Porsche Cayenne E-Hybrid models get a bigger battery pack


Porsche has increased the battery capacity of the Cayenne E-Hybrid models from 14.1 kWh to 17.9 kWh — the same capacity as the recently-updated Panamera E-Hybrid models, resulting in a 30% increase in pure electric driving range.

As per the WLTP EAER City cycle, the Cayenne E-Hybrid is claimed to now cover 48 km (29 mi), while the Turbo S E-Hybrid covers up to 42 km (26 mi). The NEDC ranges are 56 km (34 mi) and 53 km (32 mi), respectively.

No other big changes. The Cayenne E-Hybrid with its 3.0L V6 turbocharged motor and a powerful e-motor will deliver a combined 340 kW (462 metric hp), while the Cayenne Turbo S E-Hybrid models with a 4.0L V8 biturbo motor in combination with a powerful e-motor will offer 500 kW (680 metric hp) combined output.

Optimized driving modes for better efficiency
The driving modes of the standard Sport Chrono Package have been optimized to further improve efficiency and performance, Porsche said.

The E-Charge mode, in which the internal combustion engine charges the battery via load point shifting during a journey, now links to an adjusted charging strategy: The target state of charge of the battery has been reduced from 100 to 80%. Much like a smartphone battery, the battery charges much more slowly and inefficiently when the battery’s state of charge reaches approximately 80% or more. This strategy also provides a way of ensuring that full recuperation power is available at all times. The E-Charge mode is therefore even more efficient than it was before. In the performance-oriented Sport and Sport Plus modes, the battery is always charged to a minimum level to provide sufficient boost options for a sporty driving style, and it is now charged even more effectively at a higher, consistent charging power – at an average of 12 kW on the Cayenne Turbo S E-Hybrid in Sport Plus mode, for example.
