At the upcoming 2016 Paris Motor Show next month, Porsche is set to unveil the fourth model in the Panamera line called the Panamera 4 E-Hybrid.
The new Panamera 4 E-Hybrid features a hybrid strategy never before seen in this segment – a strategy based on the 918 Spyder. The 887 hp 918 Spyder is the fastest series-produced vehicle ever to circumnavigate the Nürburgring Nordschleife. Its record lap time of 6:57 minutes can in part be attributed to the additional power provided by two electric motors.
As with the 918 Spyder, the power of the Panamera electric motor – 136 hp and 400 Nm torque – is made available as soon as the driver touches the accelerator pedal. The plug-in hybrid always starts in purely electric mode and drives without generating any local emissions within a range of 50 kilometres and a maximum speed of 140 km/h.
Like with the 918 Spyder, the electric motor is available to deliver additional power at all times. This, together with the performance characteristics of the new 2.9-litre V6 biturbo engine (330 hp/450 Nm), generates a total of 462hp and 700Nm of torque. As on the other second-generation Panamera models, a new Porsche 8-speed Doppelkupplung (PDK) transmission is used to transmit the power to the all-wheel drive. This transmission replaces the 8-speed automatic torque converter transmission on the predecessor model.
As a result, the four-door hybrid sports car breaks the 100 km/h barrier in just 4.6 seconds before reaching a top speed of 278km/h.
In terms of fuel economy, the hybrid sports car delivers fuel consumption figures of 2.5 l/100 km in the New European Driving Cycle (NEDC) for plug-in hybrid models. That corresponds to CO2 emissions of 56 g/km.
The electric motor is supplied with power via a liquid-cooled lithium-ion battery. And despite the fact that the energy content of the battery (which is integrated under the luggage compartment floor) has been increased from 9.4 to 14.1 kWh, its weight has remained the same. The high-voltage battery takes just 5.8 hours to fully charge via a 230-V, 10-A connection. If the driver chooses to use the optional 7.2 kW on-board charger and a 230-V, 32-A connection instead of the standard 3.6-kW charger on the Panamera, the battery fully charges in just 3.6 hours. The charging process can also be started using a timer via Porsche Communication Management (PCM) or the Porsche Car Connect app (for smartphones and Apple Watch). Moreover, the Panamera 4 E-Hybrid is fitted as standard with auxiliary air conditioning to cool or heat the passenger compartment during charging.
One highlight of the 2nd-generation Panamera is the newly designed display and control concept in the form of the standard Porsche Advanced Cockpit with touch-sensitive panels and individually configurable displays. Two 7-inch screens either side of the analogue rev counter form the interactive cockpit, and, in contrast to the other versions in the model line, the Panamera 4 E-Hybrid features a power meter tailored to hybrid operation. The intuitive operating principle of the hybrid-specific displays is similar to that used in the Porsche 918 Spyder super sportscar. The power meter provides data such as the amount of electrical energy currently being used as well as that recovered through recuperation.
A 12.3-inch touchscreen functions as a central PCM control and display unit. The driver can access various items of hybrid-specific information both here on the dash and in the instrument cluster. The boost assistant and hybrid assistant are both practical and informative. The boost assistant display shows the energy available for boosting, while the hybrid assistant provides various visual signals for regulating the electrical drive power.
The Sport Chrono Package including the mode switch integrated into the steering wheel forms part of the standard equipment on the Panamera 4 E-Hybrid. The mode switch and Porsche Communication Management are used to activate the various driving modes. These modes include the familiar “Sport” and “Sport Plus” modes from the other Panamera models equipped with the Sport Chrono Package. The hybrid-specific modes are “E-Power”, “Hybrid Auto”, “E-Hold” and “E-Charge”.
The Panamera 4 E-Hybrid always starts in the purely electric “E-Power” mode. The “Hybrid Auto” mode is a completely new development. When this mode is selected, the Panamera changes and combines the drive sources automatically for ultimate efficiency.
The “E-Hold” mode allows drivers to consciously conserve the current state of charge to enable them to switch to electric and therefore zero-emissions mode in an environmental zone at their destination, for example. In “E-Charge” mode, the battery is charged by the V6 engine; to achieve this, the petrol engine generates a higher level of power than is actually needed for driving.
The highest level of drive performance is made available in the “Sport” and “Sport Plus” modes. The V6 biturbo engine is active continuously in these modes. In “Sport” mode, the battery charge is always maintained at a minimum level to ensure there are sufficient e-boost reserve capacities when needed.
“Sport Plus” mode is all about maximum performance and allows the Panamera to reach its top speed of 278 km/h. This mode also recharges the battery as quickly as possible with the help of the V6 biturbo engine.
The Panamera 4 E-Hybrid is now available for order in Germany, with prices starting at EUR 107,553 including VAT. The first units in Europe will be delivered from mid-April while deliveries in all other continents will follow next year.
