At the Paris Motor Show, Porsche presented the Panamera Sport Turismo concept, a plug-in hybrid that offers 416 hp (306 kW) of peak system power. The Panamera Sport Turismo is designed to be driven in pure electric mode up to a speed of 130 km/h (81 mph) and can cover distances of more than 30 km (19 miles). Combined fuel consumption is less than 3.5 liters per 100 km (60 mpg US), combined NEDC, while CO2 emissions are below 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. (Earlier post.) 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 supercharged three-liter V6 engine still produces 245 kW (333 hp) here.
The Panamera Sport Turismo concept accelerates from 0 to 100 km/h in less than six seconds.
The electric power pack of the Sport Turismo e-hybrid consists of a liquid-cooled, 9.4 kWh lithium-ion battery the performance of which is several times that of the nickel-hydride battery currently used in production, although it has practically the same dimensions.
The default operating mode of the e-hybrid prioritizes 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.
In the e-charge mode, the internal combustion engine charges the battery by load point shifting, while satisfying rational energy management criteria.
Instead of classic instruments, a large central TFT color display is positioned in front of the driver; it is used to call up and display any vehicle information as needed— from the tachometer to driving data or navigation. Two monitors, one to the left and one to the right of this display, show images from the “exterior mirror” cameras. Two additional displays in tube form provide information on the hybrid-specific driving states, e.g. pure electric driving, as well as other functions. The power meter in the instrument panel illuminates in Acid Green and shows the combined system power of the two drives.
A press on the left-side touch-sensitive color display starts the e-hybrid. A new type of touch display in the ascending center console incorporates additional controls; this is the control centre for the e-hybrid and all other functions that is implemented in black panel technology. It offers the driver the option of influencing the hybrid drive via smart keys to choose maximum driving fun, maximum performance or maximum efficiency. All driving indicators and control functions are also operated by multi-touch functionality, such as automatic climate control, seat adjustment, lights, reversing camera and the functions of Porsche Communication Management (PCM).
