To improve fuel economy, the auto start/ stop function switches off the engine when you are coming to a stop at traffic lights, for example.

The coasting function enables you to save even more fuel where the situation allows. The engine is decoupled from the transmission, which avoids the deceleration caused by engine braking. In this way, the vehicle makes optimum use of its own momentum and is able to coast for longer distances. This has real benefits for fuel consumption without any impact on comfort or sporty performance.
Standard in all
Engine cooling is prevented during the initial stages of a cold start so that the engine reaches its optimum operating temperature faster. This means it can begin working at high efficiency sooner, thereby consuming less fuel.
The radiator grille shutter opens the cooling air flaps only as needed. Whenever the cooling requirement is low, such as on relaxed drives, the radiator grille shutter closes. Aerodynamics are improved, which helps to improve fuel economy. If, for example, a sporty driving style is adopted and the demand for power increases, the cooling air flaps will open and let in the necessary amount of cooling air for increased driving performance.
To enhance efficiency, the electrical system in the
* Data determined in accordance with the measurement method required by law. Since 1 September 2017 certain new cars have been type approved in accordance with the Worldwide Harmonised Light Vehicles Test Procedure (WLTP), a more realistic test procedure to measure fuel/electricity consumption and CO₂ emissions. As of 1 September 2018 the 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. This may lead to corresponding changes in vehicle taxation from 1 September 2018. You can find more information on the difference between WLTP and NEDC at www.porsche.com/wltp.
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 until their obligatory use. As far as new cars (which are type approved in accordance with the WLTP) are concerned, the NEDC values will, therefore, be derived from the WLTP values during the transition period. To the extent that NEDC values are given as ranges, these do not relate to a single, individual car and do not constitute part of the offer. They are intended solely as a means of comparing different types of vehicle. Extra features and accessories (attachments, tyre formats, etc.) can change relevant vehicle parameters such as weight, rolling resistance and aerodynamics and, in addition to weather and traffic conditions, as well as individual handling, can affect the fuel/electricity consumption, CO₂ emissions and performance values of a car.
