The engines of the Mercedes-Maybach S-Class come from the Mercedes-Benz portfolio and are in part electrically assisted. Electrification is by an integrated second-generation starter-generator (ISG). This provides a boost of up to 15 kW, facilitates efficient “gliding” when driving at constant speed, makes the start/stop experience even more comfortable and makes the drive system more efficient overall. All-wheel drive is always standard equipment.
The 9G-TRONIC transmission was developed further and adapted for the ISG. The electric motor, the power electronics and the transmission cooler have now moved into or onto the transmission. In conjunction with ISG, it was possible to eliminate the entire two-piece belt drive, as an electric refrigerant compressor is used. This means that even when the engine is not running (start/stop and gliding phases), the interior can be efficiently and comfortably climatised.
An exhaust system with a petrol particulate filter configured for the engine variant is used to clean the exhaust gases. Pressure and temperature sensors, as well as the latest oxygen sensors, ensure efficient exhaust treatment throughout the characteristic map.
