Porsche550

The Porsche 550 is a racing sports car produced by Porsche from 1953 until 1956. In that time only 90 Porsche 550s were produced, and they quickly established dominance in the 1.1- and 1.5- liter classes. The Porsche 550 is a mid-engine car with an air-cooled four-cylinder engine, following the precedent of the 1948 Porsche 356/1 prototype designed by Ferry Porsche. The mid-engine racing design was further developed with Porsche's 718 model; its advantages led to it becoming the dominant design for top-level racing cars by the mid-1960s.
