This is what the most efficient Mercedes of all time looks like

The Consumer Electronics Show in Las Vegas was a must for all nerds and technology fans for years. Because the fair was used by countless providers to present the most spectacular innovations possible. But here, too, the corona pandemic was not without consequences. Last year, for example, the event took place in a purely virtual manner. This year, the organizers actually wanted to return to the classic format. But numerous well-known companies – such as Microsoft, Meta and Amazon – canceled their participation after the corona infection numbers in the United States shot up again. It therefore remains to be seen how spectacular the trade fair from January 5th to 8th will be. Mercedes has also reduced its local activities. Nevertheless, the group used the attention to present the Vision EQXX concept car at a media day. The vehicle should then also be able to be viewed by trade fair visitors on site.

The consumption of a comparable petrol engine would be one liter per 100 kilometers

The specialty of the Vision EQXX is its extremely high efficiency. The engineers involved have calculated that the vehicle could travel more than 1,000 kilometers on one battery charge even in real traffic. However, this is not possible with the help of a particularly large battery. Instead, the vehicle was designed in such a way that it consumes extremely little energy. Specifically, the energy consumption is ten kilowatt hours per 100 kilometers. For those who can’t do much with it: If it were a gasoline engine, the consumption would be around one liter. It is therefore the most efficient Mercedes of all time. However, it is still just a concept car. The vehicle is therefore not ready for series production and has not yet been sold. At least, however, test drives should take place relatively promptly on real roads under realistic conditions. The innovations developed for the concept could then gradually be used in the Group’s series vehicles.

Air resistance and weight have been greatly reduced

But how did the engineers manage to reduce energy consumption so much? In some cases, they screwed on well-known variables. For example, they reduced weight and drag. The designers were inspired by natural shapes and were able to achieve a drag coefficient of 0.17. For comparison: The previous record was held by the Mercedes EQS and was 0.2. In addition, particularly light materials were used in various places. Examples of this are the magnesium wheels or the brake discs made of an aluminum alloy. With the help of expertise from Formula 1, it was also possible to halve the volume of the battery while maintaining the same level of performance. This also resulted in a weight reduction. Thanks to these measures and the use of 3D printing technology, the total weight of the vehicle was reduced to 1,750 kilograms. Here, too, a classification helps: The EQS weighs just under 2,500 kilograms. However, the Vision EQXX cannot be driven at the CES in Las Vegas either.
