Porsche 911 GT3 - Emission control

Emission control

The new 911 GT3 meets the strict EU and LEV II standards. Vehicles manufactured by Porsche demonstrate that even high-performance sport cars can achieve moderate emission values in their respective category. This puts the new 911 GT3 among not only the most powerful sport cars of the future, but also the cleanest.

This has been accomplished not least by the two catalytic converters and stereo Lambda control circuits, which monitor each cylinder bank separately. For each exhaust tract, two Lambda sensors regulate the composition of the exhaust gas. Another Lambda sensor for each cylinder bank monitors pollutant conversion in the respective catalytic converter.
