Just the Facts:
  • Porsche releases a shooting brake concept of the Panamera sedan the night before the 2012 Paris Auto Show.
  • The Panamera looks better as a wagon, but the real point of the Panamera Sport Turismo is to preview Porsche's upcoming plug-in hybrid drivetrain.
  • The Panamera and 918 plug-in hybrids go on sale in 2013; the Cayenne plug-in hybrid follows in 2014.

PARIS — Porsche unveiled the Panamera Sport Turismo at the Volkswagen Group Night on the eve of the 2012 Paris Auto Show. It's a wagon concept based off the Panamera sedan, and it previews the company's upcoming plug-in hybrid drivetrain for the production Panamera and Cayenne, which launch in 2013 and 2014, respectively.

Porsche calls the Panamera Sport Turismo "an outlook on a possible Porsche sports car of tomorrow." Stepping out of the cockpit, Matthias Muller, Porsche president and CEO, told the crowd of media, "It's for an active sports car driver who occasionally needs more loading space."

The drivetrain in the Porsche Panamera Sport Turismo concept is very similar to what we've already seen in the Panamera Hybrid and Cayenne Hybrid. It's a parallel hybrid setup where you have an electric motor sandwiched between a gasoline engine and the transmission. The concept uses the now familiar supercharged 3.0-liter V6 rated at 333 hp, and although Porsche hasn't disclosed the transmission, it's likely an eight-speed automatic driving the rear wheels.

The big difference is that the electric motor is now rated for 70 kilowatts (instead of 35kW), and it's receiving power from a much bigger lithium-ion battery pack with capacity of 9.4 kilowatt-hours — a big upgrade from the small, 1.7 kWh nickel-metal hydride pack in the regular Panamera and Cayenne Hybrid. Total system power is 416 hp according to Porsche, but bear in mind that with just one electric motor and a conventional transmission, Porsche's plug-in hybrid still won't be able to blend its gasoline and electric power sources.

What it will be able to do is cover an estimated 30 kilometers (18.6 miles) solely on electric power, with a claimed EV mode top speed of 80.8 mph. Porsche is citing a sub-6-second 0-60-mph time for the Panamera Sport Turismo, which at 194.8 inches long is about an inch shorter than a normal Panamera. It's also 2 inches wider (78.3 inches) and no doubt heavier with its larger battery pack.

There's an "ehybrid" badge on the Porsche Panamera Sport Turismo, and you'll see that again on the plug-in versions of the Panamera, Cayenne and 918 Spyder.

Edmunds says: We'd really like a Panamera wagon, but the bigger deal here is that Porsche is sticking with parallel hybrid system technology, even for its plug-in models, enabling it to keep using the conventional (non-CVT) gearboxes that car guys prefer.
