Information on performance data for all-electric Porsche models

The maximum drive power of an all-electric vehicle is contingent on different factors compared to the maximum drive power of a vehicle with a combustion engine. In order to achieve the best possible comparability and reproducible results, Porsche determines the drive power of its all-electric models in accordance with the specifications of the UN Global Technical Regulation No. 21 (GTR21) and the UN ECE R-85.

The measurement of performance is carried out using a sufficiently charged battery on a temperature-controlled test stand. Maximum power is applied for the duration specified in the standard, which is 2 to 10 seconds, depending on the measuring method. The output is measured in Kilowatts and mathematically converted to Horsepower using factor 1.341.

With respect to Launch Control performance, GTR21 does not provide for measurements from a standing start. Therefore, to measure Launch Control performance, Porsche has slightly modified the measuring method and accelerated the vehicle from a standstill to a reference speed with Launch Control activated. The measurement starts as soon as the vehicle accelerates under full load.

The actual available drive power may be considerably lower than the maximum drive power measured on the test stand. Important influencing factors include the duration of the power requirement, speed, topography, the state of charge, and the temperature of the battery and related components.
