Porsche Cayenne S E-Hybrid Platinum Edition
The 2017 Porsche Cayenne S E-Hybrid Platinum Edition plug-in hybrid thumped up onto Car and Driver’s California scales and punished them to the tune of 5373 pounds. That’s 54 pounds less than we recorded for the slightly less lavish non–Platinum Edition version during testing in Michigan. Hey, California gravity is groovier than Michigan gravity. Or maybe it was the nearly $10,000 in extra options on the Michigan car that added mass.
The vehicle with the longest name in Porsche’s lineup is plug-in hybrid gasoline-electric crossover. It is technically a second-generation hybrid version, surpassing its predecessor with new plug-in capabilities that allow it to recharge using a standard household 110-volt outlet (in about 11 hours) or a dedicated 240-volt outlet (in less than three hours).
Opening the hood only reveals a portion of the powertrain, which literally make a sandwich from a supercharged 3.0-liter V6 (rated at 333 horsepower), an electric motor (rated at 95 horsepower), and a slick-shifting 8-speed automatic transmission. The brilliant engine/motor/transmission configuration allows either the electric motor, combustion engine, or both to drive the Cayenne down the road (a sophisticated permanent all-wheel drive system decides which of the wheels get the most power).
Porsche S E-Performance. Direction: Future.
Porsche S E-Performance provides answers. Right here and now. Because we need to reduce fuel consumption and CO2 emissions worldwide. As a Sports Car manufacturer, we believe that we should begin where we can really make a difference: in the garage and in the everyday lives of our drivers. With a carefully planned concept. So let’s get going. Into the future.
Of course, the standard Cayenne S E-Hybrid ($78,700) will do these things equally as well as the Platinum Edition ($81,600) because they are mechanically identical. However, differentiating the two (and easily substantiating the $2,900 difference in price) is the bundled equipment that is standard on the premium trim. In a nutshell, the Cayenne S E-Hybrid Platinum Edition arrives with everything the Cayenne S E-Hybrid does, but then adds more than a dozen other features.
The electrical substance of the E-Hybrid system is conceptually a carryover from the now superseded Panamera E-Hybrid, including its Audi-sourced 333-hp supercharged 3.0-liter V-6. It’s an evolutionary half-leap forward from the first Cayenne hybrid system as well. The electric motor/generator produces 95 horsepower and 229 lb-ft of torque (41 horses and 66 lb-ft less than the motor in the 2018 Panamera Turbo S E-Hybrid). It’s fed by a 10.8-kWh lithium-ion battery pack, mounted under the cargo floor, that can be replenished from an optional onboard 7.2-kW charger using a standard SAE J1772 connector or from Porsche’s own charging system that mounts on an owner’s garage wall .
