  • Porsche is putting larger-capacity battery packs in the 2021 Cayenne E-Hybrid lineup.

  • The new batteries have a capacity of 17.9 kWh vs the current capacity of 14.1 kWh.

  • While a range increase is expected, without a proper EPA test, it's tough to determine how much this change will affect MPG and EV-only range.

Porsche seems to be on a battery-replacing stint these days. After upgrading the capacities in the upcoming Panamera E-Hybrid, the automaker announced today that the Cayenne E-Hybrid will go from 14.1 kWh to 17.9 kWh of capacity.

While a range increase is expected with the larger battery capacity, we won't know exactly how much until the EPA publishes its official test numbers. What we do know is that the powertrain in the plug-in 2021 Cayenne hybrid is unchanged from the 2020 Cayenne E-Hybrid, sporting a turbocharged 3.0 liter V-6, while the Turbo S E-Hybrid is still equipped with a twin-turbo 4.0 liter V-8. The vehicles' power output is 455 horsepower and 670 horsepower, respectively.

Porsche also announced that E-Hybrid Cayennes outfitted with the Sport Chrono package have a new calibration strategy that sets the state-of-charge goal to 80 percent instead of 100 percent when the driver has the gasoline engine recharging the battery. On a practical note, this type of charging is recommended for EVs and hybrids to increase the life of the battery pack and is a more efficient use of the gas engine.
