Porsche is presenting the Panamera Sport Turismo concept car to show how amazingly intelligent and efficient drive technology might look in the design language of tomorrow. The Sport Turismo unites the next generation hybrid drive with new ideas for an evolutionary, sporty body concept; it combines Porsche performance with comprehensive everyday practicality.
“e-hybrid” stands for plug-in hybrid technology from Porsche
The drive technology of the Panamera Sport Turismo completes the next development step towards the plug-in hybrid, symbolised by the “e-hybrid” badge on the front wings. The car’s new ability to be charged from the electrical power grid has been combined with even higher performance components. The concept vehicle with its 416 hp (306 kW) of peak system power is designed to be driven in pure electric mode up to a speed of 130 km/h and can cover distances of over 30 km. The Sport Turismo also exhibits impressive fuel economy per the NEDC standard; its combined fuel consumption is less than 3.5 litres per 100 km, while CO2 emissions are under 82 g/km.
The drive system of the Panamera Sport Turismo is an advanced development of the parallel full hybrid that Porsche already implements today in the Panamera S Hybrid and Cayenne S Hybrid. The new electric motor produces about 70 kW (95 hp), which is around twice as much as in today’s Porsche hybrid drive, while the three-litre V6 supercharged engine still produces 245 kW (333 hp) here. In their interplay, they accelerate the concept car from zero to 100 km/h in less than six seconds.
Power pack: lithium-ion battery with external charging capability
The electric power pack of the Sport Turismo e-hybrid consists of a lithium-ion battery whose performance is several times that of the nickel-hydride battery currently used in production, although it has practically the same dimensions. Its 9.4 Kilowatt-hours of energy storage capacity and high peak power enable faster acceleration, longer electric driving range and higher speeds when driving without the internal combustion engine.
The default operating mode of the e-hybrid prioritises all-electric driving, but the driver may deactivate this by pressing a special button on the steering wheel. In addition, when the car is being operated in hybrid mode the driver can select the e-charge mode by pressing the steering wheel button to intentionally intensify charging of the high-voltage battery.
This is especially useful when one section of the driving route on a motorway is followed by a section through a city that should be driven in pure electric mode without local emissions. In the e-charge mode, the internal combustion engine charges the battery by load point shifting, while satisfying rational energy management criteria.
As a plug-in hybrid, the fluid-cooled lithium-ion battery is not only charged while driving; it can also be externally charged within 2.5 hours (depending on the power supply) via a charging interface on the vehicle. Porsche systematically thought through all aspects of the concept car’s plug-in system; it utilises a universal charger (AC) that is wall-mounted in a home garage and has a standardised charging plug.
