Panamera 4 E-Hybrid Revealed
Porsche will unveil the all-new Panamera 4 E-Hybrid at the Paris Motor Show later this month ahead of the first European deliveries expected in mid-April. The plug-in hybrid model will boast all-wheel drive, 462hp and an electric driving range of 31-miles, what’s more it will be capable of returning 113mpg. Prices will start at £79,715 with CO2 emissions of 56 g/km – likely to be of interest to company car drivers.
The electric motor in the new Panamera 4 E-Hybrid boasts 136hp and 295lb ft torque, but unlike its predecessor the accelerator pedal does not need to be pressed 80 percent of the way down to engage the electric motor’s additional power. Rather Porsche says that the electric and petrol motors now work in constant harmony. The petrol engine in question is a 2.9-litre V6 biturbo which alone produces 330hp and 332lb ft torque. In combination the two power units deliver 516lb ft torque, firing the Panamera 4 E-Hybrid to 62mph in 4.6 seconds and onto a top speed of 173mph.
Talking of top speeds, the Panamera 4 E-Hybrid debuts Porsche’s ‘E-Performance’ system which is said to utilise electrical energy to hike the hybrid’s capabilities at VMAX. The advent is also said to deliver ‘more power, more driving fun, and lower fuel consumption’. Also debuted on the car is a new generation of Porsche’s hybrid module said to differ with the electro-hydraulic system used by its predecessor. The decoupler system on the new Panamera now operates via by an electric clutch actuator, serving to sharpen its responsiveness. As on the other second-generation Panamera models, the new eight-speed PDK transmission appears, also aiding performance and driving dynamics.
While the same liquid-cooled lithium-ion battery technology appears in this new hybrid (the battery is located under the boot floor), its capacity has increased from 9.4 to 14.1 kWh, yet its weight remains the same. A full charge via a 230-V, 10-A connection will take 5.8 hours, or 3.6 hours using the optional 7.2 kW on-board charger and a 230-V, 32-A connection. The charging process can be started using a timer via the PCM system or through the Porsche Car Connect app. The 4 E-Hybrid is also fitted with auxiliary air conditioning to cool or heat the passenger compartment during charging as standard.
As we’ve already seen, the second-generation Panamera benefits from the newly-designed ‘Porsche Advanced Cockpit’, with slick touch-sensitive panels. The 4 E-Hybrid adds to that a power meter displaying data such as the amount of electrical energy currently being consumed, as well as any energy recovered through recuperation techniques. The 12.3-inch touchscreen PCM can display hybrid-specific information too, a boost and hybrid assistant shows both the available energy for boosting, and information relating to the regulation of the car’s electrical power.
Sport Chrono is standard issue on the Panamera 4 E-Hybrid, the now familiar mode switch that comes as part of that package includes the usual settings, but also incorporates hybrid-specific options: E-Power, Hybrid Auto, E-Hold and E-Charge. For example the new Hybrid Auto mode puts the car into an ultra efficient state, while E-Hold allows drivers to consciously conserve electric power for use at their command. Also fitted as standard is Porsche’s three-chamber air suspension system.
The global reveal of the new Panamera 4 E-Hybrid will take place on Thursday 29th September 2016. In the meantime you can read our first drive report on the existing versions of the all-new Panamera in our October issue, available to buy in print and digital formats now.
