The 2019 Porsche Cayenne E-Hybrid is Better Than its Predecessor

ATLANTA — Details of the new 2019 Porsche Cayenne E-Hybrid were announced today and Porsche made significant improvements over the standard Cayenne, as well as the preceding Cayenne S E-Hybrid it's replacing.

Among the advantages is more power, quicker acceleration, a faster top speed, and increased range when powered solely by the electric motor. The E-Hybrid uses the same three-liter single-turbo V6 as the Cayenne, except Porsche adds a 14.1 kWh electric motor to significantly increase total horsepower and torque by around 30 percent. With a boost from its electric motor, the Cayenne E-Hybrid produces 455 HP from its standard 3.0-liter turbocharged V6.

The Porsche "E-performance" model adopts the same hybrid boost strategy as the 918 Spyder supercar. By leveraging the instantaneous torque of the electric motor and the power of a turbocharged V6 gasoline engine, Porsche says the Cayenne E-Hybrid has an especially broad power band that improves its acceleration capability.

In addition to enhanced performance, the new 2019 Cayenne E-Hybrid also adds the Sport Chrono Package, Porsche Active Suspension Management (PASM), and Auxiliary Cabin Conditioning to its list of standard equipment.

In conjunction with the launch of the 2019 E-Hybrid, Porsche will also introduce several new features to the broader Cayenne model line. They include massaging seats, a heated windshield, a head-up display (HUD), and for the first time in any Porsche, massive 22-inch wheels.

550HP PHEV Powertrain

The latest Porsche plug-in hybrid includes the third iteration of Porsche's hybrid powertrain since 2017. It combines a three-liter turbocharged V6 engine with 335 horsepower and 332 lb-ft of torque with an electric motor that creates 134 horsepower and 295 lb-ft of torque. The result is a total system output of 455 horsepower from 5,250 to 6,400 RPM and 516 lb-ft of torque from 1,000 to 3,750 RPM.

Acceleration from zero to 60 MPH takes just 4.7 seconds with a top track speed of 157 MPH.

Tiptronic S Transmission and New Hybrid Module

Porsche completely re-engineered the hybrid powertrain componentry in the Cayenne E-Hybrid as compared to the previous generation. The hybrid module, which is mounted 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.

Standard Porsche Traction Management All-Wheel Drive

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 multi-plate 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. Porsche Active Suspension Management (PASM) is included as standard equipment, though customers may upgrade to the same three-chamber air suspension system that is offered in the rest of the Cayenne lineup.

Optional Drive Modes

The Cayenne E-Hybrid offers a wide range of drive modes. The powertrain is able to meet a wide range of driver specific needs—from all-electric motoring to high performance driving.

These include the familiar "Sport" and "Sport Plus" modes from the other Cayenne models equipped with the Sport Chrono Package, while the Cayenne E-Hybrid also adds four hybrid-specific modes: "E-Power", "Hybrid Auto", "E-Hold" and "E-Charge".

The "Hybrid Auto" mode is a completely new development. When this mode is selected, the Cayenne changes and combines the drive sources automatically for ultimate efficiency. In "E-Charge" mode, the gasoline engine generates more power than is needed to move the car. The excess energy is channeled into the battery for later use.

Porsche vehicles are all about the driving experience, and the E-Hybrid Cayenne continues the traditional. The highest level of drive performance is made available in the "Sport" and "Sport Plus" modes. The V6 engine is active continuously in these modes. In "Sport" mode, the battery charge is always maintained at a minimum level to ensure that sufficient boost reserve capacity is available when needed. "Sport Plus" mode is all about maximum performance. In addition, the battery is charged as quickly as possible to ensure maximum performance.

Battery Power

Power is stored in a 14.1 kWh battery pack housed in the rear of the chassis beneath the floor. While running on electricity alone, the Cayenne E-Hybrid can travel up to 83 miles per hour and up to 44 kilometers. EPA fuel economy figures and electric range are unannounced at this time.

Battery capacity of the Cayenne E-Hybrid increases by roughly 30 percent to 14.1 kWh when compared to the preceding model, which was equipped with a smaller, 10.8 kWh electric motor.

The liquid-cooled battery consists of eight modules with 13 prismatic lithium ion cells each, which reduces weight and costs. The packaging size of the prismatic battery pack is the same as the battery used in the previous Cayenne S E-Hybrid, while offering improved energy density.

Using a 230-volt, 32 amp connection and the optional 7.2 kW onboard charger, it is possible to recharge the E-Hybrid's 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.

Remote Access with the Porsche Connect App

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 EV charging stations and set them as a navigation destination.

In addition, Porsche is offering a head-up display (HUD) for the first time. The full-color projection is customizable, height-adjustable, and it puts key information in the driver's line of sight, including driving speed, engine speed, driving mode, and navigation information.

Models equipped with the Sport Chrono package – such as the Cayenne E-Hybrid – can see information relevant to the added performance capability including lap times and cornering g forces. Models equipped with the Off Road package are able to display similarly relevant information including hillside gradients, steer angle, a compass, and hill descent control speeds.

Selecting Gears Automatically based on Map Data

Starting with the 2019 Cayenne E-Hybrid, Porsche's unique InnoDrive system will also be available. Innodrive is a step beyond adaptive cruise control and combines already existent traffic sensing systems with onboard map data.

With Innodrive, the vehicle that can "look" at the road 1.8 miles ahead to select gearing and that can compute when best to coast or the best balance between the gasoline and electric portions of the powertrain based on upcoming corners and changes in grade, such as when approaching hilly terrain. The system is also capable of recognizing speed limits and adjusting vehicle velocity in cases where temporary speed restrictions are in place.

The new Cayenne E-Hybrid is expected to begin arriving at U.S. dealers in early 2019 with a base MSRP of $79,900.
