This is how sustainable the Mercedes EQE is

The production of the high-voltage battery and the external charging processes during driving are essential factors when it comes to the life cycle assessment of an electric car.

Mercedes-Benz bases its model calculations on two different assumptions: The standard scenario considers the country-specific electricity mix for charging the high-voltage battery and for manufacturing the battery cells. In the regenerative scenario, on the other hand, renewable energy is used.

Both scenarios are based on a mileage of 250,000 kilometres for the EQE electric sedan  The greatest savings can be achieved by charging electricity. Without green electricity, a good 13.8 tonnes of CO2 are produced over a mileage of 250,000 kilometres. With renewable energies, the traction current emissions drop to only 0.2 tonnes.

By comparison, the life cycle analysis of the current diesel-fuelled E-Class (model E 220d) shows a total of 36 tonnes of CO2 for a mileage of 250,000 kilometres. More than 25 tonnes of this come from driving and burning fossil fuel, but only if the NEDC consumption of 3.9 litres of diesel is also achieved. The diesel model's CO2 emissions will be several tonnes higher.

In the case of the predecessor generation of 2009, the figure was as much as 51 tonnes of CO2, almost 40 tonnes of which came from driving, also taking into account the consumption according to the NEDC measurement, which is almost impossible to achieve in practice.

Other aspects of the EQE's sustainability at a glance:

• With its arched one-bow design and extensive aerodynamic measures, the EQE Sedan achieves a very good cd value of 0.22.
• 184 components with a total weight of more than 78 kg can be made proportionately from resource-saving materials (plastic recyclates and renewable raw materials).
• The cell chemistry of the battery generation has also been optimised in terms of sustainability: The active material consists of nickel, cobalt and manganese in a ratio of 8:1:1. This reduces the cobalt content to ten per cent. Responsibly sourced and processed raw materials are an essential basis for a sustainable electric fleet for car manufacturers like Mercedes-Benz.
• The majority of suppliers, who account for almost 90 per cent of the annual purchasing volume, have already signed an ambition letter. In this letter, they declare their willingness to supply only parts produced in a CO2-neutral manner in the future.
• Since 2022, all Mercedes-Benz passenger car and van plants worldwide have been producing in a CO2-neutral manner.
