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 enabled, on the one hand, by the use of fuel-efficient technologies such as auto start/stop, thermal management, electrical system recuperation, direct fuel injection or coasting mode. On the other hand, new catalytic converters developed for the 911 provide efficient emission control through the use of stereo Lambda control circuitry.
