How much of a new energy electric vehicle market is rolled up, just look at Mercedes-Benz cars. While there are still people in the circle of friends patiently interpreting the Mercedes-Benz EQS, the news of the world premiere of the Mercedes-Benz VISION EQXX concept car began to carpet bomb again.
This concept car not only attracts attention with the ultra-low drag coefficient of 0.17Cd, but is also officially called the most energy-efficient model in the history of the Mercedes-Benz brand. With this kind of thing at the beginning of 2022, can everyone not be curious about this new car?
So I and netizens have questions:
What is the purpose of Mercedes-Benz hyping up this concept car that landed in 18 months?
What's so special about this concept car?
Isn't the Mercedes-Benz EQS the "optimal solution" for Mercedes-Benz electrification?
Today, pin play / pin driving for everyone to analyze and see.
Read the ultra-low drag coefficient of 0.17 with the design
As new energy electric vehicles gradually enter the main stage of car company competition, automotive designers have also begun to think about new ideas for the design of new energy electric vehicles. After there is no restriction on large parts such as engines, what design innovations can new energy electric vehicles have, and even changes in design ideas?
When the Mercedes-Benz EQS was launched, some people realized that shortening the front and rear suspensions, having a long driving space, and cars with coupe design styles would become the mainstream design ideas of new energy electric cars.
However, mercedes-benz EQS in the market has not yet sat hot, Mercedes-Benz began to look for new answers, vision EQXX concept car not only added a closed front face, but also designed a long rear. This can be seen in the shadow of the Mercedes-Benz Concept IAA concept car of that year.
However, in addition to an improved version of the Mercedes-Benz Concept IAA concept car, I think the Mercedes-Benz VISION EQXX concept car is also like the NASCAR racing car in the United States.
But then again, the Mercedes-Benz VISION EQXX concept car, no matter who it looks like, is designed to be like a "raindrop" because it has to achieve ultra-low wind resistance.
People who know the design of the car know that the known raindrop shape is the smallest wind resistance coefficient, about 0.05Cd, and the Mercedes-Benz VISION EQXX concept car also does this in order to achieve ultra-low wind resistance of 0.17Cd.
The combination of "front circle rear" and "long tail" is also to reduce the resistance of the windward surface, so that the negative pressure area of the rear of the Mercedes-Benz VISION EQXX concept car is far away from the rear of the car, reducing the turbulence at the rear.
At the same time, the closed front face, the low wind resistance wheel hub, and the retractable rear diffuser at the rear of the car are all small helpers to help it reduce wind resistance.
But although the Mercedes-Benz VISION EQXX concept car has reached an ultra-low wind resistance of 0.17Cd, this is not surprising.
Because our own brand GAC Aean also released a concept car, called EN0.146, which can achieve ultra-low wind resistance of 0,146Cd, which is 2 years earlier than the Mercedes-Benz VISION EQXX concept car. Therefore, some people on the Internet call the Wind Resistance Coefficient of the Mercedes-Benz VISION EQXX Concept Car "the lowest in history", which is indeed somewhat underconsidered.
At a time when consumers are paying more attention to appearance, some people think that this car is not good-looking. The "sensual and pure" design language created by the designers of the Mercedes-Benz VISION EQXX concept car has not been fully recognized.
I've heard the sound of "the front face is not as good as the rear design"; I've heard people say that the driving space is too low, and the rear seating space looks very small; and even some people around me think that its front face is a bit like a combination of xiaopeng P5 and future K50...
These "sounds" must have a certain reason, and they are not empty. But no matter how good it looks, or how low the drag coefficient is, how much design is retained after mass production, and whether the drag coefficient of the mass production model is equally low is unknown.
A concept car is a concept car, and there is still a long process between it and mass production. Regulations, manufacturing costs, raw materials, supply chains, etc., are all necessary factors that restrict and hinder its mass production. We can only "wait for the good news".
For the interior materials, will Mercedes grow mushrooms?
The design of the interior of the Mercedes-Benz VISION EQXX concept car is actually obvious, the 47.5-inch ultra-thin integrated screen and narrower central armrest channel are quite different from the previous models. Similar to the steering wheel of the AMG, the turbo air outlet, etc. are all continuations of the characteristics of past models.
Compared with the styling design, the materials used in the interior of the Mercedes-Benz VISION EQXX concept car are the most worth talking about. In order to achieve the design concept of "man and nature", the designer has done his homework in the use of materials.
The Mercedes-Benz VISION EQXX Concept car has a biodegradable pure plant silk handle on the inside of the door, and the carpet is woven with 100% bamboo fiber.
Most notably, the seat fabric is made of cactus raw material and mycelium, which is said to achieve the same texture and touch as leather, but can replace animal leather.
Seeing this, I can't help but ask, if these materials need to be mass-produced, is Mercedes-Benz hiring someone to start growing cacti and vegetable mushrooms? Although this is a joke, I want to express the pain points of the high cost of mass production of these materials and the problem of supply chain support.
In fact, natural materials and environmentally friendly materials have always been the focus of designers, not much new. Even the domestic mobile phone realme uses biological materials made of pulp to make a mobile phone backplane, and a brand as large as Mercedes-Benz can understand the use of cactus and mycelium as seats.
However, we should indeed appreciate and recognize mercedes-benz-like companies for integrating "nature" into product design, which is undoubtedly a good thing.
But how to achieve mass production of these concepts, how to do reliability, durability, and how to reduce the cost of car purchase for consumers, these are worthy of our attention.
