What do the Porsche Carrera GT, 550 Spyder, 918 Spyder, Boxster, and the 914 all have in common? Well, the Porsche badge of course, but more importantly they are all examples of mid-engine Porsches. When thinking of Porsche we generally ponder the iconic 911 with its rear-engine classic design, but there is a rich history of mid-engine cars in the Porsche past.
