A Porsche with a hybrid system!And a Porsche with four seats!The Panamera has already dished out its share of surprises for sports car fans. Now, for the second generation, the Panamera 4 plug-in E-hybrid has been joined by anotherwith 500 kilowatts of system power. But for today, we’ll stick with the less powerful plug-in-hybrid. Its electric motor and 243-kilowatt V6 gasoline engine add up to a total system power of 340 kilowatts. Fuel consumption is rated at just 2. 5 liters per 100 kilometers, but only as longas the driver resists the temptation to really step on it. Our tester Reinhold Deisenhofer points out that, since the Panamera E-hybrid weighs 2. 2 tons,it takes some power to push that weight from zero to 100 kilometers per hour in justfive seconds, but the system has a good 700 newtonmeters of torque. The Normal drive mode recharges the battery on the go, and then there are the Sport andSportplus modes. In all three, the overboost function temporarily steps up the boost pressure for the pick-uptypical of Porsche. As in most hybrids, the display can show the energy flow at any time. A Porsche is a Porsche is a Porsche. The design has spoken the same easily recognizeable language for decades, and the Panamera isno exception. The E-hybrid differs from the 4-seater’s gasoline-powered version only in small details – such as thegreen-rimmed badging and the green brake calipers. The Panamera 4 E-hybrid is 5 meters and 5 centimeters long. The longer executive body style is available on request. Tucked under the front hood is the V6 with 2. 9 liters capacity. Reinhold Deisenhofer realizes that, with a Porsche, sound is always a factor. In all-electric drive, the E-hybrid glides over the asphalt on its air suspension inalmost total silence. But if you really bring out the performance, it sounds just like the Porsches we’ve always known. The Panamera E-hybrid pounces from 80 to 120 kilometers per hour in just 3. 1 seconds- only a fraction of a second slower than other Panamera variants – because of the fewhundred extra kilos the battery adds. Reinhold explains that it takes about 6 hours to fully recharge the e-hybrid’sbattery from a European 220-volt household outlet. A quick-charge station for an extra four and a half thousand euros will cut two hours offthat time. The Panamera E-hybrid’s competitors are the Mercedes Benz S500 and the BMW 7 seriesr as plug-in-hybrids,but in the family of Panameras, the Porsche e-Hybrid is actually the lowest priced of them all.
