Porsche Fuhrmann
As one of Porsche’s first air-cooled boxer engines, the Porsche Fuhrmann engine, also known as the Porsche Type 547 engine, has played a significant role in its development. Porsche engineer Ernst Fuhrmann oversaw its development and powered the iconic Porsche 550 Spyder and 356 Carrera. What made the Fuhrmann engine unique was its advanced design and technology, which included four camshafts and two spark plugs per cylinder (via Porsche).

This allowed the engine to produce more power, rev higher, and run smoother than previous air-cooled boxer engines. The Fuhrmann engine is reliable and durable. The simple design of the engine is what makes it special. It was a popular choice among sports car enthusiasts and racers. The Type 547 engine set the foundation for the air-cooled Porsche engine design. The engine design continued to evolve and improve over the years.
