Both models always start in electric E-Mode (exception: outside temperatures below -10 degrees). This is because the battery, which is almost twice as large at 19.7 kWh, reserves a greater amount of energy than before for this. The Passat switches automatically to Hybrid mode only when the speed exceeds 140 km/h, if the driver requests a large amount of power (e.g. kickdown) or if the battery has too little residual capacity for continuous electric operation; the driver can also make this switch manually if required. In addition, the driver can choose from the four driving modes Eco, Comfort, Sport and Individual. Here, Volkswagen has significantly enhanced and adapted its hybrid strategy. In Eco mode, the Passat is now kept in E-Mode even during strong acceleration; in this mode, the car drives practically like an electric vehicle. The TSI engine is switched on in Eco mode only at almost full load or if the battery level is low. In this mode, this now takes place without the gearbox shifting down a gear, ensuring that the TSI is integrated in a very comfortable and efficient way. However, if the driver switches to Comfort, Sport or the correspondingly configured Individual mode, they can also activate downshifts spontaneously by means of the accelerator pedal position and access the full power of the TSI. As described above, the electric drive motor is supplied with energy by a new 19.7 kWh battery (net energy content). At DC quick-charging stations, it can now be charged with up to 50 kW4. eTSI5, TSI and TDI – multi-faceted efficiency The range of drive systems is supplemented by a mild hybrid drive (1.5 eTSI5), turbocharged petrol engines (2.0 TSI) and turbocharged diesel engines (2.0 TDI). The entry-level version is a 48 V mild hybrid drive with an output of 110 kW (150 PS)5, which is new in the product line. The power spectrum of the TDI also starts at 110 kW (150 PS)6.
