Data determined in accordance with the measurement method required by law. As of 1 September 2018 the Worldwide Harmonised Light Vehicles Test Procedure (WLTP) replaced the New European Driving Cycle (NEDC). Due to the more realistic test conditions, the fuel/electricity consumption and CO₂ emission values determined in accordance with the WLTP will, in many cases, be higher than those determined in accordance with the NEDC.
Currently we are still obliged to provide the NEDC values, regardless of the type approval process used. The additional reporting of the WLTP values is voluntary. As all new cars offered by Porsche are type approved in accordance with the WLTP, the NEDC values are therefore derived from the WLTP values. To the extent that the values are given as ranges, they do not relate to a single, individual car and are not part of the offer. They are intended solely as a means of comparing different types of vehicles. Optional equipment and accessories (attachments, tyre formats etc.) can change relevant vehicle parameters such as weight, rolling resistance and aerodynamics and, along with weather and traffic conditions and individual handling, can affect the fuel/electricity consumption, CO₂ emissions, range and performance figures of a car.
You can find more information on the difference between WLTP and NEDC at www.porsche.com/wltp.
Further information on the official fuel consumption and official, specific CO₂ emissions of new passenger cars is available in the “Guidelines on fuel consumption, CO₂ emissions and power consumption of new passenger cars” [Leitfaden über den Kraftstoffverbrauch, die CO₂-Emissionen und den Stromverbrauch neuer Personenkraftwagen], available free of charge from all sales outlets and from Deutsche Automobil Treuhand GmbH (DAT).
