Before sharing the BYD Song Pro DM-i car, it is necessary to have a small popular science on the Song car series, because when discussing this car in our fan base, many people do not know which BYD Song has.
At present, BYD Song car series is mainly divided into three categories, namely "Pro", "PLUS", and "MAX", Song MAX is easier for everyone to distinguish, because it is an MPV model, and "Pro" and "PLUS", it is indeed not very good to distinguish.
According to BYD, in fact, Song Pro DM-i and Song PLUS DM-i really do not have the same "grade" distinction as some friends imagine, and more differences between the two will be reflected in the design style of the vehicle.
Song Pro DM-i's vehicle lines are more straight and angular, according to universal aesthetic standards, Song Pro DM-i is more traditional, appears fiercer; as a "brother model", Song PLUS DM-i's shape, is with some "low lying" elements in (this is also BYD's statement), the whole car looks more sporty, more likely to be favored by young consumers.
In fact, compared with the difference in the appearance of the two cars, the core difference between song Pro DM-i and Song PLUS DM-i is the difference in sales network:
Song Pro DM-i belongs to BYD Dynasty Network sales, while Song PLUS DM-i is sold by the newly established Ocean Network.
In addition, according to the investigation of Cherujun, some owners of Song PLUS DM-i may mention the new car in the 4S store of BYD Dynasty Network, but please note that after the sale of the vehicle, it will be responsible for the BYD Ocean Network 4S store.
Two cars and two networks, for consumers at first may be a little confused, but for BYD, even if the Song PLUS DM-i is difficult to find, the timely launch of Song Pro DM-i is also very necessary, because this is all for the strategic layout after that.
After introducing the simple background information, let's talk in detail about the product quality of the Song Pro DM-i car.
How to say it, the first feeling of just getting started with this car, everything is basically the familiar taste of the recent DM-i model.
After getting the test drive, it was found that the vehicle's fuel gauge had nearly bottomed out, but there was still 63% of the electricity left. So before adding oil, even if the vehicle is adjusted to "HEV" mode, Song Pro DM-i almost always uses pure electric mode to drive.
This is also very much in line with the basic logic of DM-i super hybrid technology.
Because if it is a pure fuel vehicle, the most fuel-consuming period is nothing more than cold start, idle speed, low-speed creeping, and engine speed is too high working conditions; and as a hybrid vehicle, its biggest advantage is that it can call the vehicle's motor to drive the vehicle to the greatest extent under the low-speed working conditions of the vehicle, using the "zero start" characteristics of the motor and the energy-saving characteristics under low-turn conditions to achieve both fuel-saving and power-saving effects. Of course, the power consumption of the motor in the high rotation range is still relatively large, and the fuel is not enough to fill the motor.
When refueling, I found that the Xiaoyun-Plug Hybrid 1.5L naturally aspirated engine on the Song Pro DM-i we test drove only needed to be filled with No. 92 ethanol gasoline. At present, although many hybrid models have internal combustion engines/range extenders with high thermal efficiency, they can generally only be filled with No. 95 gasoline. Only a few, such as the Honda and Toyota hybrids, and weY's efficient hybrids, can use 92 oil.
After refueling, about 20% of the vehicle's electricity is left, so this is almost a vehicle test based on the feed state.
Since many BYD models of DM-i technology have been test-driven, individuals still have relatively studied the energy management logic of DM-i.
Referring to the figure above, enter the energy management interface of Song Pro DM-i, in the SOC (State of Charge, colloquially speaking, the ratio of charging and maintaining the power with the internal combustion engine) setting, you can see that the vehicle has two modes of "intelligent power protection" and "forced power protection". Although at this time, the SOC setting is set at 70%, in fact, at a uniform speed of about 120km/h, the battery energy of this Song Pro DM-i will always hover around 20%.
Looking back at the energy consumption list of this quasi-new Song Pro DM-i, the results are still quite good.
Officially, the fuel consumption of 100 kilometers has dropped to 3.8L, and the measured fuel consumption of 5.0L achieved at an average speed of 18km/h in the above figure is believed to be acceptable to most friends. So on the whole, how to explain the reason why Song Pro DM-i "can't charge" on high speed?
In fact, from the original intention of DM-i super hybrid technology, we can also roughly glimpse some core reasons. DM-i super hybrid is based on electric hybrid technology, when driving DM-i cars in the city, 99% of the working conditions are used to drive the vehicle, at this time, Song Pro DM-i, almost a pure electric car.
Or based on official data, about 81% of the working conditions, this Xiaoyun-plug hybrid special 1.5L naturally aspirated engine is in a stalled state.
