Porsche has unveiled the fourth model in the Panamera line: the Panamera 4 E-Hybrid with controlled all-wheel drive and an electric range of 31 miles.
The vehicle generates 462 horsepower combined with fuel consumption of over 90 miles per gallon.
The new Porsche plug-in hybrid always starts in purely electric mode and drives without generating any local emissions with a maximum speed of 86 mph. The four-door hybrid sports car breaks the 62 mph 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 Strategy
The new Panamera 4 E-Hybrid features a hybrid strategy based on the 918 Spyder. The 918 Spyder’s 887 horsepower 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 is made available as soon as the driver touches the accelerator pedal. On the predecessor model, the pedal needed to be pressed at least 80 percent of the way down to unleash the additional power of the electric drive. Now, the electric motor and petrol engine interact in perfect harmony from the very outset.
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 generates an impressive boost scenario based on electric motor and turbochargers.
In the Panamera 4 E-Hybrid, the electrical energy is also used to increase the car’s top speed.
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, according to Porsche.
The high-voltage battery takes 5.8 hours to fully charge via a 230-volt, 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 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), the Panamera 4S (324 kW/440 hp), the Panamera 4S Diesel (310 kW/422 hp) and the Panamera 4 E-Hybrid.
