For professional reasons, we will be invited to participate in the actual fuel consumption measurement every time a new car is launched. Everyone knows the moisture in
better than me. Most of the tests are in second and third tier cities. Manufacturers will find a specific section with fewer cars and fewer traffic lights for the media to measure. We are all clear in our hearts that the measured fuel consumption is nothing more than a formality, but everyone can see through it.
What I did not expect is that this time BYD Qin PLUS DM-i will be tested in Shenzhen. Friends who know me know that I often complain about the traffic in Shenzhen, especially during the morning rush hour, which affects my mood for the day. This is the fastest-paced city in the country. The morning rush hour has come before the day is bright. On the way to , Futian and , the taillights can stain the sky scarlet.
Congestion is definitely a big taboo in fuel consumption testing. We all murmur in our hearts, for fear of measuring excessive fuel consumption. On the contrary, the manufacturer was open-minded and told us before departure, "It's just as good as driving your own car if you want to test it boldly."
Vehicle information
Before the start of the fuel consumption test, talk about the driving conditions. The Qin PLUS DM-i is equipped with the DM-i super hybrid system. The biggest difference between it and the BYD plug-in hybrid models we have contacted before is that the DM-i pursues the ultimate fuel saving, while the previous plug-in hybrid is the DM-p More pursuit is super power.
But that being said, its official 100km acceleration can also reach 7 seconds.
Qin PLUS DM-i is divided into pure electric battery life 55km or 120km two versions, this test is pure electric battery life of 55km version. I originally thought that the manufacturer would fully charge the battery before letting us test it. After all, this is the usual routine of plug-in hybrid models, using electricity first and then oil. But this time is different. BYD asked us to measure the fuel consumption of Qin PLUS DM-i in a power-loss state.
Before departure, the battery power is maintained at 25% of the state of power deficit, the fuel is added to the liquid level, and the mileage record of the car meter is cleared. In addition, as the first batch of cars tested, the total mileage of this Qin PLUS DM-i is less than 2,000 kilometers, which definitely represents the status of a new car.
Everything is ready to continue, the arrow is on the string
Since the manufacturer is so open-minded, in every aspect, I try to simulate the daily use of the car as much as possible, so after getting on the car, I did not care too much about the fuel-saving method. , And adjust the kinetic energy recovery to the maximum, which is also the most commonly used mode match for users.
The fast road conditions of the first 32 kilometers are fairly smooth and the average speed is higher. At this time, you can feel the engine intervening to work, assisting the drive, and actively recharging the battery, and the battery has been charged up to 28%. After 22 kilometers, it enters a congested section of the city. At this time, 99% of the stop-and-go traffic is driven by electric motors.
There is a very interesting phenomenon here, because most of the low speed is electric drive, so the more congested, the more fuel-efficient situation appears, the indicator shows that the fuel consumption is actually lower than that in the elevated and smooth passage conditions. This phenomenon mostly appears on Toyota's dual engine . Qin PLUS DM-i can achieve this performance, refreshing my new understanding of plug-in hybrid models.
actual test results
announced the results, all the test model results are lower than the official 3.8L/100km fuel consumption data announced earlier, we take the average fuel consumption of the test model 100 kilometers to talk, because this is often the most representative.
After driving 109km, Qin PLUS DM-i's comprehensive fuel consumption per 100km is only 3.18L/100km. And this is still the result measured under the power-deficient state, if it is fully charged, the result will be even lower.
In addition, this time the manufacturer also rented several Japanese pure-fuel vehicles with a reputation for fuel efficiency at the same price for comparison. With the same route and the same road conditions, the average fuel consumption of Japanese-brand fuel vehicles is about 5.4L/100km. The purpose of finding a competing car is not to compare the fuel consumption with Qin PLUS DM-i. After all, one pure oil and one hybrid are not comparable.
This, in my opinion, better proves the authenticity of the test. The 5.4L/100km fuel consumption of Japanese pure fuel vehicles is also the result of most users' daily use. Under the same route, Qin PLUS DM-i will give you even greater surprises.
analysis results
Qin PLUS DM-i can get such good fuel consumption results, in fact, in addition to the very efficient power system, I think there are several points.
first is the kinetic energy recovery mode, which in this fuel consumption test its kinetic energy recovery efficiency impressed me. In urban congested road conditions, releasing the throttle can even help you recover until you stop. I have tested many hybrid vehicles of joint venture brands, and most of them will have no recovery after reducing you to 10km/h.
In addition, the average temperature of the test that day was about 8℃, which is one of the few "severe cold" seasons in the south. Netizens who have known electric vehicles must know that low temperature is fatal to battery life, but Qin PLUS DM-i hardly feels much influence.
Later, I asked the engineer this question, and learned that Qin PLUS DM-i is equipped with BYD DM-i super hybrid special power blade battery. The excellent thermal management system of the blade battery was when we tested the Han EV in Beijing. Have seen it.
At the same time, there are also previous official measured data showing that the discharge capacity of the blade battery is maintained at 90% at minus 20 degrees Celsius. In the case of low temperature and low SOC, it performs better than the ternary lithium battery and is less affected by temperature.
The second is the tires. Qin PLUS DM-i uses Continental's EcoContact 6 tires. From the tire name prefix "Eco" you can know that this is a tire with low rolling resistance and low fuel consumption. This also helped Qin PLUS DM-i achieve the ultimate fuel-saving results.
written at the end
from the actual fuel consumption measurement of Qin PLUS DM-i, in fact, it can be concluded that the electrification of automobiles is not to kill the fuel vehicles, but to reduce the burden on the engine on the new electrified platform. To become a super-efficient power system, this is the model users want.
Obviously, BYD at this stepIt is ahead of all manufacturers and has made a good demonstration. Its performance is comparable to that of a turbo car. It can be driven as a pure electric car. In the case of power loss, its fuel consumption can be lower than Toyota Shuangqing and Honda i-MMD. Can also get a green card.
The rest will be handed over to the market, and the sales of Qin PLUS DM-i will tell everyone that this is the development direction of new energy vehicles.
