The new variant S 560 e boasts a low fuel consumption of 2.1 litres per 100km and an all-electric range of around 50km.
The hybrid drive system in the S 560 e combines the 270kW (367hp) of the V6 petrol engine with a 90kW (122hp) electric motor.
The third-generation hybrid transmission evolved on the basis of the nine-speed 9G‑Tronic Plus automatic transmission.
The torque converter, clutch and electric motor are housed in the innovative hybrid drive unit and the compact design was achieved by integrating and connecting the separating clutch, torsional vibration damper and torque converter lock-up clutch within the rotor of the electric motor.
The torque converter with its powerful and highly efficient hydraulic circuit offers the customary smoothness when pulling away in hybrid mode.
Developed together with Bosch as part of the EM‑motive joint venture, the electric motor was specially designed for the 9G‑Tronic plug-in hybrid transmission.
The new, significantly enhanced power electronics have allowed further increases in output and torque.
The electric output of 90kW and 440Nm of torque contributes to the effortless driving sensation in the S‑Class.
Although the physical size of the battery remains unchanged, its capacity has been increased to 13.5kWh.
Evolving the cell chemistry from lithium-iron-phosphate (LiFePo) to lithium-nickel-manganese-cobalt (Li-NMC) allowed the cell capacity to be increased from 22 to 37Ah.
The highly efficient battery system in the S‑Class comes, for the first time, from the wholly owned Daimler subsidiary Deutsche ACCUMOTIVE.
The power electronics are now housed in the engine compartment.
Despite an increase of around 50% in its energy content, the dimensions of the new battery are smaller than those of its predecessor, resulting in the boot capacity being increased from 395 to 410 litres.
