The figures retain the car’s position as the most efficient model in its class, due to its unique drivetrain. Under the bonnet is the 2.1-litre 202bhp diesel engine from the E250 CDI, but combined with an electric motor between this and the transmission to offer short-range electric cruising, high-speed electric “sailing” at up to 96mph and 231bhp using both together.

Because the lithium ion battery is under the bonnet, there are no alterations to the bodyshell unlike its executive rivals, which means the E-Class Hybrid can also be offered as an estate. This has had a small increase from 62.7mpg to 64.2mpg in the facelifted car, while CO2 emissions remain at 116g/km.

The facelift includes a completely redesigned front end with single-piece headlamps and a new grille, while the outgoing car’s muscular rear arch line has been replaced with a smoother side profile. New rear lights and a  revised interior, featuring a two-part wood or aluminium trim panel, are also included in the refresh.

New engines include two direct injection petrols with 184bhp and 211bhp, which both emit 135g/km. The E-Class also debuts 11 new or optimised assistance systems due for the next generation S-Class, including a 3D camera system which scans 50 metres ahead to help prevent accidents.
