Speaking to Car & Driver at the North American International Auto Show, the engineering boss for the 911 Carrera 4, Targa, and Turbo confirmed “We are developing a pure-electric car like the Mission E, and of course we are discussing plug-in solutions as well for the 911.”
Mössle went on to suggest a plug-in hybrid variant of the 911 is almost a certainty but noted the company still has to deal with a handful of packaging problems. As he explained, Porsche is "fighting hard" to ensure the next-generation model can cope with the size and weight of a lithium-ion battery pack.
Despite the focus on a plug-in hybrid system, Mössle seemed to downplay the possibility of an electric 911. As he hinted, it wouldn't be hard to imagine a two-door coupe based on the Mission E concept but it's "very far in the future" if it happens at all.
Little is known about the next-generation 911 but spy photographers caught a chassis testing mule late last year. The mule didn't reveal much but the extended fender flares suggest the model will have a wider rear axle and some new suspension components.