In other words, the engine is in the ignition condition at about 19% of the operating conditions, and during this test drive, this ignition condition will appear relatively more frequently, so we ran out of the actual fuel consumption of 5.0L.
The idea of "elimination method" may be easier to understand the ignition logic of this engine of Song Pro DM-i, for example, in our test drive process, because the power battery is in a feed state for a long time, so in order to drive more efficiently, the internal combustion engine as a generator should consume fuel to replenish the power battery; but coincidentally, the road conditions when we set off are "one horse Pingchuan", so the driving style is to drive against the speed limit of 120km/h, at this time, the motor's "zero start" The characteristics and low-speed advantages can not be fully utilized, but the internal combustion engine enters a more ideal efficiency range, so the DM-i system chooses to directly couple the engine and the wheels, using the engine direct drive mode.
In other words, if the road conditions are better under high-speed conditions, compared with the logic of the general oil car, the energy consumption logic of dm-i super hybrid is closer to the tram, that is, the lower the speed, the more fuel-efficient.
So, what about the NVH performance of the Song Pro DM-i at high speed?
As a more traditional SUV model, the Song Pro DM-i should have made more noise, but it didn't. At least under the working conditions of 120km/h, the wind noise in the Song Pro DM-i car is still a level that can be accepted by individuals.
Why this conclusion was reached, we combined the following figure to expand the explanation.
Because the shooting time is relatively cramped, so first released such an interior drawing, is there no small detail about the wind noise of the vehicle?
Actually, the answer is on the inside of the rearview mirror.
Whether it is a car with a lower bow and streamline, or an SUV with a wider front and a larger crash area, if the wind noise between the vehicle's A-pillar and the rearview mirror is not properly controlled, it will produce additional wind cutting sound after a certain speed.
In the rearview mirror of the Song Pro DM-i, you can see a design similar to the three guide fins, so although the wind noise of the vehicle will obviously rise linearly with the speed of the hour, at least, it is "only" a linear rise, and at a higher speed, it will not produce almost any "abnormal" wind cutting sound, which can also reflect the intentions of BYD engineers.
By the way, this rearview mirror is also only the NFC car key function, compared to some brands of so-called "mobile phone electronic key", this contact skeuomorphic unlocking method, to be honest, will be more accepted by digital technology enthusiasts like me.
Back to the NVH part of the Song Pro DM-i, I was also pleasantly surprised by the Giti Control SUV 880 series tires on the vehicle, which had excellent road noise performance and hardly picked the road. After investigation, this set of tires is indeed in Giti's high-end sequence products, and friends who are interested in this set of tires may also refer to it.
After that, let's talk about the driving experience level of Song Pro DM-i, I believe this is not the focus of many potential passengers, after all, the positioning of the vehicle is a compact SUV for pure household use, and the pursuit is a kind of "reactive and blameless".
But I think that in addition to the basis of the above four words, Song Pro DM-i may also have some parts of the "super-gang", especially with its NVH performance, the isolation and filtering of its chassis can be in the head position of this price point. The suspension structure of the front McPherson and the rear multi-link linkage is consistent in the overall filter performance, neither soft to dangling, nor too hard to bumpy, not exaggerated, really some sense of luxury. Whether it is exaggerated here, or you need to experience it in the field.
In terms of riding space, referring to the figure above, the rear leg space of Song Pro DM-i is roughly such a performance, and the views of individuals and editors in the same car are basically the same, and the leg space of the vehicle seems to be slightly shorter than that of Song PLUS DM-i, that is, the difference in feeling, and it will not be obvious.
But another point of the above picture may have been found, although the rear legroom of the Song Pro DM-i is not as exaggerated as some competitors, but the adjustment angle of the back seat back can be more reclined, which is definitely a big positive for long-distance passengers.
In addition, the wrench for adjusting the back angle of the Rear Seat Chair of song Pro DM-i is actually arranged in a place consistent with the general front manual seat, which is very convenient. This is the first time that The Rut Jun has seen the simplest and most direct manual adjustment method in addition to the electric adjustment of the back angle of the seat. What pull rope, the back of the chair with a hand, one is difficult to find, the other is that perhaps the adjustment angle is not so large, talking is better than nothing, and Song Pro DM-i is really easy to use.
Write at the end
Combined with the guidance price of Song Pro DM-i 134,800 yuan - 159,800 yuan, it is believed that it will still become a hot product of the BYD DM-i family. Of course, the well-known question is not whether the car is worth buying or not, but how long it will take to mention the car.
