When it comes to new energy cars, BYD must be an unavoidable brand.
In the February 2022 new energy car sales ranking released by the Association, BYD successfully occupied three of the top five: BYD Qin, BYD Han, and BYD Dolphin.
If these three cars are put together, the most eye-catching thing must be bydirhan's medium and large sedan – the body is low, the lines are smooth, and most importantly, it is wide and large enough.
Like a cheese beef burger, the car is something like this, as long as it's big, the momentum comes out.

According to BYD's official data, BYD Han's sales volume in February 2022 was 9,290 units, and it reached 13,701 units in December last year. As of March this year, BYD Han's cumulative sales have exceeded 180,000 vehicles.
However, if you take the sales of Han DM and Han EV separately, you will find that BYD's main model is the pure electric drive Han EV, and the sales of the hybrid Model Han DM are stable at 2,500-3,000 units per month.

From the perspective of products alone, there are some regrets in this model of Han DM, and these regrets mainly come from the set of DM plug-in and mixing technology.
The 2020 Han DM features a third-generation DM system with a 2.0T engine and a matching 6-speed DCT transmission.
In order to solve the problem of excessive power consumption of the previous generation DM system, BYD added a BSG motor specifically for power generation to dm 3.0, and the frustration caused by the gearbox was effectively alleviated.

In terms of electric drive, BYD also added a 180kW rear motor to han DM, and under the joint action of the 2.0T engine and the motor, the han DM with a comprehensive power of 430 horsepower has a 4.7-second zero hundred acceleration performance.
But this generation of DM systems inherits the inherent disadvantages of inefficient internal combustion engines at low speeds.
According to the data of the car emperor, the measured fuel consumption of the 2020 Han DM is 7.88L per 100 kilometers, which is a good performance for a medium and large car, but the user's expectations for a plug-in hybrid car will obviously be higher. On the other hand, the 81km NEDC pure battery life provided by the 15.2kWh ternary lithium battery is also slightly embarrassing.
Compared to the zero-hundred acceleration of 4.7 seconds, the lower cost of use is obviously more attractive to home users.

