Porsche has increased the electric range of the plug-in hybrid Cayenne models, as part of a number of updates for the new 2021 Model Year. Underlining the commitment of the Stuttgart sports car manufacturer to E-Performance, the gross capacity of the high-voltage battery has increased to 17.9 kWh from 14.1 kWh. This has seen the electric range extend by up to 30 per cent. Measured in line with the WLTP EAER Combined cycle, the Cayenne E-Hybrid can now cover up to 25 - 27 miles using battery power, while the Turbo S E-Hybrid can cover up to 24 - 25 miles.
The purely electric powertrain in the plug-in hybrid Cayenne and Cayenne Coupé models comprises an electric motor integrated into the eight-speed Tiptronic S automatic transmission. This delivers an output of 100 kW (136 PS) and 400 Nm, generating a purely electric top speed of 83 mph. Any increased power demand from the driver or switching to the Sport or Sport Plus driving modes activates the internal combustion engine. In the Cayenne E-Hybrid, this is a three-litre V6 turbo with an output of 340 PS (250 kW), which contributes to a total system performance of 462 PS (340 kW).
The Cayenne Turbo S E-Hybrid models feature a 550 PS (404 kW), four-litre V8 twin-turbocharged engine, resulting in a total system power output of 680 PS (500 kW).
Optimised driving modes for greater efficiency
The driving modes of the standard Sport Chrono Package have been optimised to further improve efficiency and performance, and support the extended breadth of ability of the E-Hybrid models.
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 per cent. Much like a smartphone battery, the battery charges much more slowly when its state of charge reaches approximately 80 per cent or more. This strategy also provides a way of ensuring that full recuperation power is available at all times.
In this way, E-Charge mode is even more efficient than it was previously. In the performance-oriented Sport and Sport Plus modes, the battery is always charged to a minimum level to provide sufficient boost options for sporting responses, 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.
Intelligent charging with the Porsche Mobile Charger Connect
Most drivers charge their vehicles at home so a conventional domestic or industrial electrical socket is sufficient for charging all Porsche plug-in hybrid models. Depending on the vehicle model, a charging power of up to 7.2 kW can be achieved with the Porsche Mobile Charger Connect. Using a Mode 3 charging cable, it is also possible to charge at public charging points. The Mobile Charger Connect offers several intelligent charging functions. A timer ensures that the vehicle is ready by the specific time that the driver plans to set off on their journey. In addition to a pre-defined charging target, specific air conditioning options can be selected. All functions can be controlled via the Porsche Connect App as required.
The new Porsche Cayenne E-Hybrid models are available to order from today, alongside the rest of the range.
Combined WLTP fuel consumption for the Cayenne E-Hybrid models is 76.3 mpg – 91.1 mpg, equivalent to 85 – 71 g/km CO2 Combined.
Combined WLTP fuel consumption for the Cayenne Turbo S E-Hybrid models is 68.9 mpg – 74.3 mpg, equivalent to 92 – 86 g/km CO2 Combined.
