Porsche Macan S - Fuel system

Fuel system

Fuel and fuel consumption

Doing more with comparatively less – another philosophy that the new Macan models live and breathe. The petrol models are designed to operate on fuels with an ethanol content of up to 10%. Ethanol has a positive impact on the CO2 balance because this biofuel is manufactured from plants, which absorb CO2 from the atmosphere in order to grow.

Fuel system

In the petrol models, even the emissions of the fuel system itself are minimised for the protection of the environment. Evaporative emissions are significantly reduced by the returnless supply system. Vapour-carrying lines are made from multi-layered plastic, while a high-capacity active carbon filter and the fuel tank also feature a multi-layered construction in order to make everything as impermeable as possible.
