Yesterday (January 4), the Mercedes-Benz VISION EQXX concept car officially ushered in the world premiere. The wind resistance coefficient is as low as 0.17, and the mileage of a single charge is more than 1000 kilometers, which alone is enough to say it all. In the current era when new energy vehicles tend to be homogeneous in design, the VISION EQXX concept car allows us to see the answer sheet handed over by Mercedes-Benz in the face of the future.
"The VISION EQXX Concept car perfectly illustrates our vision for the future of electric vehicles. The project, which just started 18 months ago, has become mercedes-Benz's most energy efficient model ever: it consumes less than 10 kWh per 100 km/ 100 km and has a range of more than 1,000 km on a single charge," said Ola K llenius, Chairman of the Board of Directors of Daimler AG and Mercedes-Benz AG. Its futuristic shape is breathtaking, underscoring the company's vision to build the world's most popular electric car. ”
Although Conlinson's words are still as official, I have to agree that the VISION EQXX concept car is indeed a futuristic electric car. Hopefully, Mercedes-Benz will be able to mass-produce it, just as it is now. After all, in the history of Mercedes-Benz, there are many models such as SLR and SLK, and production cars and concept cars are very close. Moreover, according to the pictures, it is not difficult to find that the VISION EQXX concept car has completed the wind tunnel test, which means that it is not just a sample, and the probability of Mercedes-Benz mass production is still very large.
Let's take a look at what the VISION EQXX concept car has. On December 17 last year, Mercedes-Benz introduced the new EQS. According to the data, the new EQS has the optimal drag coefficient of 0.20 for the production car, and the VISION EQXX concept car takes this step further. To better blend passive and active aerodynamics, Mercedes-Benz engineers used advanced digital modeling techniques, which also reduced the time required to build traditional clay models.
Generally speaking, for a brand new concept car, it often takes 1 to 2 years or even longer in terms of exterior design, but the VISION EQXX concept car only takes less than half a year to determine the appearance. With a more streamlined design process and digital tools, the styling time of the whole vehicle is shorter. The teardrop-type bodywork, active intake grille, concealed door handles, and long-tail streamlined design all reduce wind resistance. The final VISION EQXX concept car achieves an ultra-low drag coefficient of 0.17.
In fact, the design of the VISION EQXX concept car was inspired by the IAA aerodynamic concept car Concept IAA released by Mercedes-Benz in 2015. IAA is also the first Mercedes-Benz model to widely adopt active aerodynamic performance, and its birth basically establishes the future research and development direction of Mercedes-Benz in aerodynamics, which is a milestone. The VISION EQXX concept car was developed at the IAA.
Through the pictures, we can see that inside the VISION EQXX concept car, the new car is equipped with the brand's first fully seamless 47.5-inch ultra-thin all-in-one screen, and introduces a game engine and a fully optimized user interface. The R&D team has cooperated across borders to jointly develop the first 3D real-time navigation system that is compatible with this size screen, which can enlarge the satellite screen to a height of 10 meters in the 3D city view, and the sense of science and technology is "full".
At the same time, thanks to the new electric drive system developed in-house, the VISION EQXX concept car achieves efficient use of energy, compared to the most efficient internal combustion engine drive system can only achieve 30% energy efficiency, its lightweight and efficient electric drive system will eventually transmit up to 95% of the battery energy directly to the wheels. In addition, the "Energy Efficiency Assistant System" also helps to improve driving efficiency, which 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.
Not only that, Mercedes-AMG High Performance PowerTrain Co., Ltd. has developed a new battery pack for the VISION EQXX concept car, 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 energy density of close to 400 Watt Hours / liter, its battery volume is only 50% of the new EQS, and the weight is reduced by 30%. This allows the VISION EQXX Concept to accommodate a battery pack with a usable energy of nearly 100 kWh in its compact size.
It is worth mentioning that the VISION EQXX concept car also uses a large number of sustainable materials. Take inspiration from organic forms such as fungi, pure plant silk, and avoid animal products. These sustainable, innovative, high-performance materials are expected to replace the oil and animal products that are now widely used in the automotive industry in the future. Futuristic luxury design that balances man and nature points the way forward.
In summary, in the VISION EQXX concept car, I see Mercedes-Benz's attitude towards the future of pure electric cars. Finally, I sincerely hope that Mercedes-Benz will mass-produce the VISION EQXX concept car as soon as possible, and our era needs its existence.
