Porsche Panamera S Hybrid Video: Luxury Goes Green

A week after teasing the announcement of a new production hybrid model at the Geneva Motor Show, Porsche has revealed the Panamera S Hybrid.  Everyone knew this hybrid GT was coming; Porsche told us as much when the Panamera debuted in 2009.

In fact, there really are no surprises about the hybrid-electric Panamera. The powertrain is basically the same found in the battery-assisted Cayenne and Volkswagen Touareg. That means primary propulsion is provided by the sweet supercharged and direct-injected 3.0-liter V6 created by the Volkswagen Group. In the hybrid applications it generates 333 horsepower and a stout 325 pound-feet of torque.

Additional motivation is provided by a disk-shaped 46 hp electric motor that takes the place of the torque converter for the eight-speed ZF automatic transmission.  A clutch on either side of the motor allows either blended gas-electric drive, pure electric drive or simple neutral coasting.  Electrical energy generated by the engine turning the motor or regenerative braking is stored in a nickel metal hydride battery pack  that sits under the trunk. Given the price of the Panamera, its odd that Porsche has opted for the older battery technology rather than the lithium ion pack that Audi is using for its upcoming Q5 hybrid. With Porsche’s continuous improvement philosophy, the battery will probably be updated within a year or two.

The motor-transmission configuration means that the motor is spinning at lower speeds  than the motors in integrated power-split hybrids like those from Toyota, Ford and General Motors. That means it can cruise in pure electric mode at speeds up to 53 mph. Oddly, that’s slower than the 80+ mph speeds possible with the Cayenne.

Aside from the powertrain configuration, the rest of the functionality is pretty much what you would expect from any strong hybrid system. That means automatic start-stop, electric boost and regenerative braking.  In addition to the drive system, Panamera hybrid buyers can also select new specially developed Michelin low rolling resistance tires.

On the European drive cycle, that all adds up to a combined average of 34.6 miles per U.S gallon, a mighty impressive number for such a large car that sprints to 60 mph in just 6.0 seconds.  Stick with real tires, and you’ll do a bit worse at only 33.1 mpg.  Results achieved on the EU drive cycle tend to be a bit more optimistic than EPA’s numbers so real world results will probably be closer to the mid-to-upper 20s.

The Panamera S Hybrid goes on sale in Europe in June of this year and comes to America in the fall with a base price of “just” $95,000. That makes it a bargain compared the Lexus LS600h, and the Porsche will actually be entertaining to drive, unlike any LS. Even so, 100G of Porsche money should go to something proper, like the 4S Turbo, but hey, it’s your money.
