Longer range and more intelligent energy recuperation

The new Panamera 4S E-Hybrid models utilise the driveline architecture of the previous hybrid models. The heart of this is an electric motor integrated into the eight-speed PDK dual-clutch transmission, which contributes an output of 100 kW (136 PS) and a torque of 400 Nm. Intelligently combined with the 324 kW (440 PS) 2.9-litre V6 biturbo engine, the newly developed Panamera 4S E-Hybrid generates a system output of 412 kW (560 PS) and a maximum system torque of up to 750 Nm. In combination with the standard Sport Chrono package, this results in outstanding performance statistics: the standard sprint to 100 km/h is achieved in 3.7 seconds. The maximum speed is 298 km/h.

The electric motor draws its energy from a high-voltage battery installed at the rear. To achieve a long electric range and extend the reserve capacity for electric boosting, the battery’s gross capacity has been increased from 14.1 to 17.9 kWh compared with the previous hybrid models thanks to optimised battery cells. This corresponds to an increase of exactly 27 per cent. The Panamera 4S E-Hybrid therefore now boasts an all-electric range according to WLTP EAER City of up to 54 km (NEDC: up to 64 km). The installation space for the battery beneath the load compartment floor remains compact, providing spacious luggage volumes from 403 to 1,242 litres in the sports saloon (Sport Turismo: 418 to 1,287 litres).

The intelligent Hybrid Auto mode offers the greatest operating efficiency for urban and cross-country driving. For the best possible combination of the electric motor and combustion engine, the optimum operating strategy is continuously derived from information relating to driving profile, state of charge, topography, speed and navigation destination. All-electric driving is used in situations where, in terms of overall efficiency, it is the most appropriate option. The Hybrid Auto mode of the new Panamera 4S E-Hybrid adapts optimally to the driver’s habits. When route guidance is activated, the electric drive is used more intensively during urban driving in particular. The high-voltage battery is charged more on sections of road where the combustion engine is active.

In E-Hold mode, the state of charge of the high-voltage battery is maintained at the current level as usual. This means that the energy of the battery can be used at a later time for electric driving or boosting. In E-Charge mode, the combustion engine charges the battery when driving by generating a higher output than required for the current driving situation. This so-called load point shift provides the driver with the option of predictively increasing the electric range.

In both performance-oriented Sport and Sport Plus modes, the combustion engine is always in operation. Sport mode offers extremely sporty vehicle characteristics for fast driving on country roads and motorways; in this mode, the drivetrain and chassis are switched to the Sport setup. The battery is charged to a minimum level to be able to provide a sufficient amount of boost for the sporty driving style.

In Sport Plus mode, the focus in all Porsche models is on maximum sportiness: the drive and chassis are adapted for high performance. On the Panamera 4S E-Hybrid models, Sport Plus mode additionally differs from Sport mode due to the fact that the battery is charged as quickly as possible to 80 per cent. Specification of a constantly high charging capacity of 12 kW means that maximum boost availability is reached even faster. The reduction in the target charge level ensures the availability of the maximum recuperation power.
