Porsche’s electric-car offensive won’t include an all-electric 911, despite the manufacturer expecting Fully Electric and electrified models to account for 25 percent of its total sales by 2025.

The German carmaker has already confirmed it’s working on a plug-in hybrid 911, which will sit on top of the range as the most powerful 911 of all time, but it will never give its core sports car a fully electric powertrain.
