Porsche continues to expand hybrid range

ABR Staff Writer Published 02 May 2018

Porsche is launching a new, upgarded Cayenne E-Hybrid plug-in hybrid with more power.

The launch is expected to solidify the company's lineup, while adding significant advancements to its standard Cayenne and the preceding Cayenne S E-Hybrid it replaces.

The advancements include more power, quicker acceleration, higher top speed and increased electric-only range.

Porsche’s Cayenne E-Hybrid uses the 3 liter mono-turbo V6 as the Cayenne, but claims to have increased the total horsepower and torque by adding an electric motor.

The Cayenne has also adopted the same hybrid boost strategy as the 918 Spyder super sports car. Besides adding enhanced performance, Cayenne also comes with Sport Chrono Package, Porsche Active Suspension Management (PASM), and Auxiliary Cabin Conditioning to its list of standard equipment.

Porsche stated that in conjunction with Cayenne E-Hybrid’s launch, it will also introduce several new features to the broader Cayenne model line including massaging seats, a heated windshield, a head-up display, and 22-inch wheels.

This plug-in hybrid’s 3 liter mono-turbo V6 engine produces 335 horsepower and 332 lb/ft of torque with an electric motor that creates 134 horsepower and 295 lb/ft of torque.

This results in a total system output of455 horsepower from 5,250 to 6,400 RPM and 516 lb-ft of torque from 1,000 to 3,750 RPM. The vehicle can accelerate from 0 to 60mph in 4.7 seconds and it has a top track speed of 157mph.

Porsche claims to have completely re-engineered the hybrid powertrain components for the new vehicle, as compared to the Cayenne S E-Hybrid of the previous generation.

The hybrid module has been positioned between the engine and the eight-speed Tiptronic S transmission, includes an electric motor and a separating clutch. This clutch is operated electromechanically for quicker reaction times.

The new Tiptronic S transmission was also developed for the new Cayenne range and claims to offer significantly faster, smoother and more comfortable shifts.

The Cayenne E-Hybrid is fitted with an active hang-on all-wheel drive system with an electronically regulated, map-controlled multiplate clutch. This system claims to have a broad range of torque distribution and offers benefits in driving dynamics, agility, traction control and off-road capabilities.

The electric motor is run by a 14.1 kWh battery pack, which is housed in the rear of the chassis beneath the load floor. This is a liquid-cooled battery consisting of 8 modules with 13 lithium-ion cells each.

Though the size of the battery pack is same as the previous generation vehicle, it has 30% energy density. While running on the battery alone, the vehicle can travel up to 83 miles per hour and up to 44km.

The new Cayenne E-Hybrid is expected to arrive in the US early next year with a base MSRP of $79,900.
