Porsche will debut the latest member of the Panamera family next week in Geneva with a car that will become the company’s first-ever hybrid-powered flagship model.

The Stuttgart sports car maker is quick to point out that though this hybrid promises lower fuel consumption than the Panamera Turbo, that’s really not the point.

Key to the Turbo S E-Hybrid is an electric motor that joins forces with the Turbo model’s twin-turbo V8 to generate a total of 680 hp and 627 lb-ft of torque, representing increases of 130 hp and 60 lb-ft.

And that, says Porsche, is enough for a 3.4-second sprint from zero to 100 km/h and a top speed of 310 km/h, both figures besting the Panamera Turbo, albeit nominally.

The standard Panamera E-Hybrid model lends its plug-in hybrid charging system to the cause to provide about 50 km of all-electric driving range, and an eight-speed dual-clutch transmission sends all that power to the car’s four wheels.

Storing and delivering electricity is a 14.1-kWh battery that can be charged in six hours via a standard wall outlet, or as quickly as 2.4 hours with an optional fast charger.

With a fully-charged battery and a driver who can resist the urge to exploit 680 hp, Porsche says the Panamera Turbo S E-Hybrid is good for a 2.9 L/100 km fuel consumption rating, according to the New European Driving Cycle (NEDC) measurement.

More to the point of what this car is about, however, it’ll come in regular and long-wheelbase (Executive) versions, and will come standard with a carbon-ceramic brake system that’s a very pricey option in other Panamera variants.

Other standard stuff includes dynamic chassis control sport, torque vectoring plus, 21-inch wheels modeled after those on the 911 Turbo, air ride with active suspension management and, in long-wheelbase models, rear-axle steering.

The Porsche Panamera Turbo S E-Hybrid goes on sale in Europe this summer. It will reach Canadian showrooms closer to the end of 2017, when it will be priced starting at $209,800 in standard trim and $221,700 in Executive guise.
