The second generation of the Porsche Carrera 997, Boxster 987 and Cayman sees the introduction of a new family of water-cooled flat-six engines at Porsche. These engines represent a completely new design, which is characterised by a modular concept, several displacement variants and higher degree of integration with enhanced power unit rigidity. The engine family is structured to reflect the typical Porsche differentiation between the individual vehicle types in economic terms. The power output of the new flat-six engines ranges from 188 kW to 283 kW. The characteristics which are key for a high performance engine, such as a wide engine speed range, spontaneous responsiveness, low weight with a low centre of gravity and high lateral acceleration, have all been significantly improved in comparison with the predecessor engines. Performance and fuel consumption levels unmatched by competitors have been achieved thanks to the first-ever use of direct fuel injection in a flat-six engine, coupled with consistently enhanced cylinder charging and reduction of internal engine friction.
