New hybrid model of the Porsche Panamera launched
The Paris Motor Show will see Porsche unveil the fourth model in the Panamera line: the Panamera 4 E-Hybrid with controlled all-wheel drive and an electric range of 50 kilometres.
The vehicle generates some 340 kW (462 hp; combined fuel consumption 2.5 l/100 km; CO2 emissions 56 g/km; energy consumption 15.9 kWh/100 km) of system power and 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. At Porsche, the term "hybrid" is synonymous with not only sustainable mobility, but performance too – a fact proven not least by the victory of the 919 Hybrid in the 24 Hours of Le Mans race in 2015 and 2016. This philosophy is now also defining the Panamera 4 E-Hybrid.
The new Porsche 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. And yet this Panamera too is a sports car among the luxury saloons: The all-wheel Porsche achieves a top speed of 278 km/h and delivers a system torque of 700 Nm from stationary without hesitation. The four-door hybrid sports car breaks the 100 km/h barrier in just 4.6 seconds. The torque is transferred to all four wheels and the standard three-chamber air suspension ensures an optimum balance between comfort and dynamism at all times.
New hybrid module and fast-shifting eight-speed PDK
Together with the V6 petrol engine decoupler, the electric motor heralds the new generation of the Porsche hybrid module. In contrast to the electro-hydraulic system of the predecessor model, the decoupler on the new Panamera is actuated electro-mechanically by an electric clutch actuator (ECA), resulting in even shorter response times.
As on the other second-generation Panamera models, a new, extremely fast and efficient-shifting Porsche eight-speed Doppelkupplung (PDK) transmission is used to transmit the power to the all-wheel drive. This transmission replaces the eight-speed automatic torque converter transmission on the predecessor model.
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.
Ultimate efficiency in “Hybrid Auto” mode
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.
New model offers a globally unique combination of dynamism and comfort
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 first units in Europe will be delivered from mid-April. Deliveries in all other continents will follow in 2017. The plug-in hybrid version is the fourth model in the new Porsche Panamera line; all models are all-wheel drive. The line now consists of the Panamera Turbo (404 kW/550 hp; combined fuel consumption 9.4 – 9.3 l/100 km, urban 12.9 – 12.8 l/100 km, extra-urban 7.3 – 7.2 l/100 km; CO2 emissions 214 – 212 g/km), the Panamera 4S (324 kW/440 hp; combined fuel consumption 8.2 – 8.1 l/100 km, urban 10.2 – 10.1 l/100 km, extra-urban 6.8 – 6.7 l/100 km; CO2 emissions 186 – 184 g/km), the Panamera 4S Diesel (310 kW/422 hp; combined fuel consumption 6.8 – 6.7 l/100 km, urban 7.9 l/100 km, extra-urban 5.9 – 5.8 l/100 km; CO2 emissions 178 - 176 g/km) and the Panamera 4 E-Hybrid (340 kW/462 hp system power). These four models represent a fusion of sports car and passenger car to form a Gran Turismo concept offering a globally unique combination of dynamism and comfort.
