The electronic power super visor - 4 automatically manages the operation of the two power units (Diesel and electric) to provide the lowest consumption. An inverter and a transformer are needed to manage the electric power. The inverter acts on the torque of the electric motor, by regulating the current coming from the high voltage battery pack. Its operating range is between 150 and 270 volts. The transformer converts the 200 V of the battery pack to 12 V, to power the vehicle's ancillary systems.
The alternator-starter motor - 5 assures the Stop & Star t function which allows the Diesel engine to be put into standby during stops (traffic lights, a stop, or in a traffic jam, for example) or during phases of running in all-electric mode. The stopping and restarting of the Diesel engine is done in a way that is instantaneous and transparent for the driver. It also provides additional charging of the batteries (4x4 mode for example or under-charged high voltage battery).
The electronic gearbox - 6 provides, in automatic mode, significant savings in fuel consumption compared to a conventional manual gearbox, thanks to its electronic control system. It also offers improved driving pleasure with the possibility at any time of choosing the gear changing mode: automatic or manual, using the paddles located behind the steering wheel.

Reducing consumption - Fuel
QuestionAnswer
How can I optimise my fuel consumption? Give preference to Auto mode as it selects in the best way the "driving energy source" to use in order to reduce fuel consumption. You should also adapt your driving style to the characteristics of hybrid vehicles to get the best out of it, for example by taking your foot off the accelerator pedal rather than braking and by anticipating decelerations (entering a built-up area, stop at traffic lights, stop at halt signs, ...).
Why do I not manage to reduce my fuel consumption even though I often drive in ZEV (Zero Emissions Vehicle) mode?
It is not ZEV mode but Auto mode that is the most appropriate for reducing fuel consumption, as it selects the best "driving energy source". ZEV mode (100% electric operation) can reduce fuel consumption in some cases. However, recharging the traction battery has an energy cost. This is why we recommend using Auto mode more often.
Why does the trip computer sometimes display the bars for 28 mpg (10 litres) consumption in town?
The current fuel consumption displayed may appear high when the distance covered is very low, but this generally has very little impact and the true average fuel consumption will remain low. In town, your hybrid retains very good fuel economy (of the order of 35% better than a non-hybrid vehicle).
Why is my battery rarely fully charged? A partly charged battery is normal operation (4 to 5 bars on average in Auto mode). This allows some capacity to be left free for the recovery for energy when going downhill or taking when your foot off the accelerator.
Why are there so may fuel alert messages when starting to use the reserve? To encourage you to refuel as soon as possible and avoid the loss of hybrid functions.
