Sliding into the not too distant future

It would be easy to dismiss the Mercedes-Benz Vision EQXX as the latest unrealistic electric concept car of any kind. At first glance, its ultra-futuristic styling and high range / efficiency goals do not meet the standards of production vehicles.

But Mercedes Already said Many of the car’s elements (if not the exact car itself) will probably go into mass production in 2024.

This makes Vision EQ XX more serious only after spending an afternoon with a prototype in Los Angeles last week. The cars on display are different from the show cars that Mercedes unveiled earlier this year. This version I saw was just an exterior concept, but there are other cars in Germany with a complete interior. That is, there is no pillar-to-pillar hyperscreen inside and no solar roof, but the car on display shows some of the active aerodynamic elements that help the Vision EQ XX achieve a very slippery drag coefficient of 0.17. I was able to. This is a Mercedes EQS 0.20 Cd, Volkswagen XL1..

A small set of active grille shutters underneath the front bumper sends air through the channels that exit the hood and opens only when further cooling is required. The air flows over a small cooling plate on the underside of the car. There is also a deployable rear diffuser that descends and stretches when the EQXX is driving and retracts itself when parked to prevent damage when stretched fairly low behind the vehicle. Even the logo on the front is drawn on top, not in relief. This speaks to philosophy rather than concrete merit.

Mercedes says it could have been made even more slippery by adding something like a wheel cover, but decided that the design elements in particular were too unrealistic. This means that the rest of the EQXX’s styling is rooted in some reality, and you can foresee what the future Mercedes EV will look like, especially for small and medium-sized cars on the next-generation Mercedes-Benz. Modular architecture (MMA) platform under EQXX.

Making a car very slippery has ancillary benefits, from expanding range to reducing the load on the battery. Passive cooling.. Mercedes engineers said that at EQXX, you really have to find a way to generate heat to make the battery more efficient, and you need to add insulation instead of extra cooling. To reduce friction, EQXX also wears low rolling resistance tires specially developed by Bridgestone and hubcaps that are more aerodynamic than standard rims.

Not having to add a cooling system helps to keep weight down. This is another point that Mercedes has put particular emphasis on in addition to the aerodynamics of the car. It starts with a battery that produces about the same power as an EQS battery pack, but due to its high energy density, it is halved in size and reduced in weight by 30%. Mercedes has also confirmed that this is a battery pack of the same size found in first-generation vehicles on the MMA platform, but output and capacity may vary.

Also increasing the lightness of the vehicle is the wider use of Mercedes’ bionics component process. It was first used in 2020 S-Class strut tower production vehicles, reducing the weight of parts by half. Instead of simply casting parts of uniform thickness, computer processes are used to identify where the structure is more stressed and where it can be thinned to reduce weight and save raw materials.

This process was applied to EQXX in large form for the first time, casting the entire back third of the subframe into one piece (see photo above). The end result was a large metal part that looked like an alien structure in a science fiction movie, with holes and notches here and there. However, Mercedes engineers have assured me that it is not only light (light enough to lift one side with one hand), but also strong enough to withstand the company’s stringent safety standards.

The result is a powerful combination of lightness and aerodynamics, but what Mercedes engineers are most proud of is the efficiency of the drivetrain. The energy efficiency from the cell to the wheel is 95%, but most EVs hover around 90%. Most of this loss is heat, but engineers can halve it, and this efficiency makes EQXX charging more efficient. Very little power is required to drive a car, so a quick charge of just 15 minutes can add 186 miles of cruising range.

Most notable is the Mercedes 621, which is an estimate of real-world miles per charge. This is the number we plan to test next month on highways and public roads from Germany to the Mediterranean. Keep in mind that the test will show us how accurate the projection is and what the MMA platform can do in the future.

The show car didn’t have an interior, but was shown a preview of what the EQXX pillar-to-pillar 47.5-inch hyperscreen would look like and feel. Instead of the existing hyperscreen settings that provide three different screens behind a piece of glass, this is a single screen that spans the entire dashboard. In some respects, it’s not much more overwhelming than the hyperscreen experience with EQS and future EQE. The information can be further expanded and the game engine is used to enhance the visuals of the system, making the graphics feel more realistic.

For projects that took only 18 months from start to run, Vision EQ XX feels rigorously and based on the rapidly approaching reality with innovations that can be easily applied to the Mercedes EV lineup over the next few years. increase.
