In the domestic compact car market, the joint venture brand has occupied an absolute dominance for a long time, and many of the mainstream models have taken the "benchmark" as their own, while the independent brand cars can only strive for sales at low prices and high matches. However, in recent years, with the popularity of new energy vehicles, independent brands have begun to advance by leaps and bounds, and winning by technology is no longer a fantasy, and at present, BYD's DM series is more top-notch, and Qin PLUS DM-i is one of the representative products in the brand.
On the other hand, Geely also launched the Thor Hi · X "Super Electromix", while Emgrand L Thor Hi · X is equipped with Thor Hi · X's first car, Emgrand has always occupied a very large share in the home market, this time Emgrand L Thor Hi · The arrival of X not only represents Geely's latest hybrid technology, but also competes with BYD Qin PLUS DM-i to seize the compact hybrid home car market. What kind of spark will occur when these two domestic hybrid cars "collide"? Let's compare.
01
Which fuel consumption endurance is stronger?
The technical highlights of each of the two vehicles
In terms of mileage, Emgrand L Hi · X's pure electric mileage is more than 100 kilometers, the comprehensive mileage under full oil and full power can reach 1300 kilometers, and the comprehensive fuel consumption of 100 kilometers even under the state of loss of electricity is only 3.8 liters, which is the same as the level of BYD Qin PLUS DM-i, and the comprehensive fuel consumption of these two models is significantly better than that of Toyota Corolla Dual Engine, Honda Lingpai and other competitors.
Looking at the official data alone, the acceleration time of 100 kilometers, the comprehensive mileage and other aspects, the Emgrand L hybrid will be slightly better, but the fuel consumption of both vehicles is 3.8L/100km. But these are only representative of the official best data, in fact, each driver's driving experience and road conditions are different, there will definitely be errors, so the above data is for reference only. So, what are the unique technical highlights of the hybrid system of these two models?
1. Geely Thor Hi · X Hybrid
First of all, Raytheon Power is only a broad general term, and its technology is to include a 1.5TD/2.0TD hybrid special engine, as well as a DHT (1-speed transmission)/DHT Pro (3-speed transmission) hybrid special transmission, which supports full coverage of A0-C class models, and covers a variety of hybrid technologies such as hybrid, plug-in hybrid and extended range.
The engine technology highlights are mainly high-pressure direct injection, supercharged intercooling, Miller cycle, low-pressure EGR four technologies, in the thermal efficiency part is more than the highest level of Japanese hybrid 41%.
Compared with the engine, Thor's hybrid special gearbox is a bigger point of view. Operating logic, dhT Pro can also achieve pure electric, series and parallel modes.
Working logic
1. Pure electric mode is that the P2 motor drives the vehicle alone, and it is completed when starting or accelerating with a small throttle;
2. In series mode, the engine charges the power battery pack through the P1 motor, and the P2 motor is responsible for driving the vehicle.
And adjust the engine load. With pure electric and series mode, the system efficiency is increased by 30% compared to traditional models;
3. In parallel mode, the engine will drive the vehicle directly, and the motor will assist the force. During braking, the motor also achieves 100% kinetic energy recovery.
It should be noted that Geely's hybrid system also supports full-speed parallel connection, and the system with a speed of more than 20km/h can enter the parallel mode, one to reduce energy loss by using the efficient working range of the engine, and the other to release 60% of the reserve power with the help of a three-speed transmission.
And Emgrand L Hi · X is equipped with a 1.5TD-3DHT Rcex Hybrid System, which has a maximum endurance of 1300km when full fuel, an acceleration time of 0-100km/h in only 6.9 seconds, and a fuel consumption of only 3.8L/100km.
2. BYD DM-i
BYD's DM hybrid system has developed to the third generation, it is mainly based on the dual clutch transmission to create a hybrid power, although it focuses on new energy, but in terms of performance performance is far more prominent than the "new energy" attribute. In order to meet the needs of different users, BYD divided it into two and launched DM-p and DM-i dual platforms, focusing on performance and economy respectively.
The most significant feature of the DM-i system is that compared with the conventional hybrid technology, the "oil hybrid" of the hybrid system is created from the perspective of the oil truck, and BYD is standing in the perspective of the tram to do the hybrid, using the "electricity-based" technical route, which is also directly related to BYD's long-term investment in the three electrics, meeting the performance indicators at the same time, the cost is also controlled.
The principle of BYD DM-i hybrid system is to use high-power motor drive + large-capacity blade battery energy supply on the architecture, and the engine is in the efficient speed range under most working conditions to generate generators, realizing the fuel-saving purpose of using less oil and more electricity. Its components include the 7-in-1 highly integrated EHS Super Hybrid System, the 1.5L/1.5Ti Snap Cloud-Plug-in Hybrid High Efficiency Engine, the DM-i Super Hybrid Special Power Blade Battery, and the Vehicle Control System, Engine Control System, Motor Control System, and Battery Management System.
