Porsche has increased the gross capacity of the high-voltage battery in the Cayenne E-Hybrid to 17.9kWh from 14.1kWh, an increase of up to 30%. This means the Cayenne E-Hybrid can now cover up to 48km with no emissions, while the Turbo S E-Hybrid covers up to 42km.
The purely electric powertrain in all plug-in hybrid Cayenne models comprises an electric motor integrated into the eight-speed Tiptronic S automatic transmission. This powertrain delivers an output of 134bhp and 400Nm of torque, generating a purely electric top speed of 135km/h.
In the Cayenne E-Hybrid, this is a turbocharged 3.0-litre V6 with an output of 335bhp, for a combined system output of 455bhp. The Cayenne Turbo S E-Hybrid models feature a 542bhp, 4.0-litre V8 bi-turbo engine, with a combined system output of 670bhp.
The driving modes of the standard Sport Chrono Package have been optimised to further improve efficiency and performance.
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. 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 more effectively at a higher, consistent charging power - at an average of 12kW on the Cayenne Turbo S E-Hybrid in Sport Plus mode, for example.
