The next-generation Mercedes-Benz E-Class is due to land in 2023 with a range of all-electrified engines.
Known internally by the codename W214, the new E-Class follows an evolutionary path, with development focused around refinements to its platform, electric architecture and engines.
Its electric architecture is being heavily upgraded to support new functions that include level three autonomous driving potential in countries where it is permitted, together with 5G connectivity that allows high-speed over-the-air software updates for the first time.
With the all-electric Mercedes-Benz EQE offering electric drivelines, the 2023 combustion-powered E-Class will stick with electrified versions of today’s four- and six-cylinder engines.
The existing M254 four-cylinder petrol and OM654 four-cylinder diesel units will be offered exclusively with an integrated starter-generator and 48V electrical system as well as changes to their exhaust system that allow them to meet EU7 emission regulations.
The turbocharged 2.9-litre in-line six-cylinder M256 petrol and turbocharged 3.0-litre in-line six-cylinder OM656 diesel units are planned to receive similar upgrades and will be offered with both mild-hybrid and plug-in hybrid functionality with up to 435bhp and 330bhp respectively.
All plug-in hybrid versions are set to receive a 28.6kWh battery, the same unit used by the Mercedes S580e, to give them an electric range of over 62 miles.
Every engine is set to be combined with a standard nine-speed torque-converter automatic gearbox. Rear-wheel drive will feature on lower-end models, with Mercedes-Benz’s 4Matic four-wheel drive system set to appear on more powerful models, including those from AMG.
Styling-wise, the new model adopts a look similar to the latest Mercedes-Benz S-Class, with a bolder front end comprising more angular headlights and a large chromed grille. While heavily disguised on the prototype captured here, the rear is described as a mixture between the S-Class and new Mercedes-Benz C-Class.
