In view of the background of electrification, various new forces have sprung up one after another, and their forward-looking thinking and radical attitude have risen up and threatened to set off a subversive revolution in the history of the automobile industry a hundred years later. At this time, the traditional factories of the older generation seem to have been inexplicably labeled as "not thinking of making progress" and "self-appointed".
Is this really the case? As a well-deserved benchmark in the luxury field for a hundred years, Mercedes-Benz has released the "C· A· S· E)" strategy, the electrification layout to the world, to 2019 to launch the first model of the EQ family EQC, and then to september 2021 IAA Munich Motor Show with a huge pure electric concept car camp debut, for the electrification innovation, Mercedes-Benz every step of the action is not a quick, but the shot is the trump card. The concept car of VISION EQXX, which was announced shortly before the end of the year, has finally officially unveiled the mystery.
With mass production as the goal, we will define the future mobility era with a new technology blueprint
If EQS is regarded as the integrator of forward-looking technology applications in the current stage of Mercedes-Benz's electrification era, then the VISION EQXX concept car from the cutting-edge power system, to lightweight engineering technology, to a large number of recyclable materials, it is more to show the call and leadership of the future travel era.
Endurance and energy consumption are the two important topics for thinking about the VISION EQXX concept car. The station is located in the design angle to solve the endurance and energy consumption, the most direct and effective means is to change the wind resistance coefficient of the vehicle and the use of body materials. Unlike Mercedes-Benz, which has released various mass-produced new cars in the past, vision EQXX has carried out a very forward-looking interpretation and expression from the styling design.
VISION EQXX to "sensuality and purity" as a luxury aesthetic design concept, giving the entire body ultra-smooth styling characteristics, with ultra-low rolling resistance and aerodynamic optimization of the tire, so that it has a drag coefficient as low as 0.17, you know, rugby wind resistance is only between 0.18-0.2, ordinary adults are 0.8-1.2, and flagship mass production model EQS is 0.20.
The vision EQXX's entire body line is full of tension, and the low center of gravity of the front of the front of the car plus the iconic through-feed pullback standard LED headlight set gives the body a very significant low-lying posture, which is very aggressive. Under the light group is a closed design, the "three-pronged star" logo is covered with surfaces, at the same time, a narrow active air inlet is also designed under the front bumper, and connected to the two square inlets above the front cover, when the vehicle's electric drive system requires high light heat dissipation, the air intake will actively open, and the wind resistance coefficient will only increase by 0.007.
The design of the side and rear is the essence of vision EQXX to convey the premise of "endurance and energy consumption". From a top-down perspective, the vision EQXX's roof is like a smooth greenhouse dome, flowing to the rear of the car in the form of water droplets, and when the retractable rear diffuser is retracted, it can be seamlessly integrated into the body, showing a full elegance, of course, this design also takes into account the reduction of the wind resistance coefficient.
Compared with the exterior design, the vision EQXX interior mainly adopts a simple and beautiful lightweight design, and a large number of sustainable lightweight materials are added, which ensures the luxury and comfort of the vehicle while giving the vehicle a zero-emission future. The interior door handles are made of biodegradable pure plant silk, the seats are made of cactus raw materials and mycelium, and the carpet is woven with 100% silk fiber. The interior of this new design concept, with the gift of nature, points out the way forward for the future luxury design that balances man and nature.
In addition, the VISION EQXX is equipped with Mercedes-Benz's first 47.5-inch seamless through-screen. Unlike the one-piece screen currently on the market, the R&D team of the screen has ported the game engine and the user interface that can be fully optimized internally through cross-border cooperation, and developed a 3D real-time navigation system that is compatible with the screen, which can enlarge the satellite screen to a height of 10 meters, thereby further refining the ground information.
The pursuit of battery life, but also the pursuit of energy efficiency
The pursuit of long endurance of pure electric models has always been the unremitting goal of major car companies, from 400 kilometers to 600 kilometers, and now individual models have exceeded 1000 kilometers, we see that the mileage of pure electric models is constantly refreshing the upper limit.
However, the long battery life conditions of vision EQXX are different from the simple practice of other models by equipping large-capacity batteries, it is through the thinking of energy efficiency and battery life, on the one hand, with the help of a new self-developed electric drive system, to achieve efficient use of energy; on the other hand, through the AMG department for vision EQXX developed a new battery pack, through advanced anode chemical process, to achieve a battery energy density of only 400 watts / liter, The volume and mass are only 50% and 70% of EQS.
With the joint blessing of dual technology, vision EQXX consumes less than 10 kWh per 100 km/ 100 km/ 10 km/ 100 km/ 100 km/ 10 kWh. What is this concept? Converted into gasoline consumption, it is equivalent to consuming 1 liter of fuel per 100 kilometers.
It is worth mentioning that the power system that powers many auxiliary equipment of VISION EQXX is not directly provided by the power battery, but obtains additional energy from the 117 solar cells on the roof, and through the energy consumption of the high-voltage system, the result is an increase in the mileage. Under single-day or ideal conditions, the solar cell system can add an additional 25 kilometers to the long-distance range.
At the same time, vision EQXX is equipped with an "energy efficiency assistant system" that also helps to improve driving efficiency, which can give the driver the most efficient driving advice based on information such as energy flow, terrain, electricity, and even the direction and intensity of wind and sun.
At present, many of the functions applied in the VISION EQXX concept car have been applied to the production car, and more advanced technologies will be installed in subsequent production models. With this energy-efficient model in the history of the Mercedes-Benz brand, vision EQXX has once again revolutionized the fundamentals of electric mobility, redefining the way individuals travel and striding on the road to building the world's most desirable electric vehicle.
