Porsche will unveil a hybrid version of the Panamera next month at the Geneva auto show.
The Panamera S hybrid uses the same driveline offered in the Cayenne hybrid and its sister model, the Volkswagen Touareg hybrid. The system is mated to a 333-hp supercharged 3.0-liter V-6 gasoline engine.
European sales of the Panamera S Hybrid start in June, priced at 106,185 euros in Germany, 10,000 euros more than the standard Panamera S. North American sales begin later this year.
The Panamera S hybrid is capable of running on either electric propulsion alone, for short distances, or a combination of gasoline-and-electric power. In pure electric mode, Porsche says the sedan has a range of up to 2km (1.2 miles) at speeds up to 85kph (53 mph).
Electric energy created during braking and coasting is the only source of charge for the battery, although Porsche is believed to be working on a plug-in application that would bring a longer range and the likelihood of a more powerful lithium-ion battery.
