The electromechanical brake booster guarantees a variable combination of deceleration by electrical energy recuperation and mechanical braking. The brake pedal characteristic and pedal force remain identical here. The brake pedal feeling has been further optimised on the new
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
Optimised modes for electric driving experience
The four driving modes ‘E-Power’, ‘Hybrid Auto’, ‘Sport’ and ‘Sport Plus’ are selected as usual using the mode switch in the standard Sport Chrono package. In addition, the two modes, ‘E-Hold’ and ‘E-Charge’, which are activated with
To further enhance the electric driving experience, the modes in which the high voltage battery is charged during driving have been optimised. The new
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
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.
The E-Charge mode of the new
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
