Porsche has introduced a new 2019 Cayenne E-Hybrid model which makes significant advancements over the previous S E-Hybrid it will replace. The new model has more power, acceleration, and electric range. The crossover uses the same V6 engine as the standard gasoline option, but adds electric components to the mix for a plug-in hybrid setup.
The 2019 Cayenne E-Hybrid’s plug-in powertrain is similar to that found in the 918 Spyder sports car, comprising the third new powertrain from Porsche in the past year. The 3.0-liter mono-turbo V6 outputs 335 horsepower and 332 pound-feet of torque and combines with an electric motor that adds 134 hp and 295 lb-ft. The total system output is 455 horsepower and 516 lb-ft of torque starting at just 1,000 rpm.
Porsche says that this results in acceleration to 60 mph in just 4.7 seconds (nearly a full second faster than the outgoing Cayenne S E-Hybrid) and a quarter mile time of 13.3 seconds. Top speed is 157 mph.
Porsche completely re-engineered the hybrid powertrain components in the Cayenne E-Hybrid as compared to the Cayenne S E-Hybrid of the previous generation. The hybrid module, which is positioned between the engine and eight-speed Tiptronic S transmission, consists of an electric motor and a separating clutch. In contrast to the previous electro-hydraulic system with a spindle actuator, the separating clutch is operated electromechanically for quicker reaction times.
The new Tiptronic S transmission, which was developed for the third-generation Cayenne range, offers significantly faster, smoother, and more comfortable shifts. This also leads to a reduced interruption of tractive force while changing gears. As with other Cayenne models, the top track speed is reached in sixth gear, leaving the remaining two gears intentionally long for efficient cruising.
With standard Porsche Traction Management (PTM), the Cayenne E-Hybrid has an active hang-on all-wheel drive system with an electronically regulated, map-controlled multiplate clutch. With its broad range of torque distribution, the system offers clear benefits in terms of driving dynamics, agility, traction control and off-road capabilities.
Power is stored in a 14.1 kWh battery pack housed in the rear of the chassis beneath the load floor. While running on electricity alone, the Cayenne E-Hybrid can travel up to 83 mph (134 km/h) and up to 44 kilometers (27 miles) (NEDC). EPA fuel economy figures and electric range are unannounced at this time.
Battery capacity of the Cayenne E-Hybrid increases by roughly 30% to 14.1 kWh when compared to the preceding model. The liquid-cooled battery consists of eight modules with 13 prismatic lithium ion cells each. The packaging size of this battery pack is the same as the battery used in the previous Cayenne S E-Hybrid, but it has improved energy density.
Using a 230-volt, 32 amp connection and the optional 7.2 kW onboard charger, it is possible to recharge a fully depleted battery in 2.3 hours. Using a 230-volt connection with 10 amps and the standard 3.6 kW on-board charger, replenishing a fully depleted battery requires 7.8 hours. In both cases, the recharging process is quicker with the new Cayenne E-Hybrid than in prior models.
The charging process is controllable either via Porsche Communication Management (PCM) or remotely when using the Porsche Connect app. With an enabled smartphone, owners gain remote access to climate controls, and charge monitoring. All of these features are included as standard equipment and function even when the ignition switch is turned off. Porsche Connect can also be used to find and filter charging stations and set them as a navigation destination.
The 2019 Porsche Cayenne E-Hybrid has entered the German market and is expected to proliferate through Europe, starting this month, and will arrive in the United States in early 2019. Base MSRP will be $79,900 plus delivery.
