2021 Porsche Cayenne E-Hybrid and Turbo S E-Hybrid gain larger battery pack

Porsche’s range of 2021 Cayenne E-Hybrid models (the PHEVs) are getting higher capacity battery packs in the new year. All the E-Hybrid variants in 2020 made do with a 14.1 kWh pack, but the 2021 models will have a 17.9 kWh battery pack. The increase comes thanks to optimized cells that leads to greater energy density. It's the same battery pack improvement that we saw with the updated 2021 Panamera E-Hybrid range.

Cayennes with this new pack for 2021 include the E-Hybrid, E-Hybrid Coupe, Turbo S E-Hybrid and the Turbo S E-Hybrid Coupe. It’s an approximately 27% increase in size, so we expect a similar increase in range for these models. The non-Turbo cars were rated by the EPA for 14 miles of all electric driving. With this increase, you’ll likely be looking at 17-18 miles of range. The more powerful and heavier Turbo S E-Hybrid was rated for 12 miles, so expect it to be about 15 miles for 2021. These baby step increases in range are not game changers, but they are welcome improvements to otherwise low electric range plug-in hybrids.
