Porsche Cars North America announced yesterday that the expanded Porsche Panamera model line is now available in dealer showrooms across the United States.

Porsche expanded the Panamera sports sedan lineup for the 2014 model year with the addition of three new variants: the Panamera S E-Hybrid, the first plug-in hybrid from Porsche; and two luxurious Executive versions based on the Panamera 4S and Panamera Turbo models.

A new 3.0 twin-turbo V6 engine replaces the previous 4.8-liter V8 engine in the Panamera S and Panamera 4S. The new engine is also used in the new Panamera 4S Executive and offers an additional 20 horsepower and 15 pound-feet of additional torque, with an increase of up to 17 percent in fuel economy compared to the V8 engine in the previous model.

Of more interest to readers of this website is the new Panamera S E-Hybrid. Porsche said it has improved the previous Panamera S Hybrid with a more powerful electric motor, and a higher-performance battery that supplies more energy and is able be recharged from home or public charging stations.

The electric drive produces 95 horsepower, double the power of the previous model’s electric motor (47 hp). Electricity is stored in a newly developed lithium-ion battery, which at 9.4 kilowatt-hour has increased capacity over the previous battery (1.7 kWh).

Via the integrated on-board charging components and the standard Porsche Universal Charger (AC), the battery can reach full charge within approximately two and a half hours when connected to a 240V power source.

The Panamera S E-Hybrid is capable of accelerating from a standstill to 60 mph in 5.2 seconds on its way to a top track speed of 167 mph. Well yes, it is and stays true to the Porsche badge!

Porsche declared in July that the hybrid version of the Panamera should account for 10 percent of the global model line’s sales over its lifetime, or around 10,000 units.

The 2014 Panamera S E-Hybrid’s MSRP stands at $99,000.
