The Panamera S E-Hybrid is a parallel plug-in hybrid. This means that it can be powered by the combustion engine alone, by the electric machine alone or by both units working together. In this way, it is able to exploit the power generated by both propulsion units – a concept that’s been proven since 2011. What’s new is that the high-voltage battery is recharged in around 3.8 hours via direct connection to an electricity socket or, whilst driving, through the process of brake energy recovery known as recuperation, or via the combustion engine. Thanks to innovative lithium-ion technology, its capacity of 9.4 kWh means that is also stores much more energy. The battery is maintenance-free and covered by a six-year warranty.
The 3.0-litre supercharged V6 engine generates 245 kW (333 hp), the electric motor 70 kW (95 hp). Combined, they deliver 306 kW (416 hp) to the road at 5,500 rpm. With both drives working together, the Panamera S E-Hybrid accelerates from 0 to 100 km/h in a mere 5.5 seconds. Fuel consumption (NEDC) is remarkably low at an average of 3.1 l/100 km, as is the CO2 emissions figure of 71 g/km.
The operating range of the hybrid drive begins with emission-free, quiet driving up to a maximum speed of around 135 km/h and a range of approximately 36 km (in NEDC). The combustion engine is fired automatically when necessary as determined by the operating strategy or actively in response to the driver depressing the accelerator pedal beyond a specially defined pressure point. The kick-down point, however, enables the maximum power output available from both propulsion units to be purposefully exploited as and when the driver chooses. In e-boost mode, the combustion engine provides assistance for the electric drive – providing a sporty shunt into the future. In coasting mode, the combustion engine is decoupled to allow the car to glide for some distance under its own momentum – thereby further reducing the fuel consumption.
In summary, the E-Hybrid concept promises one thing above all: sporty performance with utmost efficiency. The workings of the combustion engine, electric motor and high-voltage battery are synchronised by the electronic engine management. All processes run smoothly and harmoniously, leaving you to concentrate on what matters the most: driving.
