As if to confirm the world of high-performance cars is moving toward electrification whether we like it or not, Porsche boss Oliver Blume has confirmed the Cayenne SUV will receive a new range-topping model next year called the Turbo S E-Hybrid.

If that moniker sounds familiar, it’s because you remember the news we brought you about the new Panamera flagship bearing the same badging, revealed at the Geneva auto show.

Australian car mag Motoring gleaned the news from Blume in an interview at that very same show, telling the publication the Cayenne would be the second Porsche model ever – after the Panamera – whose top-end variant would use a hybrid powertrain.

And let’s be clear that this is no Prius-like fuel-saver: the combination of twin-turbo V8 and electric motor generates 680 hp and 627 lb-ft of torque, but will also be capable of a promised 50 km of all-electric driving thanks to a plug-in provision for the 14.1-kWh battery pack that will take a full charge in as little and two-and-a-half hours when plugged into an optional fast charger.

Okay, so it’ll be a little bit Prius-like, in that any driver with enough willpower to avoid exploiting that prodigious power for significant lengths of time will enjoy truly frugal fuel consumption: the Panamera fitted with this drivetrain earned a 2.9 L/100 km rating in the New European Driving Cycle (NEDC); expect the bulkier Cayenne to be a bit thirstier.

With the addition of 110 hp compared to the current Cayenne Turbo S, expect this forthcoming Turbo S E-Hybrid to cut a couple tenths off the zero-to-100 km/h acceleration time of 4.1 seconds and provide a top speed approaching 300 km/h.

Watch for the third-generation Cayenne to be unveiled next year, possibly at the 2018 edition of the Geneva auto show that played host to this year’s Panamera reveal.
