DFI injects fuel directly into the combustion chamber at up to 120 bar with millisecond precision using electromagnetic injectors. The injector position and spray geometry have been carefully designed to improve output, torque, fuel economy and emissions. The swirling of the fuel as it enters each chamber increases the mixing of air and fuel, thereby enhancing combustion. By forming the air/fuel mixture directly in the combustion chamber, DFI contributes to engine cooling. As a result, it was possible to increase the compression ratio and therefore power and efficiency.

Fuel consumption* of the Cayenne models: Urban in l/100 km (mpg): 15.8 (17.9)-8.4 (33.2); Extra urban in l/100 km (mpg): 8.4 (33.6)-6.5 (43.5); Combined in l/100 km (mpg): 11.5 (24.6)-7.2 (39.2); Emissions in g/km: 270-189.

* The latest Porsche models are designed to operate on fuels with an ethanol content of up to 10%. Data determined for standard specification and in the NEDC (New European Driving Cycle) in accordance with the Euro 5 (715/2007/EC and 692/2008/EC) measurement method. The figures do not refer to an individual vehicle nor do they constitute part of the offer. They are intended solely as a means of comparing different types of vehicle. You can obtain further information about individual vehicles from your Porsche Centre.

Consumption figures were obtained on the basis of standard equipment. Special equipment may affect consumption and performance.
