The Porsche Taycan just completed 2,128 miles in 24 hours on the Nardo test ring

Porsche says a pre-production Taycan managed to cover 2,128.1 miles in a single 24-hour period on the Nardo high-speed test track. Its only stops were for charging and driver changes — six factory test drivers shared the duties over the 24-hour test. How was Porsche able to get enough charge into the battery pack fast enough to cover all those miles?
