Porsche Boosts Battery, Improves Charging for Cayenne E-Hybrid, Turbo S E-Hybrid

Porsche makes electrical improvements to PHEV Cayennes

  • 2021 PHEV models get larger battery

  • Sport modes tweaked to better use battery back for power and efficiency


Porsche is letting the Cayenne PHEV run a little longer on electrons instead of gas for 2021, thanks to a battery with more capacity as well as drive modes that use the power more efficiently giving it the equivalent of nearly a third more capacity than before. There’s also quicker charging And those changes apply to both of the E-Hybrid models, not just the faster or slower one.

It starts with a gross battery capacity that’s grown from 14.1 kWh to 17.9. That change alone should offer a significant boost, but Porsche has made more changes to the 134 hp and 295 lb-ft electric part of the powertrain.

The internal boost comes from optimised cells, rather than a whole new pack, making the effort easier for the brand’s engineers. The driving modes are also tweaked to further improve efficiency and performance, though Porsche doesn’t detail exactly what the changes are, and hasn’t provided an official range estimate to show what either the 455 hp Porsche Cayenne E-Hybrid or 670 hp Cayenne Turbo S E-Hybrid will do on the open road, but says the changes are equal to a 27 percent capacity increase. For reference, the last E-Hybrid had a 21 km range.

E-Charge, the drive mode that uses the gas engine to charge the battery on the move now targets 80 percent battery, not 100. That improves efficiency because batteries charge much more slowly near the top of the charge, it also ensures that full regen braking is available for improved driving feel. The charging rate in Sport and Sport Plus modes is now higher, topping up the battery more quickly ensuring that power boost is available in those modes.

The 2021 Porsche Cayenne E-Hybrid starts from $93,800 and is available to order now, while the Turbo S E-Hybrid is from $185,600. Both are available in SUV and Coupe body shapes.
