Porsche dealers will get their first plug-in hybrid to sell by the end of this year.
The plug-in hybrid is part of the restyled -- and bigger -- Panamera family of four-door sedans that will begin arriving at U.S. dealerships in late 2013 as 2014 models. The plug-in is on schedule for a December sales launch, a Porsche spokesman said.
The plug-in, dubbed the Panamera S E-Hybrid, will be joined by two new extended-wheelbase variants. The lineup also adds a new twin-turbo V-6 engine for the Panamera S and 4S models that is more powerful than the former base V-8.
Porsche will debut the new Panamera models at the Shanghai auto show this month.
The plug-in replaces the current Panamera hybrid.
As part of the plug-in Panamera's rollout, every U.S. dealer will get several chargers to install at their stores, the spokesman said. The Panamera S E-Hybrid also comes with its own portable charger that can connect to 110- or 220-volt outlets.
The coming model has an electric motor that produces 95 hp, Porsche says, double the 47 hp of the electric motor in the current hybrid. The hybrid powertrain has a combined output of 416 hp with a top speed of 167 mph. The car can accelerate from 0 to 60 mph in 5.2 seconds, a half-second faster than the current hybrid.
Pricing for the plug-in will start at $99,975, including shipping, nearly $3,000 more than the base price for the current hybrid.
The current hybrid accounts for 5 to 10 percent of the Panamera's monthly U.S. sales, a spokesman said. Porsche sold 7,614 Panameras in the United States in 2012.
Porsche expects the new Panamera hybrid to get better fuel economy than the current car; it did not provide an estimate or EPA rating. The current Panamera hybrid is rated at 22 mpg in city driving, 30 mpg on the highway and 25 mpg combined.
Porsche says the new hybrid has a range of more than 20 miles and a top speed of 84 mph on electric power. The battery pack can be fully recharged in about 2.5 hours from a 240-volt power source.
The electric motor provides boost under hard acceleration and powers the car during coasting when the V-6 shuts down.
The extended-wheelbase version, dubbed the Panamera Executive, gets an additional 5.9 inches, stretching it to 120.9 inches, with the extra room going to back-seat passengers. Executive models arrive in the United States in 2014.
Styling changes to all Panameras include a new front fascia with larger air intakes. The restyled rear looks wider with larger rear glass and restyled fascia. The Panamera's new styling and the plug-in hybrid powertrain were previewed last fall at the Paris auto show on the Panamera Sport Turismo concept.
