The E 300 e plug-in hybrid has an electric output of 95kW (129hp) and an all-electric range of up to over 100km (WLTP standard).
The combustion engines are four and six-cylinder units from the current modular Mercedes-Benz engine family FAME (Family of Modular Engines).
In addition to turbocharging, both the diesel and petrol engines an Integrated Starter-Generator (ISG), and are therefore mild hybrids.
Thanks to a new battery, the power of the electric motor has been increased from 15 to 17kW and the boost torque to 205Nm.
The new E-Class Estate's design has also changed - the roofline is more dynamically designed compared to its predecessor.
It's wider by 28mm and this gives the rear passengers even more space: elbow room in the rear is increased to 1519mm.
The wheelbase has increased by 22mm to 2961mm.
As a result, those sitting in the back enjoy more knee room and leg room.
The load compartment can be expanded from 615 litres to up to 1830 litres.
In the plug-in hybrid model, the luggage capacity is 460–1675 litres.
With the Digital Vehicle Key, the E-Class Estate can be started and locked simply by the driver carrying a compatible device with them.
Key sharing is also possible: various digital channels can be used to invite family members or friends to use the E-Class Estate.
In doing so, the vehicle owner can assign different rights, granting only access to the vehicle or also allowing it to be driven.
The vehicle can recognise several users at once, and the Digital Vehicle Key can be shared by up to 16 persons.
The entertainment programme in the E-Class Estate is more interactive than ever as software experts at Mercedes-Benz have developed a new compatibility layer that allows the installation of third-party apps.
These apps include the entertainment platform "TikTok", the game "Angry Birds", the collaborative application "Webex" and the office application "Zoom" as well as the browser "Vivaldi" and the podcast app "Pocket Casts".
Another new feature is a selfie and video camera (part of the optional MBUX Superscreen) on top of the dashboard.
Mercedes-Benz is working on the use of artificial intelligence (AI) so that the car learns which comfort systems vehicle occupants use repeatedly.
Given the same circumstances, the aim is for AI to automate such functions.
Customers will be able to use templates for standard routines. They also have the option of creating routines themselves.
The new E-Class Estate features the Agility Control suspension and single-chamber air suspension on the rear axle as standard.
The latter features a compact design, maintains ride comfort even with a full load on board and ensures that the vehicle remains horizontal even when laden.
The all-round Airmatic air suspension with ADS+ continuously adjustable damping is available as an option.
Also, many E-Class Estate components are made partly from resource-saving materials (recyclates and renewable raw materials).
Upholstery made of undyed alpaca wool combined with a recycled material is used for the basic seat.
For the first time, certified recycled raw materials are used in the foam of the seats according to the "mass balance approach".
In terms of their properties, they do not differ from raw materials produced from crude oil.
Also, the standard Active Parking Assist can now be started intuitively via the touchscreen.
Automated parking and unparking is much faster than before, as the speed has been increased to up to 4 km/h.
