Porsche will have an electric car on sale in five to ten years, according to company boss Michael Macht.
Speaking to German magazine Welt am Sonntag, Macht said that Porsche is working "intensively" on an electrically powered sports car.
However, he added that it would take some time until a marketable model could be introduced "with a reasonable reach, achieving the same handling characteristics of a gasoline engine."
He added: "I could imagine that we will drive the first vehicles in as soon as five to ten years."
Macht also predicted that Porsche would near double its annual sales to 150,000 cars a year in the mid to long-term, so long as new models are added to the range.
"If the world economy picks up again, we can well imagine unit sales of 150,000 Porsche cars per year," said Macht.
"But we won't achieve this with the four models that are existing today. Otherwise, we would have to significantly increase the number of cars of the current models. And then we would not be exclusive anymore. Therefore we have to think about new vehicles."
These are believed to be a car based on the VW BlueSport roadster concept, an Audi Q5-based car close to the Roxster concept and a Panamera coupe.
