If you look NEDC mileage 470 km, later this month the upcoming Audi e-tron compared with the Tesla Model X, do not seem superior to others. After all, Tesla’s data is 575 kilometers. But once opened the e-tron, the vast majority of motorists experience is consistent, Audi is Audi, which is enough to power all the new energy automobile enterprises a good lesson.
two days measuring 800 km long, for you the next three drivers a detailed report on this sale price of pure electric SUV 70 million cases of exactly what features worthy of discussion.
pure tram life is metaphysics, security is the core issue
pure electric vehicle mileage It has become a metaphysics, although we are using NEDC standard uniform to mark parameters, but use a huge difference. For pure tram, users are most concerned about in addition to the mileage, the most important thing is safety.
aspects of Look mileage. Price is 700,000 Tesla Model X started its superior battery management technology 575 km endurance out data in the triple 100kWh of lithium battery capacity. Audi e-tron 470 km endurance is given at 95kWh battery capacity, weighing 2.6 tons from a driver of the vehicle body.
the Audi e-tron rectangular aluminum housing battery pack nominal voltage of 397 volts, the 36 battery modules, enhanced security and maintenance economy while Audi e-tron 8-year / 160,000 km warranty.
aspects of Look battery safety. Tesla extension of the cylindrical battery Panasonic provided, but replaced by more 21700 from 18650 SpecificationSpecifications, reducing the number of unit cells, which is said thermal management system has been improved, after trying to avoid thermal Model S consecutive failure accident.
e-tron Audi uses the thermal management system having four loops, to cool the motor, power electronics and chargers, while high-voltage battery for car air-conditioning and heating or cooling. By using the waste heat of the vehicle wherein the heat pump air conditioning system for the vehicle, so that the e-tron Audi Mileage 10 percentage increase.
The thermal management system to maintain the battery also ensures optimum efficiency range of 25-35 deg.] C, such as during charging DC It can dissipate the heat generated by the resistance, and the battery is heated in the winter, and in turn improve the charging efficiency extend battery life.
Look charging convenience. Audi e-tron support up to 150 kilowatts DC charging, although the percentage of 0-30 and the same will trickle protection measures after the 95 percentage, but still fast charging speed. The only regret is that the current DC charging pile Guodian provide maximum support 120 kilowatts, but also by the equipment and other restrictions in use, this test drive to experience only once charged up to 100 kW of power, most of the charging post can only provide 50 60 kilowatts.
Also to be emphasized that the energy recovery Audi e-tron endurance percentage contribution of 30. Energy of the motor can achieve three levels of recovery energy recovery (0.1g, 0.2g, 0.3g), during driving can also be replaced by a reduction brake lever shift paddles and achieve energy recovery.
e-tron Audi for the average home user, the vehicle support 11 kilowatts AC charging, manufacturers will be presented 7 kW AC charging wall boxes and free on-site installation services.
as the most pure tram fuel vehicles, driving the texture of how to achieve
Audi e-tro from public MLBEvo platform, the more Tim Bentley, Lamborghini URUS, A new generation of Cayenne and Audi Q8 are from this platform, and therefore the Audi e-tron gene with premium performance of the car. The two-day test, the car gives the greatest feeling is that, unlike most electric cars electric cars, then embodied in those areas?
In the body size, the car length of 4901 mm, a full length of 30 mm below the Cayenne, 1935 mm wide, 1628 mm high, 2,928 mm wheelbase, front and rear have enough space experience. In terms of storage space, the rear luggage compartment 600L, the front hatch under the storage box 60 liters practical, if the rear seat back flat, luggage space up to 1725 liters.
In the power output, the Audi e-tron a longitudinal axis of each induction motor, the total output power of 313 kilowatts and 664 N • m of torque, hundred mph 5.7 seconds. Tesla also like to use asynchronous motors, permanent magnet synchronous motors and in fact have their own strengths, but a different technology directions.
while driving, this car gives the greatest feeling is to accelerate as traditional fuel vehicles, there is an open texture AT gearbox car. However, after all, it is an electric car, no sound when it starts. After starting no crawling, it must depress the accelerator pedal to travel. When the brakes, the car’s kinetic energy recovery will first intervene actively slow down.
In a core configuration, the whole system comes standard with air suspension, the driver can switch seven kinds of driving modes: automatic, comfort, dynamic, efficient, individualized, the whole road and off-road, but also air suspension It will automatically adapt to the appropriate driving mode. Pneumatic spring according to the driving speed and the driver’s preferences, can be individually adjusted for road conditions.
Conventional car clearance of 170 mm. On the highway, the vehicle body can be further decreased 26 millimeters, to enhance stability reduce air resistance, thereby extending driving range. In the “off-road” mode, clearance may be up to 35 mm. If the drive select the “Lift” function, the body can additionally be increased by 15 mm.
In the chassis suspension design, front and rear five-link design, after a variety of road driving and riding experience, giving people the feeling is directly biased towards comfort under most car models.
Southern winding road in the region for longitudinal Audi e-tron profound experience five-link suspension design, the suspension lateral movement of hard, soft and flexible vertical, both to improve the comfort, but also enhanced driving dynamics performance.
In the automatic steering assist, the standard progressive steering ratio of the steering system arranged directly adjusted steering angle. Upon transfer to bend, will not understeer; high-speed driving, to maintain a long and stable direction; at low speeds, power steering increase.
In the brake system design, Audi is the world’s first mass-produced electric vehicles in use in integrated electro-hydraulic system Manufacturer motion control system, the system module weighs less than 6 kg, lighter than conventional braking system 30 percentage. Emergency braking, the system provides maximum braking force within 150 milliseconds, compared to traditional fuel vehicle braking distance reduced by 20 percentage.
e-tron Audi first brake kinetic energy recovery system involved, if insufficient energy recovery torque, brake hydraulic displacement of the piston means will generate additional pressure, giving the experience is very resilient brake, and not be slow.
Meanwhile Audi e-tron cleaning with a brake, the brake disc can help avoid oxidation and prolong life .
in a four-wheel drive system performance, in general, e-tron primarily rear portion of the motor, driving force distribution of the rear axle is generally biased, if a higher power, the electric four-wheel drive system as needed redistribution of the torque to the front axle.
while the first central suspension control apparatus integrates the operation of the controller and a vehicle drive system QuattroSelect wheel torque control. If it is detected in the motion understeering driving, braking load will be slightly smaller inner wheel, so that the driving force of the outer guide wheels; driving on ice and snow, fast cornering impending slip, and vehicle presence or understeer oversteer, the system will assign the drive torque based on the prediction.
As a result of an electric four-wheel drive system, no mechanical clutch involved simply transmit power, compared to conventional Quattro, the system detects the torque speed driving conditions and motor output faster, only about 30 milliseconds.
[Test drive summary] experienced a highway, urban road congestion, winding road winding ups and downs, total mileage of more than 800 kilometers, the Audi e-tron to the driver brought the biggest surprise than their travel texture. In addition to undifferentiated driving experience and fuel outside the car, we tested the overall mileage of 400 kilometers, which for a 470 km NEDC Mileage pure electric SUV, the conversion efficiency of more than 85 percentage. As for the whole car comes standard with a variety of configuration and use of technology is very convenient three displays, fully embodies the luxury brand’s style. The only let for the first time to open the car’s driver than the cortex of the file slightly ignorant of the circle can not move, shift your fingers need to push the side button.
