using a horizontal cooling fan (vertical axis) on top of the new flat-eight engine, in contrast to the vertically mounted (horizontal axis) cooling fan used on the four-cylinder Fuhrmann engine. The 804 was the first Porsche to have some factory
