Exhaust emission control
Models shown: 911 Carrera 4S Cabriolet, 911 Carrera 4 Cabriolet
Vehicles manufactured by Porsche demonstrate that even high-performance sports cars can achieve moderate fuel consumption and exhaust emission values in their respective category.
This is achieved, on the one hand, through the use of fuel-efficient technologies such as auto start/stop, thermal management, electrical system recuperation, direct fuel injection, VarioCam Plus and, in conjunction with optional PDK, coasting mode.
On the other hand, new catalytic converters developed for the 911 provide efficient emission control.

The stereo Lambda control circuitry controls and monitors each cylinder bank separately. For each
exhaust tract, oxygen sensors regulate the composition of the exhaust gas, while another Lambda sensor on each cylinder bank monitors pollutant conversion in the respective catalytic converter.
Fuel economy and recycling
Model shown: 911 Carrera 4
Intelligent lightweight construction has been fundamental to the Porsche identity since 1948, for both technical and ecological reasons. This forms the basis for achieving low fuel consumption values in conjunction with outstanding performance.
On the technical side, we use a high proportion of aluminum, magnesium, plastics and super-high-strength sheet steel. The materials used have been selected for their ability to withstand load, yet they are considerably lighter than conventional steel.
On the ecological side, all materials used are meticulously selected. All synthetic components are easily recoverable and each material is labeled to facilitate its separation for recycling. The reduction in the number of plastic variants helps to ensure more efficient recycling. Recycled

plastics are used where they meet our exacting technical requirements.
In short, the 911 is around 95 % recoverable.
In addition, Porsche uses a high proportion of environmentally friendly water-based paints. For us, environmental protection does not begin at the end of a vehicle’s life. It starts at the planning and development stage.

Fuel
Model shown: 911 Carrera 4
All Porsche models – including the 911 – are designed to operate on fuels with an ethanol content of up to 10%, e.g. ‘E10’. Ethanol has a positive impact on the CO2 balance since the plants grown for the production of this biofuel also absorb CO2 from the atmosphere.
The release of hydrocarbons from the fuel system has been minimized thanks in no small part to the active carbon filter and the multilayered material from which the fuel tank is made. All fuel lines are made from multilayered plastic, steel or aluminum.
