The Mercedes Vision EQXX is an energy efficiency study car

The goal is to achieve a range of 1,000 kilometers, but not by increasing the capacity of the batteries.

It was no surprise that Mercedes unveiled the Vision EQXX study car at CES, and they have repeatedly hinted that they are preparing for it. It was no secret that the most important promise of the concept, the goal was to achieve a range of 1,000 kilometers, which, according to the manufacturer, of course, was achieved. However, the point is not necessarily to be found in this, but in the fact that only a 100 kW battery pack is used for all this, which means that the study is capable of consuming 10 kWh / 100 km, which is not the case in this size class but among smaller electric cars. would also be outstandingly good.

This is much harder to achieve than you might think, not only is the Vision EQXX with a special Bridgestone tire and a shape factor of 0.17, but the battery pack itself is different from other cars in the company. A battery with a similar capacity (such as the one in the EQS) is 30% lighter and takes up half the space, and all of this comes with a redesigned powertrain that is 95% more efficient, so 95% of the energy taken from the battery is the gets to the wheel. (For an internal combustion engine, this is usually 50%.)

Environmental awareness is built on Vision EQXX from recycled plastics, 3D-printed elements and plant-based materials that can be seen in the materials used and in production. The brake discs are made of aluminum alloy (for weight reduction), the ultra-thin solar panels in the roof add enough energy to the system for an additional 25 kilometers (this is stored in a separate lithium-iron phosphate battery in the car, the lights and the on-board system). and development took only 18 months, one of the reasons being that the design was completely digital.

Weighing in at just 1,750 kilograms, the car’s 204-horsepower doesn’t want to compete with the muscle wines of electric cars, as energy efficiency has been the guiding principle. Along the way, the car’s thermal management has been put on a whole new footing, meaning that the energy used for both cooling and heating can be solved with the least power required by Vision EQXX’s “cooling-on-demand” technology, which uses all kinds of cooling pipes, aerodynamics and fans. keep the battery at an ideal temperature. This solution also includes a large heat sink located on the floor plate, as well as a redesigned heat pump system that solves the cabin temperature by making ideal use of the outside air and the residual heat of the battery. This was necessary because, in the case of electric cars in general, it visibly throws down consumption.

Inside, the passenger compartment is clean, full of vegan leather and vegan carbon fiber, bamboo was used on the floor, and a material called DINAMICA, made from 38% recycled PET bottles. The body of the car is made of martensitic steel alloy, the doors are made of carbon and fiberglass, but it’s also hard to list how many elements the Vision EQXX has that are different from what we’ve been used to. For gourmets we recommend the manufacturer official description (English).

The internal system relied heavily on artificial intelligence solutions and the hardware also has NPUs. Mercedes says this results in five to ten times more efficient voice control. The complete dashboard features an 8K mini-LED display (47.5 inches diagonal, 7680 x 660 pixels resolution) with brand new 3D navigation. The display can be lightened and darkened at 3,000 individual points to save energy, plus the on-board system itself continuously treats the driver on how to drive even more energy-efficiently.

Of course, the very detailed press material does not reveal a lot of important things (for other cars): what are the driving dynamics parameters (acceleration, top speed) and when, where and for how much it will be available for purchase. The answer to the latter questions is clearly that the Vision EQXX is a study car, meaning it will not hit the street in this form, but the technologies and design and IT solutions presented here will be available in Mercedes in the near future.
