Porsche has revealed new technical details of its upcoming Cayenne Electric, featuring a 113 kWh function-integrated battery, dual-sided cooling, and 400 kW fast charging that set a new benchmark for high-performance electric SUVs.
Built on an enhanced version of Porsche’s Premium Platform Electric (PPE), the Cayenne Electric adopts an 800-volt architecture that improves energy efficiency and significantly reduces charging times. In independent U.S. highway tests, near-production prototypes achieved more than 350 miles (563 km) of range, with Porsche targeting an official WLTP figure exceeding 600 km.

At the heart of the vehicle is a 113 kWh lithium-ion battery that functions as a structural element, enhancing rigidity and lowering the center of gravity. The battery incorporates 192 large-format pouch cells featuring nickel-manganese-cobalt-aluminum (NMCA) cathodes and graphite-silicon anodes, offering 7% higher energy density than the latest Taycan.
The Cayenne Electric also introduces Porsche’s first dual-sided cooling system, maintaining optimal battery temperatures for consistent performance. Its predictive thermal management system uses real-time navigation and traffic data to regulate cooling and heating circuits, improving both efficiency and charging speed.

With its 800-volt system, the SUV supports up to 400 kW DC charging—enabling a 10–80% charge in under 16 minutes and adding 300 km of range in just 10 minutes. A high-voltage switch allows 200 kW charging on 400-volt networks without external boosters. Starting in 2026, Porsche will also offer 11 kW wireless charging through an inductive floor-mounted plate with up to 90% efficiency.
“With the Cayenne Electric, we are taking e-performance to a new level,” said Dr. Michael Steiner, Deputy Chairman of the Executive Board and Member of the Executive Board for Research and Development. “Our innovative high-voltage system combines maximum efficiency with the driving dynamics typical of Porsche.”
