Despite carrying 550 kilograms (96 battery cells each weighing 5.6 kg) worth of Axeon lithium-ion batteries, the 911 goes from 0 to 100 km/h (62 mph) in less than 7 seconds.

Following recent rumours of a fully electric powered Cayman prototype, it has been revealed that the Porsche specialty tuner, Ruf, has in fact developed a fully electric powered 997 prototype. It features a 204hp (150kW) electric motor producing 650 Nm (480 lb-ft) of torque.

Despite carrying 550 kilograms (96 battery cells each weighing 5.6 kg) worth of Axeon lithium-ion batteries, the 911 goes from 0 to 100 km/h (62 mph) in less than 7 seconds. After some mathematical acrobatics, a theoretical top speed of 224 km/h (139mph) is possible given its 1900 kg weight and 160 amps per cell. The 911 EV has a driving range of 250-300 km (155-180 miles) under normal driving conditions.
