Certain manufacturers of motor vehicles become synonymous with specific areas of the car world. Pagani builds supercars, Rolls-Royce focuses on ultimate luxury vehicles, and Morgan makes weird wooden three-wheelers, but there are few brands as inextricably linked to a class of car as Porsche is to the sports car. The Stuttgart brand has been at the forefront of the sports car market for over 50 years now, offering some of the very best vehicles in the class, and breaking boundaries of performance, with some models, such as the 911, becoming iconic in its own right and part of the brand's identity.
