The new Mercedes-Benz AMG E 53 Estate - E as in efficiency- electrification of the powertrain

"With the model update of the E-Class, the electrification of the powertrain takes another big step. Available are seven models as plug-in hybrids (diesel and gasoline, sedan and station wagon, rear- and all-wheel drive). The range of highly efficient, low-emission, high-performance engines will cover a power spectrum from 115 to 270 kW for the gasoline models, and from 118 to 243 kW for the diesel powertrains. For the first time, a second-generation four-cylinder gasoline engine (M 254) with integrated starter generator (ISG) with up to 15 kW additional power and 180 Nm more torque will complement the engine portfolio. Models with this unit will have a 48-volt electrical system. Recuperation and the ability to "sail" with the engine switched off make the gasoline engine highly efficient. In the M 254, Mercedes-Benz has for the first time combined all the innovations of the modular engine family of 4- and 6-cylinder gasoline and diesel engines in a single unit. These include the NANOSLIDE® cylinder coating, CONICSHAPE® cylinder honing (trumpet honing) and exhaust gas aftertreatment placed directly on the engine. A completely new feature is the segment charger with flood connection, a further development of twin-scroll technology, for even more spontaneous response to turbocharging. An additional electric compressor quickly builds up the boost pressure when required - especially at low engine speeds - and thus contributes to a very dynamic response. The inline six-cylinder gasoline engine (M 256), available for the first time in the E-Class, also features ISG. The engine range is rounded off by the six-cylinder diesel (OM 656). Exhaust gas aftertreatment has been extended for this engine and the four-cylinder version (OM 654)."
