One hour after the end of the New Year's holiday, at 1:00 a.m. Beijing time on January 4, Mercedes-Benz, which has always liked to blow up the circle, made its world debut with the first new car of 2022 - mercedes-Benz VISION EQXX concept car. Yes, you read that right, Mercedes-Benz gave the opportunity to enlighten 2022 and define the future of pure electric luxury to a concept car, in the name of EQ, XX.
Let's take a look at a set of beautiful pictures to feel it!
Let's take a look at a set of core data to feel!
Wind resistance coefficient of 0.17
95% ultra-high energy efficiency
Less than 10 kWh of energy consumption per 100 km/ h
Close to 100 kWh battery pack
Cruising range of more than 1000 km
Battery energy density close to 400 Wh/L
The maximum system voltage exceeds 900 volts
To be honest, when I read EQXX's 15,000-word product information, the only thought in my heart was to worship, sighing "your uncle or your uncle", Mercedes-Benz is Mercedes-Benz. When self-righteous "insiders" still hold the data of EQC and EQA and ridicule Mercedes-Benz for turning too slowly on the road of electrification transformation, Mercedes-Benz uses this EQXX that took only 18 months to develop and slap their faces, which hurts. And when I calm down and summarize carefully, I still feel that the content that can be said on EQXX is really too much, and I am depressed that I can't put the 26 pages of product information and disks out, so I want to peek at the leopard through the following 3 keywords, hoping to see it.
Keywords: energy efficiency
The most energy efficient in Mercedes-Benz history
EQXX emphasizes energy efficiency in every hair from head to toe, from inside to outside. What is visible to the naked eye is that when most fuel vehicles are still talking about 39% and 40% thermal efficiency, and when the energy efficiency of mainstream electric vehicles is still hovering at 75%, the EQXX lightweight and efficient electric drivetrain will eventually transfer 95% of the battery energy directly to the wheels. As a result, EQXX has an amazingly low energy performance, its energy consumption per 100 km is less than 10 kWh, and with a battery pack of nearly 100 kWh, the range is more than 1000 km.
Leading such as Mercedes-Benz, in the attitude of energy efficiency and endurance, obviously disdain to use such a "simple and crude" method as increasing the size and weight of the battery, but give "innovative transmission system + increase battery energy density + improve aerodynamics" and other multi-dimensional solutions to obtain higher energy efficiency and longer battery life.
The EQXX's drivetrain was redesigned by Mercedes-Benz and has an energy efficiency of 95%. With an output of 150 kW, EQXX's electric drivetrain, which includes batteries, electric drives, wheels, etc., is a world-class electric drivetrain that integrates energy efficiency, energy density and lightweight engineering. The electric drive is a dedicated unit consisting of an electric motor, transmission and power electronics (using a new generation of silicon carbide) with a power electronics unit based on the upcoming Mercedes-AMG Project ONE supercar design.
On the battery, Mercedes-Benz has developed a new battery pack specifically for EQXX, through the development ideas and professional mechanical design of formula 1 racing cars, through advanced anode chemistry and highly integrated battery pack, to achieve an amazing energy density of nearly 400Wh/L, and the battery volume is only 50% of the new EQS, and the weight is 30% lighter, this figure makes the EQXX compact size can accommodate a battery pack with a usable energy of slightly less than 100 kWh, The total weight of the battery is only 495 kg. Here Mercedes-Benz replaced a concept, conventional we like to use Wh / L when the mobile phone battery, and in the car we like to use Wh / kg of the unit of calculation, if calculated according to the 100 kWh battery pack, then the energy density of EQXX is about 202Wh / kg, which is also very outstanding.
In terms of aerodynamics, the wind resistance of EQXX can be 0.17, and it should be known that the EQS with a wind resistance coefficient of 0.20 that we tested a while ago is already a ceiling-like existence in the industry. As we all know, in long-distance driving, nearly two-thirds of the power of ordinary electric vehicles is used to overcome air resistance, and reducing the wind resistance coefficient of 0.01 can increase the cruising range by about 2.5%. To get lower wind resistance, EQXX does a lot. For example, ultra-smooth designs, such as retractable rear diffusers, such as the front face that is smaller than the CLA four-door coupe, such as the active grille with "smart air curtain", such as the air outlet position located on the hood, such as the rear wheelbase is 50mm smaller than the front wheelbase, such as the cooling version installed on the bottom of the car, and then the tires that apply ultra-low rolling resistance and aerodynamic optimization... Aesthetics and functionality have always been the two most difficult to balance dimensions in the eyes of designers, and it is incredible that EQXX can hold the lowest wind resistance in history while having such elegant lines!
In short, in the eyes of Mercedes-Benz, energy efficiency is the new "hard currency". It is unimaginable that in order to achieve more energy efficiency, Mercedes-Benz even does not spare the sound, they even reduce the sound energy consumption by improving the interior surface to reduce the absorption and rebound of sound waves - it is simply useless!
