Porsche's hybrid to hit showrooms in 3 years

WEISSACH, Germany — Porsche AG's first hybrid vehicle will be ready within three years, the head of the luxury automaker's new hybrid program announced Thursday, saying it showed progress by a company derided by some environmental groups as a climate destroyer.

Leaders of Germany's auto industry have rejected criticisms that they lack the initiative to build more environmentally friendly cars, saying this week that they were working on new, fuel-efficient models.

Porsche's Cayenne hybrid is being developed in part with Volkswagen AG and Audi AG, and when complete is expected to reduce the sport utility vehicle's fuel consumption by almost one-third.

The four-door SUV is expected to be on the market by the end of the decade, the Stuttgart-based automaker said, a major move for the company in an increasingly carbon-conscious world.

Michael H. Leiters, the head of the hybrid program, said the move toward a hybrid is part of a wider effort to help its customers shake off the image of being gas-guzzling planet haters.

"If you drive a Porsche in the neighborhood and everyone is ... saying you are environmentally unfriendly, that is not good for us," he said, adding that developing the hybrid is "for us, a good solution."

Criticism about Porsche's sports cars, which include the Boxster and 911, can be severe.

Greenpeace protested the company's production at its plant in Zuffenhausen on Thursday, accusing it of building cars the group called "climate pigs."

Porsche noted in response that in Germany, less than 12 percent of all exhaust emissions come from passenger cars, with Porsche's share of that being less than 1/10th of 1 percent.

The hybrid Cayenne prototype emits just 240 grams of carbon dioxide per kilometer, compared with 310 grams from a normal gas-powered Cayenne.

Porsche won't say how much the hybrid version will retail for, but has said the United States is the key market for the car.

The hybrid will use about 8.9 liters (2.4 gallons) of gas per 100 kilometers (62 miles), compared with 12.9 liters (3.4 gallons) for a conventional model. So far, in testing, it gets about 24.4 miles per gallon compared with 17.9 miles per gallon for a conventional Cayenne.
