The Porsche 356 represented the company's original sports car, established in 1948 and remaining in continuous production through 1965. The first Porsche employed a 1.1-liter air-cooled horizontally-opposed four-cylinder engine producing 40 horsepower initially, with progressive displacement increases to 1.6 liters and power outputs exceeding 100 horsepower in final variants. The 356 established air-cooled rear-engine philosophy as Porsche's defining design principle, a tradition that would persist through the company's entire sports car portfolio for over fifty years.