BYD also seems to have noticed this problem, and two years after its release, BYD Han DM ushered in its "new version of the ship" - Han DM-i.
Cut fuel consumption and increase battery life
The EHS electromix system consists of a motor, dual electronic control, single gear reducer, motor oil cooling system, and direct drive clutch.
Han DM-i is equipped with a Special Turbocharged 1.5Ti Engine for Snap Cloud-Plug-in Hybrid, with a high compression ratio of 12.5, Miller cycle, ultra-low friction and other technologies, and its VGT variable-section turbocharger can be pressurized in a wider range of speeds, ensuring the boost effect under low-speed conditions.
This is just an appetizer, and the "soul" of the Han DM-i is not in this 1.5Ti engine, but in its EHS electromix system.
Unlike DM, DM-i does not have a traditional gearbox, BYD integrates the engine and drive motor, through the clutch to achieve the engine power generation and drive function switching, to avoid the engine in inefficient working conditions.
In addition to the HEV series/parallel mode in which the engine and the drive motor work together, under low-speed conditions, the engine does not directly drive the vehicle, but acts as a generator to provide power for the driving motor; at high speed, the engine directly drives the vehicle, effectively avoiding the loss caused by energy conversion.
After the replacement of the DM-i super hybrid based on electric drives, the fuel consumption of 100 kilometers of BYD Han DM-i NEDC has reached 4.2L, and the power loss fuel consumption of WLTC conditions is only 5.1L/100km.
The Han DM-i series adopts super hybrid special power blade batteries, divided into 18.3kWh and 37.5kWh versions, and the NDEC pure electric cruising range is 121km and 242km respectively, which is enough to meet the needs of two to three days of urban commuting.
In addition, due to the addition of large-capacity blade batteries, Han DM-i also has a DC fast charging port, which supports up to 80kW of boost fast charging, and the peak charging power of the Han DM-i 121km endurance version with a smaller battery capacity has also reached 40kW.
The reduction of fuel consumption and the improvement of pure electric endurance are the biggest progress of Han DM-i.
Performance energy consumption is grasped with both hands
Of course, in order to obtain low fuel consumption and long endurance, Han DM-i also has certain trade-offs in performance.
The driving form of Han DM-i has changed from the four-wheel drive of Han DM to the front drive, and the motor power of the two endurance versions is 145kW and 160kW respectively, and the acceleration time of 100 kilometers is 7.9 seconds.
While there are some compromises in terms of performance, there's no denying that 7.9 seconds is also a good result for a two-ton medium-sized sedan.
That being said, not everyone is willing to make a trade-off between performance and energy consumption, and someone will always shout, "I want it all."
If you want to give it to you.
At the same time as launching the Han DM-i, BYD also brought a Han DM-P with zero hundred acceleration of 3.7 seconds.
▲Han DM-p has the "3.7s" logo on the back
Han DM-p has a set of total power of 482 horsepower dual motor four-wheel drive system, in addition to the 160kW front motor, BYD also added a 200kW rear motor for it, under the blessing of the dual motor, Han DM-p acceleration capacity has exceeded many pure electric four-wheel drive models.
BYD not only gives Han DM-p amazing acceleration capabilities, but also successfully controls its NEDC power loss fuel consumption at 5.2L/km, while having a 202km NEDC pure battery life.
In addition, Han DM-p provides DiSus-C intelligent electronically controlled active suspension, which can intelligently adjust the softness and hardness of the shock absorber according to the road conditions and the driving state of the car, and improve the comfort and stability of the vehicle.
Of course, the improvement in driving texture needs to be verified by test driving.
The exterior interior is young, and the head-up display is a highlight
Finally, let's briefly talk about the changes in the appearance, interior and configuration of the new Han DM family.
For BYD's set of Dragon Face, everyone is already very familiar, the front face of the new Han DM has not changed much, but some small changes in the details have made the whole car more youthful and sporty.
For example, BYD changed the flat lines on both sides of the original front face to a more dynamic dragon fin shape, and the lines in the intake grille were also replaced by a dragon scale style, which is more fashionable. At the same time, the standard piano black kit of the whole series has also made the new Han DM much younger.
The biggest change in appearance is the taillights. The taillights of both models have been replaced by a new through-chinese knot design, which further improves the recognition.
The changes in the interior are also in the details, such as the optional "night purple" carbon fiber interior, Nappa leather and other interior materials.
What I am most satisfied with is the addition of four integrated sports seats, which echo the sporty style of the whole vehicle, and the wrapping of the seats is also very in place, if you don't like it, there are also dragon scale luxury seats to choose from.
In terms of intelligent configuration, the new Han DM is equipped with DiLink 4.0 intelligent network system, and the auxiliary driving system DiPilot has also been updated, adding functions such as high-speed road driving assistance system and emergency lane keeping assistance system, while supporting automatic parking in various scenarios.
In addition, the Han DM-i 242km battery life version and the Han DM-P are equipped with a W-HUD head-up display.
After the on-site experience, Dong Chehui found that the display area and display effect of BYD's W-HUD are worthy of recognition, but they are not particularly prominent in terms of information richness, and BYD still needs to be pondered in this area.
BYD's high-end dream
It is not difficult to see that the most important task of BYD Han DM-i is to suppress the fuel consumption and further reduce the cost of the user's car.
According to the data released by BYD on March 20, the cumulative orders of the new Han DM family in the pre-sale of 10 hours have exceeded 120.98 million units, and at present, DM-i is on the right path.
But launched the Han DM-p, a zero-hundred-speed car with 3.7 seconds? Does BYD need such a car? At first I didn't understand.
Until I saw byBYD announced the pre-sale price of 322,800 yuan, I understood.
The task of Han DM-p is to help BYD impact the high-end car market.
In 2020, BYD used the Han DM of 239,800 yuan to chase the 250,000 yuan joint venture model upwards, and two years later, BYD aimed at the long-occupied high-end car market of more than 300,000 yuan with the Han DM-p with battery life, performance and fuel economy.
The Han DM-p of 322,800 yuan is the beginning of BYD's impact on the high-end car market.
