Powerful design language: breakthrough increase in body width?
Audi e-tron family S models adopt Audi family design language, and the front bumper and rear bumper have clear and sharp contours, and the diffuser width is almost the same as the car width. The side air curtain of the bumper extends wider and higher under the headlights, which effectively improves the air flow. The wheel arches on both sides of the vehicle are wider than before? 23? Millimeter. Silver elements are used at the front bumper edge, single grille and door, which enhances the high-end features of the vehicle. Audi can also spray contrast colors for larger detachable parts according to customer requirements.
These two Audi e-tron? S-series models can be equipped with digital matrix LED, which is used in mass production models for the first time in the world. Headlights, the light scattered into tiny pixels can be controlled with high precision. This design takes into account many new functions, such as lane lights and direction lights. In a narrow area, the position of the vehicle in the lane can be displayed to help the driver keep the center position for safe passage.
Audi's e-tron family S models will maintain a dark interior design, and a wide arc will connect the display screen of the virtual exterior rearview mirror with the top cover above the Audi virtual cockpit. The instrument panel is designed with the driver as the center, and the center console is connected with the open central armrest. The electric adjustable sports seat adopts leather /Alcantara chair cover, the shift lever is embossed with diamond S, and the threshold and steering wheel are equipped with S? Signs; emblem
Driving experience upgrade: the first batch of electric vehicles equipped with three-motor drive system
The new Audi e-tron S and the new Audi e-tron? s？ Sportback adopts the same level of power configuration, and adopts a motor layout in which two motors are installed on the rear axle and one motor is installed on the front axle. It is the world's first electric vehicle equipped with a three-motor drive system.
The driving layout is based on the principle of modular structure. Audi e-tron? A more powerful motor has been installed on the front axle of two S series models. Is the motor Audi? Electronic creation? The 55-year-old rear axle provides electricity. After the improvement of adaptive design, the power is 124 kW, and the boost power can reach 150 kW. Two identical small motors are installed on the rear axle, which are completely matched. Comprehensive power 196 kW, and boost power can reach 264 kW.
The maximum output power of the system is 320 kW and the maximum torque is 808 Nm. When "boost" is started by shifting S gear or selecting "dynamic" driving mode, the maximum output power and torque can reach 370 kW and 973 Nm respectively. At the same time, the two models can accelerate from standstill to 100 km/h in 4.5 seconds, and the maximum speed of electronic limit is 2 10? Kilometers per hour. Under the WLTP test, the cruising range of the two models can reach 360km and 365km respectively after being fully charged.
Audi's quattro？ Pioneering innovation: dual-motor electric torque vector control
Audi e-tron? The starting system of S model also adds the function of electric torque vector control. The dual motors of rear drive will not be controlled by mechanical differential, but will directly transfer the driving force to the wheels through the transmission device, which will make driving more agile, improve automatic steering performance, improve turning speed and enhance driving pleasure.
In normal driving mode, just start the rear drive motor. When the drive system needs more power, the front drive motor will automatically turn on, and the power will be seamlessly connected, and the driver will hardly notice it. When the vehicle's grip is reduced or the friction force in fast turning is low, the front motor will also be turned on in advance. Innovative technologies such as electric torque vector control function make the electric four-wheel drive system even more powerful, and inherit the excellent characteristics of traditional motion differential to electric vehicles.
When the curve accelerates, the power of the vehicle is comparable to that of a racing car, and the driving force at this time will be concentrated on the rear wheel. What if? ESC？ When the electronic stability control system is switched to the "sports" mode and the "dynamic" mode is selected in Audi's dynamic driving control system to achieve the best performance, the driving system will have better lateral dynamic performance and drift as needed. It can predict the driving behavior in real time and realize a high level of driving safety and reliability.
The installation position of high-capacity high-voltage battery is lower than three motors, which ensures the balanced distribution of body weight, and the low center of gravity of the vehicle provides great advantages for handling performance. Standard sports progressive steering system, the greater the driver turns the steering wheel, the more direct the steering ratio. In addition, the front and rear axles of the vehicle are designed with five links, and the suspension system is aimed at Audi e-tron? S series models have been specially adjusted to provide 7 driving modes. The adaptive air suspension system can change the height of the car body to 76 mm
Incredible achievements of drag coefficient: innovative aerodynamic design
Due to the optional virtual exterior rearview mirror (camera that sends images to the high-contrast display in the car), Audi e-tron? The drag coefficient of S model has been greatly improved. The wheel arch expansion is based on the aerodynamic concept, which innovatively reduces the drag coefficient of the car body. This innovative technology is a patented technology developed by Audi brand itself. At the same time, this is the first time that Audi brand has introduced this technology into large SUV models. Finally realized the Audi e-tron? S drag coefficient is only 0.28, Audi e-tron? s？ Sportback drag coefficient is only 0.26.
Another important component to effectively control the drag coefficient of vehicles is the controllable cold air inlet with cooling brake ventilation pipe. The air inlet should be kept closed as far as possible, so that the airflow above the range hood will hardly generate turbulence. Each e-tron model also comes standard with a heat pump to extract heat energy from the waste heat of the driving parts, thus extending the vehicle cruising range by 65,438+00%.
Audi e-tron? The S model adopts a three-stage energy recovery system, which also effectively improves the efficiency of the vehicle. When braking, the motor slows down alone, and the braking force can reach up to 0.3g, which can be felt in most daily driving. When the driving speed is higher than this level, the hydraulic wheel brake will work, but the motor will still keep running. When the vehicle is braked at a speed of 100 km/h, the motor can convert up to 270kW.
Full digitization of leading industry standards: control equipment, infotainment systems and auxiliary systems.
Like all Audi full-size models, Audi e-tron S and Audi e-tron s？ Sportback is equipped with a digital MMI touch response control system with a central display screen. On the third display screen-Audi virtual cockpit, the driver can choose to set up a special e-tron screen and put the electric drive system in the central position.
Users can also install a head-up display. MMI enhanced navigation control and infotainment system is standard. Its control system is the third generation modular infotainment toolkit (MIB? 3), with high processing ability, can complete various tasks well. The matching Audi communication box connects the vehicle with the environment and the passengers' smart phones.
The online service of Audi connect Internet technology complements the navigation system, especially the extended e-tron route planner, which can calculate the fastest route, including the best charging station location, according to traffic data, driver's driving style and charging interval. In some cases, the system will provide an alternative route. The charging point map, including relevant additional information, is updated online every day. When planning the route, users can give priority to charging stations that support the payment function of e-tron charging service.
