New Mercedes E-Class due in 2023 with all-electrified engines

The double-wishbone front and multi-link rear suspension has been modified to fit the new dimensions of the platform structure. It will be offered in combination with an optional air suspension and, for the first time on the E-Class, a rear-wheel steering system offering up to 10deg of steering at the rear.

The engines, mounted in their traditional longitudinal position, will be reduced in number and – in selected models – capacity, too.

Officials have hinted that the existing twin-turbocharged 4.0-litre V8 in the E63 will no longer be offered. As in the smaller C63, due out in 2022, its place will be taken by a highly strung turbocharged 2.0-litre four-cylinder, the M139, with plug-in hybrid assistance for a total output of up to 600bhp.

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 allows them to meet upcoming 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.
