Like the previous generation Cayenne, Porsche has included an electrified version to bring greater efficiency and performance to its 2019 crossover SUV. It features a completely re-engineered hybrid powertrain compared to its predecessor, the Cayenne S E-Hybrid, using the third new hybrid powertrain from Porsche since just 2017. The 2019 Cayenne E-Hybrid is distinguished from its gasoline counterpart with Acid Green brake calipers and matching outlines around all of the model’s badges, aligning it with other current Porsche plug-in hybrid models.
Porsche’s third-generation Cayenne features new styling cues that lend a more athletic appearance and a lighter weight body courtesy of extensive use of aluminum. It also rides on a lighter weight chassis and incorporates other innovative lightweighting strategies, such a lithium-ion polymer starter battery that brings an additional 22-pound weight reduction on its own.
Power is provided by a 3.0-liter turbo engine offering 335 horsepower and 332 lb-ft torque. The plug-in hybrid powertrain is augmented by a 134 horsepower electric motor boasting 295 lb-ft torque, with the combination delivering 455 total system horsepower and 516 lb-ft torque. The result is exceptional performance featuring 0-60 mph acceleration of 5.7 seconds and a top speed of 157 mph. Power is delivered to the road via an eight-speed Tiptronic S transmission.
Four drive modes allow tailoring the driving experience. E-Power mode allows driving on battery power alone an estimated 20+ miles. An all-new Hybrid Auto mode uses gas and/or electric power to achieve optimum efficiency. E Hold conserves the battery’s current state-of-charge for use at a desired time later in the drive, such as in urban areas. E-Charge mode directs the gas engine to generate more power than needed for driving to charge the battery.
The E-Hybrid is equipped with a liquid-cooled, 14.1 kWh lithium battery with about 30 percent more energy than the previous Cayenne S E-Hybrid. The additional battery power is the result of greater energy density so the size of the battery has not increased. It can be charged from a fully-depleted state with the E-Hybrid’s optional 7.2 kW on-board charger and a 220-volt power source in just over two hours, and with the standard 3.6 kW on-board charger in just under 8 hours.
Porsche’s new InnoDrive is featured in the Cayenne E-Hybrid. The system combines onboard map data and existing traffic sensing systems to look ahead 1.8 miles, allowing it to determine the best balance of gas and electric power for upcoming corners and changes in grade.