How to achieve pure electricity 1000km endurance
As a pure electric concept car, the Mercedes-Benz VISION EQXX also values its endurance. The energy consumption of 100 kilometers is less than 10 kWh, and the range of a single charge after digital simulation of real road conditions exceeds 1000 kilometers, which has become one of the focuses of discussion in the industry.
At present, there are not many models that can achieve a pure electric range of 1000km, which is completely different from the concept of 1000km endurance of those extended range electric vehicles. However, the move of the Mercedes-Benz VISION EQXX concept car is not out of reach, and the NIO ET7 and GAC Aean LX Plus also said that the comprehensive endurance exceeded 1000km.
In any case, the Mercedes-Benz VISION EQXX concept car has really wasted a lot of effort in order to achieve such endurance performance, not only using new energy vehicle research and development personnel, but also borrowing AMG and F1 professional technical teams to escort its driving performance.
From the existing information, I summarized the reasons why the VISION EQXX concept car has a battery life of more than 1000km into three points:
New battery + solar
To meet the endurance requirements, Mercedes-AMG High Performance Powertrain has developed a new battery pack for the VISION EQXX concept car.
It is reported that the battery pack volume is only 50% of the Mercedes-Benz EQS, the weight is reduced by 30%, with an energy density of nearly 400 watt-hours / liter, and the Mercedes-Benz VISION EQXX concept car put down a battery pack of nearly 100 kWh.
At the same time, Mercedes-Benz has also optimized the new electric drive system developed by itself, coupled with the "energy efficiency assistant system", so that this new concept car can directly transfer 95% of the battery energy of the electric drivetrain to the wheels, and finally achieve energy consumption performance of less than 10 kWh per 100 kilometers.
In addition, the roof of the VISION EQXX concept car also uses a large solar charging panel, which absorbs the light energy stored by an independent lithium iron phosphate battery, which can also release 25km of additional battery life in addition to powering the interior lights, entertainment and air conditioning systems.
Ultra-low wind resistance
During the driving process, the faster the speed of the car, the greater the relationship affected by wind resistance. If the speed rises to 60km/h, almost 60% of the power is used to overcome wind resistance. Therefore, wind resistance has a great impact on the acceleration performance and endurance of the vehicle.
In the case of high-speed driving of electric vehicles, for every 0.01Cd reduction in the wind resistance coefficient, the cruising range can be increased by more than 10 kilometers compared with the original, which shows that reducing wind resistance is the key point to ensure the endurance of electric vehicles.
Mercedes-Benz VISION EQXX concept car through the styling design to achieve 0.17Cd ultra-low wind resistance is indeed remarkable, to know that most cars are above 0.20Cd, which is also one of the important factors that can achieve 1000km endurance.
Lightweight design
Weight loss is not only the pursuit of racing cars, new energy electric vehicles are also particularly needed. The weight reduction of the battery pack, the weight reduction of the body material, the weight reduction of the configuration, etc., are the directions that designers have been working towards.
The Mercedes-Benz VISION EQXX concept car has a lot of lightweight design. Sustainable materials for interiors are used to replace heavier metals and leathers. Door handles and seat materials are also making efforts to reduce weight.
At the same time, the carbon fiber material and the lightweight F1 subframe chassis are added to reduce the concept car's weight to 1750kg. This is also a great help for its endurance performance.
Other things to watch
In addition to the 0.17Cd ultra-low wind resistance, the new battery pack and the new interior materials, mercedes-Benz engineers have also optimized the intelligent interconnection system of the car. They employ an innovative information processing method called neuromorphic computing that greatly reduces energy consumption and increases the wake-up speed of "Hello, Mercedes- Benz" to 5-10 times faster than traditional voice control functions. The Mercedes-Benz Nebula Assistant is also smarter and can take care of the needs of every passenger.
The "Energy Efficiency Assistant System" equipped with the Mercedes-Benz VISION EQXX concept is also a new idea to improve driving efficiency. It can give the most efficient driving recommendations based on information such as energy flow, terrain, electricity, and even the direction and intensity of wind and sun. This is also one of the best ways to ensure endurance.
Write at the end:
The release of the Mercedes-Benz VISION EQXX concept car is enough for everyone to discuss. However, although the design of this concept car is more exaggerated than that of EQS, its appearance is not exciting enough for the design of new energy electric vehicles.
Some people say that the Mercedes-Benz VISION EQXX is not good-looking, and I myself do not understand how the "luxury" referred to by the Mercedes-Benz brand is displayed in the concept car. If changing the interior material is luxury, there are too many materials that can be used.
Or rather, the Concept of the Mercedes-Benz VISION EQXX concept is not here. For new energy electric vehicles, the Mercedes-Benz VISION EQXX concept car has indeed improved compared with now, and compared with the mercedes-benz cars of the past, it is indeed the best energy efficiency model.
However, in terms of technology and user experience, the Mercedes-Benz VISION EQXX concept car has not made revolutionary progress. The wheel hub motor was not applied, the suspension system that was more comfortable than the Mercedes-Benz "magic carpet" was not shown, and the Mercedes-Benz VISION EQXX was still a small step forward in the existing technology.
But even if I poured cold water on the concept car of Mercedes-Benz today, in the traditional car brand, the strength of Mercedes-Benz is still obvious, and from EQS we can see the ability and speed of big brands in creating new things.
However, we consumers expect Mercedes-Benz to fully surpass the new forces of car manufacturing and give us a new definition of electric vehicles. At the same time, we also hope that Mercedes-Benz will let us see the hard-core technology that new energy electric vehicles should have in the future, and this "hardcore" is even better if it is still unknown.
