[Understand the original 2021 Guangzhou Auto Show] On November 17, on the eve of the 2021 Guangzhou Auto Show, Audi released a new GrandSphere concept car in China. The car will position pure electric luxury cars and will become a revolutionary product of the Audi brand.
As a new car for 2025, it will support L4 -level autonomous driving technology. In the autonomous driving mode, the car will be switched to a wide space, without steering wheels, pedals and instrument panels. lounge”.
Positioning pure electric luxury car length super A8L
In terms of size, the Audi GrandSphere concept is 5.35 meters, a width of 2 meters, a height of 1.39 meters, and a 3.19 -meter wheelbase has exceeded the extended version of the Audi A8L. Internal space. The overall body line of the car is relatively concise. It uses the “compact four -door GT” shape design to enhance the visual impact.
On the front part, the new car is bold and new. It adopts a flattering hexagonal integrated grille to highlight the family identity. The grille is covered by a transparent cover. The internal light group can be lit when driving.
The headlights on both sides are quite “bionic” style. The rings after lighting are similar to the eyes of consequences, and can adjust the size of the lighting area according to the daytime running lights or dynamic segmented indicators.
On the side of the body, the Audi GrandSphere meets the specific structure requirements of the electrical drive system. It uses a short front suspension, a flat front cabin cover, and a large forward windshield that is highly protruding forward. Behind the wide C -pillar, the rear of the car adopts a classic streamlined design. At the same time, the dynamic tilt arched design of the roof has allowed the Audi GrandSphere concept car to continue the tradition of the Audi Sportback model.
At the same time, the concept car also uses an exaggerated 23 -inch double -six -spoke wheel, similar to the taillights to the headlight group. Although the exhaust system is no longer needed, the car still uses exaggerated decoration.
2+2 seats layout for home
Static or autonomous driving state can be stored in the steering wheel
The interior design is very “advanced”. Before turning on the driving function, the black screen of the steering wheel virtual instrument system will be hidden. The car shows a very home rest atmosphere, providing a 2+2 seat layout. At the same time, its interior decoration and materials are stronger and sustainable and reused. The inside of the car, seat sleeves and carpets are made of wood, wool, synthetic textile fabrics and metal materials, which are comfortable to touch. Many of the materials are made of sustainable or reuse raw materials, such as wooden leather veneer; the whole vehicle does not use leather materials.
The car is decorated with sustainable or reused materials
In the driving mode, the flat -bottom steering wheel will pop up
After starting the vehicle, projection will appear on the wooden platform below the front block. Depending on the driving mode, such as the driving mode of the steering wheel or the L4 autonomous driving mode, the projection may be distributed in the entire car, or it is displayed in front of the driver or the co -pilot. Through this display, the driver can query all the information required for the driver.
The steering wheel and pedal can be hidden in the L4 autonomous driving mode
Back row is spacious and comfortable
At the same time, the comfort performance has also undergone fundamental changes: the “noble” of traditional luxury cars is located in the rear row, and in this car, the “first class” experience is moved to the front row, because the front row space will not not be in front of the row space, which will not not be the front space. Due to the limitations of driving functions and control components. In the L4 autonomous driving mode, the steering wheel and the pedal will be hidden. The front area of the car will become a free space throughout the width. Through large -scale front windows and side windows, it can have a wide field of vision.
The angle of the front seat can be adjusted and wider
In the state of standing upright, the driver can drive the Audi GrandSphere concept car in an ergonomic posture without using the L4 -level autonomous driving function. When the back is leaning 40 degrees, passengers can easily use the information entertainment system. If the back is tilted to 60 degrees, the best rest can be achieved. At the same time, the top of the back can be tilted 15 degrees forward as the headrest. Integrated in this area with air outlets and speakers with filtration and temperature adjustment functions, which can play private voice that other passengers cannot hear.
Below the metal panel between the front seats, a compact car refrigerator is set with two glass and beverage bottles. This also represents the pursuit of the first -class comfort of the Audi GrandSphere concept car.
Functions such as eye tracking, gesture or voice control, handwriting input and touch can be used in all operating modes. The Audi GrandSphere concept car can understand their preferences and common menu according to the needs of different users. On this basis, vehicles can not only intelligently complete the basic commands, but also provide advice to users.
You can also experience more entertainment functions such as VR and other entertainment functions
In addition, the door armrests are also integrated with control panels. Therefore, the vehicle can always provide passengers with a touch screen with visual information and display its position through optical indicators. At the same time, there are VR glasses on both sides of the left and right door armrests, which can be used with information and entertainment systems, such as the Holoride system.
Support 800 volt charging technology battery life exceeding 750 kilometers
Great battery life over 750 kilometers
The Audi GrandSphere concept car is based on the PPE platform, with a battery module capacity of 120 kWh. Because Audi uses an overall body bottom plate between the axis, the battery module can use a flat layout. The vehicle is equipped with the Quattro four -wheel drive system that is vital to the Four Ring brands. A motor is equipped on the front and rear bridges.
The total output power of the two motors is 530 kilowatts, and the torque can reach 960 N · m
The core of the car driving system is 800 volt charging technology. Like the previous Audi E-TRON GT, thanks to this technology, the DC charging power of the vehicle can reach up to 270 kilowatts, and the battery can complete the charging in as short as possible.
The charging time is as fast as the traditional fuel vehicle. Only for ten minutes to charge the vehicle can increase the mileage of more than 300 kilometers. In 25 minutes, 120 kWh of batteries can be charged from 5%to 80%.
at the same time,
The maximum of the car can have a range of more than 750 kilometers, and the acceleration time of 100 kilometers is more than 4 seconds.
In terms of battery life and charging speed, it maintains the same level as traditional fuel vehicles.
Equipped with dual motor
Its front axle adopts a five -link suspension structure that is optimized for electric vehicles. The rear axis is made of multi -link structure, and it is made of aluminum alloy like the front axle. Although the wheelbase is long, the rear axle with a steering function can still ensure excellent handling. As a luxury travel car, the Audi GrandSphere concept car adopts
Single -chamber air suspension system with adaptive damping control
Essence Fully meet the needs of dynamic driving, and in a stable driving state, it can ensure good comfort and avoid obvious center of gravity offset.
Audi GrandSphere concept car is still equipped
Active suspension system
Through the motor actuator, each wheel is highly controlled by each wheel in a few milliseconds. Thanks to this, no matter what kind of driving conditions, the body status can be adjusted actively, thereby greatly reducing the body’s roll and pitch under acceleration or braking. Because the front camera has a bumpy road condition recognition function, the body can be proactively controlled. In addition, the terrain data of the navigation system, including the radius, slope, and slope of the navigation system, will be included in the system prediction.
Considering that the Audi GrandSphere concept car production version will not be launched until 2025. The L4 -level autonomous driving technology equipped is also “quite advanced”. It is still difficult to judge which competitors will this model encounter. If it is judged by the current car market, the potential competitors of the car may be Mercedes -Benz EQS and the flagship pure electric sedan of the BMW i7 that may be launched in the future.
