2018 Porsche Panamera Turbo S E-Hybrid – Video
This time around, Porsche is throwing its hybrid expertise into the mix. The meat of the advanced powertrain is the same 4.0-liter twin-turbo V-8 from the Panamera Turbo, churning out 542 hp and 567 lb-ft of torque. Sandwiched between the engine and eight-speed PDK dual-clutch automatic is an electric motor that adds 134 and 295 lb-ft to the equation. Porsche rates the Panamera Turbo S E-Hybrid’s total system output at 671 hp and 626 lb-ft. There’s lots of power and also lots of weight. The large sedan also has to contend with all-wheel-drive hardware, and a 14.1-KWh battery pack in the plug-in hybrid sedan tips the scales at an estimated 5,093 pounds, about 600 more than the Panamera Turbo. That said, the Turbo S E-Hybrid has a slight power-to-weight ratio advantage at 7.5 hp per pound versus 8.2.
Acceleration is immense and instantaneous, much like previous high-performance plug-in hybrids we’ve driven including Porsche’s own 918 Spyder. The automaker claims a 0-60-mph time of 3.2 seconds, but we wouldn’t be surprised if it dips below 3 seconds once we test it. Top speed is rated just under the 200-mph mark at 192 mph.
