The current 911 Turbo generation is already compatible with fuels that have an ethanol content of up to 10 %. A ‘biofuel’ made from naturally replenishing materials, ethanol has a positive impact on the carbon dioxide balance since the plants grown for its production also absorb carbon dioxide from the atmosphere.

Hydrocarbon emissions from the fuel supply system are low, achieved through a combination of an active carbon filter and a special fuel-tank coating. All fuel lines are made from aluminium, whilst those carrying vapours are made from multi-layer plastic.
