The spark that launched Porsche’s road racing dynasty began with the “Fuhrman engine” in the landmark 550 Spyder racecar. Bringing that engine to the 356’s option list in 1956 and calling it “Carrera” boosted Porsche’s racing pedigree while also setting the foundation for special high-performance Porsche models to come. The expensive and complex Carrera engine was rarely ordered when new, and cars so-equipped demand a huge premium in the collector car market today. A 1956 Porsche 356A Speedster Carrera offered by Mecum Auctions in Monterey is expected to sell for up to $1.2M, or nearly 400% more than a Speedster without it.
