After Christmas, in this snowy season, AM car mirror came to Jilin City, Jilin Province, located in the northeast of China, when the temperature has reached minus 16 degrees. And all this is just for one thing, and that is to test the real range level of new energy vehicles in the Northeast, and it is a plug-in hybrid model.
The car that accompanies us to challenge this time is a sincere work of BYD Ocean Network - Corvette 07, the price of this model is 2028-28.980,000 yuan. The model that accompanies us through the challenge is the Corvette 07 2023 DM-i 205KM flagship, with an official guide price of 25980,000 yuan. Such a price covers at least 60% of consumers in the market, so as a model developed for most consumers, it should have an excellent level and be able to drive in most road conditions.
Please continue to look down, because what follows is a real endurance experience close to the actual car scene, and the charging port and fuel filler port of our car are sealed before departure.
In the morning, we need to carry out a pure electric range challenge, the road conditions are congested urban areas, mountain roads uphill and downhill, snowy roads and other mixed road conditions, requiring the air conditioning to be turned on to 25 degrees, the wind speed is 2 gears, the vehicle's common electrical equipment is not allowed to be turned off, driving in EV pure electric mode, and the SOC is locked to 25%. There must be 3 people in the car, and when the vehicle's pure electric range reaches 25%, the actual mileage will be recorded.
Although it is a plug-in hybrid model, the BYD Corvette 07 has a NEDC pure electric range of 205 kilometers, and if you want to use it for pure electric transportation, you don't want to spend too much on fuel, which is completely feasible. When the vehicle is going uphill, the motor can output powerful torque and pull the vehicle uphill. And after entering the snowy road, the driving resistance increases, and the corvette 07 is still very quiet and full of power.
The picture above shows the energy curve of our vehicle shortly after departure, and you can see the temperature of the air conditioner at this time, and the outdoor temperature at the time of the test was -12 degrees. In pure electric driving, there will be no average fuel consumption, and the vehicle is completely driven by the drive motor. In addition, the electrical equipment in the car is also to simulate the actual driving situation, after all, it is impossible to say that the heater is not turned on in such a cold place. But the pure electric driving engine did not start, and the heat energy ** cameThis is the heat pump air conditioner of this car, which achieves heating or cooling effect through internal reverse circulation, which is more energy-efficient than PTC air conditioner on other pure electric models.
In the end, the pure electric range in the morning was 1233 kilometers, at this time there is still 25% of the power left, the word HEV appears on the dashboard below because it has reached SOC 25% at this time, and the engine automatically intervenes, but in the energy curve in the figure below, there is no fuel consumption. The battery at the time of departure is 99%, and according to the NEDC cruising range of 205 kilometers, the range achievement rate is 81% under the conditions of -12 outside the car and 25 degrees of air conditioning in the car, but there are other members of this challenge who drive the same model, and the range achievement rate is as high as 9213%。
The challenge in the afternoon is to complete it in HEV petrol-electric hybrid mode, or our car, because the power has been run to 25% in the morning, and the SOC is locked at 25%, at this time the engine must intervene in the work, so it is 100% real fuel consumption measurement.
In the afternoon, the road conditions are urban congestion, intercity rural roads, highways and other complex road conditions, and the air conditioning is adjusted to 27 degrees. Corvette 07 can realize the series-parallel combination of motor and engine, when the power is lower than the set SOC value, the engine will drive the generator to work, replenish the battery, and drive the motor to drive the vehicle forward. With the replenishment and kinetic energy**, when the vehicle's charge is higher than the set SOC value, the drive motor will be responsible for driving during the start and low speed phases, and the engine will not work at this time. When more power is required, the vehicle can be driven directly by the engine. According to different working conditions, the corvette 07 can intelligently switch the working mode according to the driver's control of the accelerator pedal.
The most fuel-efficient working condition should be the engine working smoothly, providing power to the battery, and with the low and medium speed and starting, the power consumption depends on pure electric driving. And this is exactly the same as the performance of all of us during our daily commute, and we ended up driving a total of 1004 km, ran out of 100 km 45 litres of fuel consumption. (100 km on the meter 4.)The calculation standard of 6 liters is the total of electricity consumption + fuel consumption) Through the following**, you can clearly see the inverse relationship between fuel consumption and power consumption in the energy curve.
At the end of the day's challenge, let's briefly talk about the appearance, configuration and space, this time the color of our test drive is azure, which is actually blue but has a little silver, with the huge horizontal grille of the corvette 07, it looks both sporty and stylish. The length, width and height are 4820, 1920 and 1750mm, respectively, and the wheelbase has reached 2820mm, positioning it as a mid-size SUV. This size can actually fit into three rows of seats, but the Corvette 07 is a "big five-seater", leaving more luxurious space for passengers.
In addition to the luxurious space, there are also a lot of luxury configurations, in addition to L2 level intelligent driving assistance, it also comes with fatigue driving monitoring, multi-layer soundproof glass, HUD head-up display, front seat heating and ventilation, Dynaudio audio, car air purifier and other luxury equipment.
AM Car Mirror Summary:
Through this test drive, we proved that in the cold winter of the Northeast, the BYD Corvette 07 has a cruising range achievement rate of at least 80% in the pure electric state;The fuel consumption can reach 4 per 100 kilometers5 liters, not as some people who have not driven this car guessed, fuel consumption will rise quickly after running out of power. Combined with configuration and space, the corvette 07 is a "boutique car" in the same class, and from the point of view of the price, this car also has a particularly good cost-effective performance. Friends in the Northeast can rest assured that they can start, and the "small potatoes" in the South don't have to worry about anything.
