Mercedes EQXX: vision of a four-digit range-range

In terms of average daily mileage, even small e-cars are completely sufficient. But even a radius of several hundred kilometers cannot dispel one concern, especially German customers: the fear of range. Hardly anyone actually makes the trip – but most would love to be able to drive from Berlin to Lake Garda in an instant. Preferably non-stop.

And so the manufacturers are constantly tinkering with even more capacity, with the result that the batteries – and with them the cars – are becoming even heavier. Currently leading: the Mercedes EQS. The exciting brother of the S-Class has officially already covered 784 kilometers – the EQXX study is now even supposed to conquer the four-digit range.

The prototype shows how the future of electric cars is imagined in Stuttgart, announced Daimler boss Ola Kallenius in a statement. And not so much with mass, but with the “most efficient Mercedes of all time”. The solution should not be a mega battery, but material and aerodynamics. While competitor models such as the Nio ET5 announce a power storage unit with 150 kWh, Mercedes is modest with 100 kWh. Inside, however, the big difference is waiting: With the knowledge from Formula 1 and Formula E, the Swabians are relying on a new cell structure, better chemistry and packaging made of carbon instead of aluminum.

The end result is a battery that, according to Daimler, requires half the installation space and a third less weight. Also suitable for the next generation of the small car EQA. The battery should bring the 150 kW engine to a maximum of 140 km/h. And that with “efficiency on a completely new level,” they say. Daimler specifies the average consumption per 100 kilometers as 10 kWh. That’s less than current microcars – and only about half as much as the EQS.

You can see part of this efficiency in the car. With a drag coefficient of 0.17, the silver prototype is the most streamlined production car in the world. The long tail with the decidedly late spoiler lip is particularly striking – supplemented by an extendable floor spoiler. But a lot is hidden under the streamlined shell. For example, Mercedes promises low weight thanks to parts from the 3D printer, a purely electric chassis and solar panels in the roof for an extra 25 kilometers range – but above all record efficiency. 95 percent of the energy from the battery should reach the wheels.

  1. Just impressive! cw 0.17 plus low weight plus 900V plus optimized thermal management. The German engineers take over. Incidentally, a lot of Taycan can be seen in this design. Which is not surprising because it is the electric car for driving fast.

  2. I don’t understand the complaints about larger batteries. Of course, more resources are needed to produce it and the car will be heavier. But there is also a clear plus point: longer service life or. more km per battery because (with similar vehicle consumption) a large 100kWh battery e.g.B. for 300.000km fewer cycles consumed than a 35kWh battery. Because fast charging z.B. with 100kW for a 100kWh battery means a completely different C-rate than for a 35kWh battery. Because fast charging is less necessary with a 100kWh battery than with a 35kWh battery (because the situations where you really need fast charging in everyday use are rarer).
    In the end you have to decide whether you want to pay 300.000km a 100kWh battery (incl. around the cells) “used up” (which can then still have a long second life), or one (or two?) 35kWh battery (each incl. around the cells). And because z.B. triple the battery size in a vehicle does not mean triple consumption when driving.

  3. Even if a 100 kWh battery becomes smaller and cheaper in the future – we cannot stuff all e-cars full with kWh, because vehicles worldwide have to move away from combustion engines and therefore many vehicles have to get by with fewer kWh, e.g.B. small e-city cars with 5-10 kWh or, even better, covered pedelecs on bike lanes as a car alternative with only 0.5-1 kWh.

  4. The topic of batteries is far from exhausted. So far only approx. 5% of all conceivable material pairings systematically examined (source ETH Zurich). In addition, the development of the last 5 years can be summarized as follows for an “elevator pitch”:
    1% less cost, 1% less weight, 1% more capacity, 1% more cycle stability – per month (Source: Lars Thomson – Future matters).
    Even simple minds like CEOs can then remember it more easily.