Keywords: sustainable
Interpret avant-garde luxury
In mercedes-benz's concept, high efficiency means not only less energy consumption for longer endurance, but also effectively reducing the impact on nature while providing luxury and convenience at your fingertips, and achieving a balanced interaction between man and nature with lightweight materials with minimal environmental footprint. Just a few examples.
On the roof of the EQXX there is an ultra-thin solar panel that stores electrical energy in a lightweight lithium iron phosphate battery to power climate blowers, lights, infotainment systems and other auxiliary equipment to reduce energy consumption and increase range. In a single day and under ideal conditions, the system can increase the mileage of long-distance travel by 25 kilometers.
In the EQXX battery design, the battery cover is made of a unique sustainable composite material taken from sugarcane waste and reinforced with carbon fiber, the same material used in Formula 1 racing, making excellent results in the lightweighting of the battery.
The application principle of interior materials in EQXX is "to create maximum comfort and style with the lightest weight, and to refuse to use any animal products". The door handles are made of biodegradable pure plant silk; the seats are made of two outstanding leather alternatives – made from cactus raw material (a combination of cactus powder fibres and a sustainable bio-based polyurethane matrix) and mycelium (the root structure of mushrooms), carpets are woven from 100% bamboo fibers, glossy fabrics for floor and door trims are derived from recycled PET bottles, and Dinamica materials containing 38% recycled PET are applied to the roof The interior and rear window castings are made of UBQ materials made from waste recycled from home and municipal landfills, which is a sustainable plastic alternative that is environmentally friendly and reduces the weight of components by 15%-20%.
All of the above shows not only the sustainable concept of Mercedes-Benz, but also their courage and confidence to break the norms, make a bold move, and dare to adopt new ideas to interpret the pioneer luxury of the electric era.
Keyword: integration
Global resources are at my disposal
As Schöfming, member of the board of directors and chief technology officer of Daimler AG and Mercedes-Benz AG, said: "The meaning of the VISION EQXX concept car suffix XX is: the first X represents X-factor, that is, the conventional thinking beyond electric mobility, and the second X represents X-divisional, that is, the use of a rapid cross-departmental collaborative development approach to strengthen the Mercedes-Benz brand power. By integrating the industry-leading knowledge of global partner companies, start-ups and institutions, and adopting highly advanced digital tools, mercedes-Benz AG will be enhanced in the breadth and depth of its development capabilities. ”
For example, the EQXX's efficient and compact electric drivetrain and new battery pack were developed in collaboration with Mercedes-AMG High Performance Powertrain GmbH, while the lightweight battery cover was designed in conjunction with the chassis partners of the Mercedes-Benz Grand Prix racing team.
For example, EQXX's solar panels were developed in collaboration with the Fraunhofer Institute for Solar Systems, Europe's largest solar energy research institute.
For example, EQXX's tires are Turanza Eco tires in collaboration with Bridgestone, which combine lightweight and environmentally friendly ENLITEN and Ologic technologies to achieve ultra-low rolling resistance.
For example, the material for EQXX door handles is biosteel fibers produced by AMsilk, the inventor of bionic fibers.
For example, the UBQ material used at the interface between the EQXX interior and rear window castings is produced by UBQ Materials, an Israeli startup.
For example, EQXX's springs, an innovative plastic leaf spring developed in collaboration with a startup at the University of Darmstadt and Rheinmetall, are lighter than traditional coil springs.
For example, EQXX's innovative neuromorphic computing car machine system was developed with a hardware and software system based on Akida's neuromorphic system-on-chip from BrainChip, a leading artificial intelligence company in California, which can make "Hello, Mercedes-Benz" wake up 5-10 times faster than traditional voice control. At the same time, the self-driving assistant was developed in cooperation with Sonantic's speech synthesis experts, making the "Hello, Mercedes-Benz" mind-reading voice assistant more emotional and expressive, and the sound effects are more realistic.
For example, EQXX's navigation, developed in collaboration with navigation specialist NAVIS-AMS, is the first 3D real-time navigation system compatible with this size of screen, supporting seamless zoom and scrolling, and in 3D city views, the satellite screen can be enlarged to a height of 10 meters.
See how strong this multidisciplinary team of departments is, driven by software to develop advanced and efficient solutions with great business potential for the future. The phrase "let professional people do professional things" is perfectly reflected in Ben EQXX, and this is why it only takes 18 months for EQXX to start from scratch to the landing of the whole vehicle.
Write at the end
Mercedes-Benz is Mercedes-Benz, with its as always arrogant and domineering pointed out a future pure electric luxury road, although, we clearly know in our hearts that EQXX as a concept car and our lives are far away, but, predictably, it is a direction, a tinder, guiding the future, riding the wind and waves, breaking through boundaries, opening up new channels. And we are also deeply looking forward to the installation and presentation of its unprecedented advanced technology on the subsequent mass-produced Mercedes-Benz models. As Conlinson, Chairman of the Board of Directors of Daimler AG and Mercedes-Benz AG, put it – Mercedes-Benz's vision is to build the world's most desirable electric vehicle.
