Mercedes-Benz has increased the official CO2 emissions for the E-Class as a result of new WLTP emissions testing.

The revised figures - obtained via the new testing cycle then converted back to an NEDC equivalent - have been announced alongside a larger choice of petrol and diesel engines.

Official emissions for the E-Class saloon have increased from a base-level 102g/km to 122g/km.

The popular E 220d AMG Line now officially emits 127g/km, rising from 112g/km under the old NEDC test cycle.

All new cars launched since September 2017 have been required to be tested under the new regime and the Government has set a target for all manufacturers to re-test existing models by September 2018.

The revised test is designed to represent the real-world emissions of a vehicle and therefore produces an increased figure.

Mercedes-Benz has also published revised figures for the GLC SUV.

Volvo published revised figures for its entire model line-up last week and more manufacturers are expected to release figures in the coming months, prior to the September deadline.

Alongside the revised emissions figures, Mercedes-Benz has introduced a new, more powerful, diesel engine to the range.

The E 400 d, which replaces the E 350 d, uses a new 3.0-litre straight six turbodiesel engine with an output of 340PS and 700Nm. It delivers 48.7mpg emits 154g/km of CO2. Acceleration from zero to 62 mph takes 4.9 seconds.
