Sept. 7 (UPI) -- German carmaker Porsche unveiled a hybrid variant of its flagship 911 Turbo S, making it the most powerful production model in the sports car's six-decade history.

The sports car was unveiled Sunday at the Internationale Automobil-Ausstellung Mobility show in Munich, Porsche announced in a news release.

Frank Moser, Porsche's vice president of the 911 and 718 model lines, called the hybrid the "most complete and versatile form" of the flagship model to date.

The car uses a newly developed 3.6-liter flat-six engine paired with a 400-volt electric system that delivers an instant boost of power, Porsche said.
