Summary

At 48 years of age, the new Porsche 911 Carrera is younger than ever. The completely redeveloped generation of the Sports Car icon has raised the bar for performance and efficiency even higher. All versions boast fuel consumption of less than ten litres per 100 kilometres. Fuel consumption and emissions are reduced by up to 16 percent compared with the predecessor. A significant contribution to this is made by the extensively optimised flat-six engines. The performance of the 3.8-litre engine in the 911 Carrera S was increased to 400 hp through further dethrottling of the intake section and the exhaust system in conjunction with optimisation of the combustion process, while consumption was reduced by 15 percent through use of the Porsche Doppelkupplung (PDK).
