The EQXX is only the beginning. Efficiency is the "new currency".
I was very critical of Mercedes during the transformation because they did almost everything wrong. They have given every classic competence out of the house and out of control. But then they came up with the idea to focus on software and efficiency. Maybe the maths will work out and they can hold their own against Tesla and the aggressive Chinese.
But elevating efficiency to the corporate throne will only work with the right technology ; ) I think to myself, and once they have got used to the technology... and chips are the new raw material...
In addition to this, I still assume that the Akida "Hey Mercedes" or MBUX will make the controls smarter in every vehicle and not only in the top models.
"Mercedes is said to be planning a compact electric car with a range of 850 kilometres

In April, as announced, Mercedes-Benz managed over 1000 kilometres on one charge in real road traffic with the electric car technology carrier EQXX (article image). With the technology developed for the mid-size sedan, series-production models are to be realised in a few years that will enable previously unattained long distances on one battery charge.
With the luxury sedan EQS, Mercedes has had the electric car with the currently longest range in its programme since last year. However, the 780 kilometres according to the WLTP standard cost over 100,000 euros. The EQS is the first model series to use the EVA2 electric car platform. Starting this year, the EQE sedan in the E-Class segment and SUV versions of the EQS and EQE will follow, but none of the models is expected to set new range records.
Mercedes is currently building its compact electric cars on architectures developed for internal combustion engines. By the middle of the decade, the first models will be launched on the new MMA platform for compact and mid-sized models. The architecture is specially designed for purely electric cars, but can also accommodate a small combustion engine if required. According to the Handelsblatt, the CLA Coupé could roll off the production line on the MMA as early as 2024, using much of the technology tested in the EQXX - and offering a correspondingly long range.
As a fully electric car, the 2024 CLA Coupé could cover a distance of between 650 and 850 kilometres without recharging, depending on the model. This is what the Handelsblatt has learned from an unnamed insider. The decisive factor for this flexibility, which is still unrivalled in the segment and overall, is said to be "enormously low consumption values" of around ten kilowatt hours. Mercedes recently proved that this is possible with the EQXX: The vehicle came to a very low consumption of 8.7 kWh per 100 kilometres.
However, around 800 kilometres is not supposed to be a new standard at Mercedes. On the one hand, only models like the CLA, which are particularly wind-friendly due to their flat design, are supposed to achieve this. Heavy SUVs that stand in the wind, such as the GLB, will consume significantly more energy. "Of course, aerodynamic drag is the most important factor in real-world consumption," says Markus Schäfer, head of development. He did not want to comment on concrete ranges with reference to the competition.
Efficiency the "new currency"
As with the brand's current electric cars, customers will be able to choose between several battery sizes for the MMA series. However, the decisive factor for the premium carmaker is efficiency - this is the "new currency" of the industry and must be considered in every detail of new vehicle platforms, Schäfer stressed. "What I can take in or out are cells to adjust the range. But the efficiency has to be purely developed."
The trick, he said, is to cover long distances with small energy storage units. The focus on efficiency is advantageous for both customers and vehicle manufacturers; Schäfer spoke of a "win-win situation". Customers would have lower energy costs, and the battery could also be smaller, making the e-car cheaper. But smaller batteries would also benefit Mercedes. "Every kilowatt hour we don't install helps the company to continue to be economically successful."
According to the developers, the battery pack of the EQXX with an energy density of just under 400 Wh/l stores close to 100 kWh of energy with 50 per cent less volume and 30 per cent less weight than the battery pack of the EQS, which has been the leader in this respect so far. The cell chemistry used in the record drive with the EQXX is to be used in production vehicles from 2024. Compared to previous battery systems, the Swabians used "a lot of silicon at the anode", Schäfer explained.
Furthermore, according to the report, Mercedes wants to use its self-developed electric powertrain in the future. This "eATS" has an efficiency of 95 per cent, whereas conventional e-drives only achieve 80 to 85 per cent. With the help of "bionic structures" and larger structural castings, the company wants to save weight and money. Mercedes is also working on drastically reducing the power consumption of the vehicle electrical systems. In future, every watt will count, Schäfer emphasised. Therefore, each component that requires energy should be able to be switched off individually when it is not needed."
