As part of the 2013 Panamera facelift, Porsche announced the introduction of a plug-in hybrid model, the Panamera S E-Hybrid. The plug-in version was unveiled at the April 2013 Shanghai Auto Show. The S E-Hybrid is powered by a 71 kW (97 PS; 95 bhp) electric motor, with a total system power of 310 kW (421 PS; 416 bhp). Top speed is 84 mph (135 km/h) in all-electric mode, and its time from 100 km/h (62 mph) is 5. 2 seconds. The plug-in electric hybrid will have a 9. 4 kWh lithium-ion battery pack capable of delivering a range of more than 32 km (20 mi) under the New European Driving Cycle (NEDC) standard. The battery can be fully charged in approximately 2½ hours from a 240V power source. The Panamera plug-in hybrid reduces fuel consumption to 3. 1 L/100 km (91 mpg‑imp; 76 mpg‑US), down from 7. 11 L/100 km (39. 7 mpg‑imp; 33. 1 mpg‑US) for the current Panamera hybrid, which translates to CO2 emissions of 71 g/km, down from 167g/km for the current hybrid.
