With a combined output of 671hp (680PS) from its turbocharged V8 and electric motor, Porsche’s new wild Panamera Turbo S E-Hybrid is the most powerful model in the brand’s range right now, second only to the discontinued 918 Spyder that has 875hp.

Not impressed yet? How about a 0-100km/h run in blazing 3.4 seconds (0-60mph in 3.2 sec) and a top speed of 310km/h (193mph). To put that into perspective, it almost matches the latest 493hp (500PS) 911 GT3 RS that completes the sprint in 3.3 seconds and has the same exact top speed.

True, it lags the pure-electric Tesla Model S P100D’s 0-60mph (96km/h) time of 2.28 seconds, but it puts it right up there with the very best.

Sitting at the top of the Panamera range, the Turbo S E-Hybrid ditches the V6 powertrain of Porsche’s other hybrid, the 456hp (462PS) 4 E-Hybrid, for the regular Turbo S’ 542hp (550PS) 4.0-liter twin-turbo V8 that is paired to a 134hp (136PS) electric motor. Combined, the two deliver a maximum output of 671hp (680PS) and 850Nm (627 lb-ft) of torque from as low as 1400rpm.

And it can do all that while returning an average fuel consumption of 2.9l/100km or 97.4mpg UK (equal to, but not comparable to EPA estimates, 81.1mpg US), with CO2 emissions of just 66 g/km. Porsche’s rating for electric power is 16.2 kW/h/100 km. On top of that, the Turbo S E-Hybrid can be driven on fully electric power for up to 50km or 31 miles.

The electric motor of Porsche’s top plug-in hybrid is supplied with power via a liquid-cooled lithium-ion battery with an energy capacity of 14.1 kWh. The battery can be charged in 6 hours via a regular, 10A house socket, or 2.4 hours from the optional 7.2-kW on-board charger with 32A. Users can start the charging process remotely via the Porsche Communication Management (PCM) or the Porsche Connect app (for smartphones and Apple Watch).

Porsche offers the Turbo S E-Hybrid with two wheelbases, the regular and the 5.9-inches (150mm) longer Executive, which is a tad heavier and slower hitting 60mph in 3.3 sec (vs 3.2 sec).

Standard equipment for both include 21- inch 911 Turbo Design wheels, Ceramic Composite Brakes (PCCB), Porsche Dynamic Chassis Control Sport (PDCC Sport) with Porsche Torque Vectoring Plus (PTV Plus), Power Steering Plus and Sport Chrono Package. Auxiliary air-conditioning, adaptive aerodynamic elements and a three-chamber air suspension including Porsche Active Suspension Management (PASM) are also standard. The long-wheelbase Executive adds rear axle steering, 8-way power rear seats with comfort head rests, and four zone climate control.

In the US, prices will start at $184,400 for the 2018 Panamera Turbo S E-Hybrid, and from $194,800 for the Executive version, both excluding $1,050 delivery, processing and handling fee.

We’ll see Porsche’s strongest Panamera yet at the Geneva Motor Show in early March. You can keep track of the rest of the debuts here.
