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, 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.
