The Porsche Boxster is the direct translation of probably the most classic of all roadster concepts with unmistakable Porsche styling. It embodies a unique combination of rational and emotional aspects. The Boxster combines classic characteristics with modern features, power with elegance, dynamism with design. And, because it is a Porsche, it represents driving enjoyment and suitability for day-to-day use as well as the symbiosis of active and passive safety like no other roadster. Although its design is bound to tradition, its implementation is always oriented to the technologically feasible. Engine Type Six cylinder, horizontally opposed, water-cooled Bore 3.4 in.
