Innovations such as variable intake systems, variablecamshaft adjustment, intake valve lift switching, turbocharging - also with variableturbine geometry, crankcase with Fe-coated liners, as well as high-revvingconcepts have contributed that the history of the Porsche flat-six engine hasbeen successfully continued again and again. The latest revision with piezo directinjection proves that this engine concept can be successfully adapted tochanging requirements and that the advantages of the concept can be furtherexploited. Continuing this success story is one of the challenges of the future,especially in the face of CO_2 targets and requirements for exhaust gas cleaning. The drive systems must be lightweight, efficient and have a high revving stabilityto qualify for installation in a Porsche 911. Achieving a fine balance betweenday-to-day usability and motor sport, exclusivity and social acceptance, innovationand tradition as well as emotion and function is essential. The flat-six engineis not a power unit of yesterday, but forms the basis for the efficient sports engineof tomorrow. 收起
