Porsche Cayenne E-Hybrid range, MPG, CO2 & charging

Faster charging with a Type 2 charging cable cost extra, but otherwise the Porsche Cayenne E-Hybrid is competitive

The Porsche Cayenne E-Hybrid has an official electric range of up to 22 miles, which is close to what you should see in normal everyday use. CO2 emissions range from 89g/km for the E-Hybrid to 122g/km for the forthcoming (more powerful) Turbo S E Hybrid version.

That's a bit higher than is ideal for the best possible company-car tax costs. With the battery depleted and the V6 petrol engine in use, you’ll see around 30mpg fuel economy.

Charging times are similar to those of most rivals, and with the normal three-pin domestic plug cable provided, you can fully charge the Cayenne E-Hybrid in just over six hours, making for easy overnight charging.

Porsche Cayenne e-Hybrid range

The E-Hybrid has an official pure electric range of 22 miles, which is close to what you should get in normal varied use. More motorway miles (the E-Hybrid will do 84mph in pure electric mode) and/or cold conditions will see that dip towards 15 miles, although the figure can rise to 25 miles around town.

It’s enough to cater for most people’s commutes, and there are also functions to hold the battery charge and even top up the battery using the turbocharged petrol engine. With the battery is depleted and relying solely on the smooth V6, we managed to get around 30mpg.

Charging time

The Cayenne comes as standard with a maximum charging speed of 3.6kW, which equates to around four hours for a full charge when plugged into a 3.6kW charger. Pay around £500 and Porsche will increase the maximum charging speed to 7.2kW, dropping the fastest full charge time to two hours.

However, to take advantage of those faster charging times, you’ll need a Type 2 cable that allows you to plug into AC fast chargers. That costs another £300 or so, which seems cheeky on a car of this price.

If you decide that you don’t need the faster charging, then simply plugging the Cayenne into a normal socket in your house should still give you a full charge in six hours. That’s roughly on a par with rivals like the Volvo XC90 T8 and Range Rover Sport PHEV.

Battery warranty

The Cayenne E-Hybrid’s battery is covered under warranty for eight years or 160,000km (just under 100,000 miles). However that doesn’t include a guarantee of replacement if the battery’s performance drops below a certain level. Porsche isn’t an exception here, though: currently no plug-in hybrid is offered with this level of battery cover.
