Dog Brother Original BYD Super Hybrid DM-i Deep Experience (Power Principle High Speed Performance)

Hello everyone, I am a dog brother, a local car critic in Yantai who focuses on the in-depth experience of domestic cars. I advocate that a car should not be sloppy, and I tend to drive a car home for a few days, so as to truly experience the details that many car owners can experience.

Dog brother evaluates the car and test drives for you.

Today I want to talk about a very popular model, that is, BYD super hybrid DM-i model, the specific test drive model is BYD Song pro DM-i.

This is a mainstream dmi model with a high-power single-drive motor and a 1.5-liter naturally aspirated hybrid engine. I don't want to list the specific parameters, you can check it yourself, I only say what I actually experienced.

Before driving up, I had some questions about DMI, which were answered after the test drive.

Whether the urban power is enough

The first is that I think the power of this car may be relatively weak, mainly because this car plus the battery is not light, and whether the 1.5 self-priming engine can pull is a question mark.

Actually open up, the power is no problem.

First of all, in the working logic, dmi is based on the motor, the start and low speed are electricity, equivalent to a pure tram, in the ordinary mode, the speed of 70% or less 100% electricity, due to the motor power is relatively large, at this time the dmi model is equivalent to a high-power pure tram, the start is fast and agile, fast speed. If it is a sport mode, the start is still pure electricity, the starting floor oil will ring the tire, the low-speed electricity but the engine will start to drive the vehicle at a speed of about forty.

Taken together, the dmi model urban power experience is quite good.

But it needs to be reminded that the dmi model in the city most of the time is a pure electric car, the speed of the fast is also the kind of electric car, not abrupt, the impact is not strong, sensitive and fast, and the power of the oil car is completely different, and the intervention of the engine above 70 also increases the staying power of the car.

At the same time, because there is a high-power motor, the lack of power that we are worried about in the 1.5 self-priming engine does not exist.

However, the style of the dmi model is more comfortable and soft, so it is not the wild drag racing steel cannon type, and it is more suitable for family transportation.

What is the high-speed acceleration capability?

Another big question mark is the problem of high-speed acceleration capabilities. Because in the urban area, the motor is the mainstay, and on the high speed, it mainly relies on the gasoline engine to drive directly, at this time, whether the 1.5 self-priming engine can pull the car is also questionable.

So I drove this BYD Song Pro Dmi on the highway, when the temperature was about 11 degrees, and the pure electric battery life remained 24%.

The power performance greatly exceeded my expectations, I tried 60 to 100, 60 to 130, 100 to 130, each speed range this car showed a good acceleration ability, high-speed overtaking clean and sharp, the most worrying speed of more than 100 power performance and the general 1.5t oil car high-speed power performance is almost enough.

Chassis performance

Judging from the BYD Song Pro dmi I test drove, the chassis of this car does not have too many technical highlights in the structure, and even some people complain that the structure is simple. But the actual opening effect is good.

This car due to the characteristics of the hybrid car, the weight of the car is heavier, so when driving in the urban area, it is obvious that it can be pressed, relatively stable, the tuning of the entire chassis does not emphasize the sport control, and more is more comfortable and stable, and the pit speed reduction belt will not be too loud and jumpy, the overall chassis performance is more close to the Japanese chassis style, specifically, this car is very similar to about 200,000 Japanese cars, and the chassis is enough for family transportation.

In addition, on the high-speed ramp to maintain more than fifty speeds over the corner, the body did not have obvious roll and discomfort. High-speed normal overtaking is also relatively stable, there is no feeling of drifting, and the speed of 130 overtaking is also more confident.

BYD DMI's working logic

BYD DMI is a great creation.

Oil cars and electric vehicles have their own pain points and cannot be solved.

Oil truck refueling is convenient, high efficiency, but the noise jitter control can not be compared with electric vehicles, in addition to the oil price running ten dollars to go, originally many people because of the high price of oil to drive buckle search, now simply can not afford to drive.

Electric vehicle electricity, a kilometer of electricity cost a dime, no jitter no noise, fast speed, less maintenance of problems, no need to change the oil. But the winter endurance discount is not solved, open the warm air endurance and then discount, high-speed endurance discount, if you catch up with the winter long-distance high-speed that will be fatal, discounted, and high-speed charging delay time, so hundreds of thousands of electric vehicles, running high-speed are very troublesome, there is no way to play the main model at home.

BYD DMI uses oil-electric hybrid, mainly electric motors, if opened in the city, it is basically a pure tram, pure tram all kinds of benefits are readily available, most of the time the engine is used to generate electricity at a fixed speed. Therefore, the DMI model can be completely charged, completely avoiding the endurance anxiety of the electric vehicle.

In addition, DMI and pure range hybrid and different range extender hybrid vehicles can only use electricity at high speed, while the motor is inefficient at high speed, DMI models can use engine direct drive at high speed, using the characteristics of gasoline engine high speed and fuel saving efficiency.

Therefore, BYD plugs in the mixed DMI is equivalent to two cars, the urban pure electricity and fuel saving are quiet and comfortable, the speed is sensitive and the cost is low, and the direct drive force of the high-speed engine is enough without endurance anxiety. And if there is no charging condition at home, you can also use oil and not charge at all.

A different oil car, BYD DMI's little secret

As mentioned earlier, if there is no charging condition at home, you can drive the DMI model as a fuel vehicle, then everyone will definitely have doubts, is this not the same as the fuel vehicle? It's not the same at all.

First of all, the core of DMI is electricity, so even if it is a state of loss of electricity, the start and low speed of the urban area is also electrical, and the engine is constant at a speed of about 1300 in power generation, converted into fuel consumption, about 100 kilometers of two or three oil looks, and in the state of electricity, the fuel consumption of the traffic jam is much more than that of the fuel vehicle, which is the root cause of the low fuel consumption of the DMI power loss state, the urban power loss fuel consumption is more than five, and the same road conditions The fuel consumption of the fuel vehicle may be more than twice that of this.

In addition, this is not all, the power performance of the plug-in hybrid model is also completely different from that of electric vehicles and oil vehicles.

In terms of power, the oil car has a gearbox and the gasoline engine has a low speed torque, and the start is slow, but the staying power is enough. Pure tram started quickly but lack of stamina, especially high-speed crotch, and dmi will combine the two, starting by relying on high-power motors to be hard, low speed or play the low-speed advantage of the motor, the speed of the car after 70 to the gasoline engine power performance advantage range, the engine directly driven.

Therefore, the low-speed agility of the plug-in dmi model has the same staying power as the oil car.

Now you should understand why I say that dmi is a great initiative, right?