The EHS electromixing system is also the core of DM-i super hybrid, which adopts a dual motor structure with series-parallel architecture, which can realize pure electricity, series, parallel, energy recovery and other working modes.
Working mode
1. When the power is sufficient, it can be equated with a pure electric vehicle model, and the battery directly supplies the motor to drive the vehicle;
2. When the power is insufficient, the engine will drive the generator to generate electricity, ensuring that the motor drives the vehicle while charging the battery;
3. When it is necessary to accelerate overtaking, the engine and drive motor will drive the vehicle at the same time, which can provide abundant power;
4. When cruising at high speed, the engine is in the efficient speed range, and the engine will directly drive the vehicle.
It can be seen from this that 81% of the vehicle is driven by electricity; 18% of the working conditions of the engine is driven in series in the efficient zone; so that 99% of the working conditions are driven by electric motors, which is also the core of the DM-i system.
The EHS mixing system is available in three power versions: EHS132, EHS145 and EHS160, and the system of different powers can be adapted to all models of the A-C class. The engine corresponding to the electric hybrid system with different motor power is also different, the EHS132 and EHS145 use the Snap Cloud-Plug Hybrid 1.5L engine, and the EHS160 uses the Snap Cloud-Plug Hybrid 1.5Ti engine.
The Xiaoyun-Plug-In 1.5L engine has a variety of highlights such as Atkinson cycle, ultra-high compression ratio of 15.5, high EGR rate of low-temperature exhaust gas recirculation, split cooling technology and wheelless train design, making the thermal efficiency of the Xiaoyun-Plug-Blend 1.5L engine as high as 43.04%. The Xiaoyun-plug-and-mix 1.5Ti engine has a compression ratio of 12.5, and the thermal efficiency of the 1.5Ti engine has reached 40% under the bright spots of Miller cycle, variable-section turbocharger and ultra-low friction.
In terms of batteries, BYD DM-i models use 10-20 dedicated power blade batteries, which are known to have different battery pack capacities such as 8.3kWh, 9.9kWh, 18.3kWh, and 21.5kWh.
The Qin PLUS is equipped with BYD Xiaoyun 1.5L naturally aspirated engine, and in terms of motors, the 55-kilometer pure electric endurance version is equipped with the electric hybrid system EHS132, the maximum power is 180 horsepower, and the maximum torque is 316N·m. The 120 km endurance version is equipped with the electric hybrid system EHS145, with a maximum power of 197 horsepower and a maximum torque of 325 N·m. The two lithium iron phosphate batteries have capacities of 8.32kWh and 18.32kWh, respectively. , and in the full fuel state, the cruising range is as high as 1245km, and the fuel consumption is only 3.8L/100km.
In terms of engine technology, Geely and BYD have invariably adopted similar technical routes, and the main focus is to reduce the load brought by the engine accessories and achieve the improvement of engine thermal efficiency, both of which have reached more than 43% thermal efficiency.
In terms of gearbox, Geely's transmission technology uses a multi-gear planetary gearbox, and BYD is a simple single-speed direct drive transmission, just like the difference between Toyota hybrid system and Honda hybrid system. Each has its own advantages in terms of smoothness and efficiency, but it is undeniable that BYD's EHS single-speed direct drive transmission is more advantageous in terms of cost.
The same high thermal efficiency engine, each with its own advantages of the gearbox and control logic, it is not easy to distinguish between Thor power and DM-i, and it may be necessary to wait for the real car experience to be compared to have a final solution.

Who looks better?
Emgrand L Hybrid has a distinct personality, and Qin PLUS DM-i is young and stylish
Emgrand L Thor Hi · The overall appearance of X is consistent with the fuel version, using the "energy storm" design language, and the most important change in the front face is that the logo adopts Geely's new digital streamer logo, and the overall recognition is greatly improved.
Qin PLUS DM-i appearance family recognition is still very high, BYD's classic Dragon Face "dragon face" in Qin PLUS DM-i again evolved, the look and feel is more fashionable.
Emgrand L Thor Hi · The exterior design language of X "Energy Storm" is indeed very novel, coupled with the use of Geely's new digital streamer logo, which shows more personality; and BYD's classic Dragon Face "Dragon Face" has evolved again in Qin PLUS DM-i, further highlighting the charm of BYD's design. As for who looks better, it is a matter of seeing.
03
Whose interior cockpit is smarter?
Emgrand L Thor Hi · X adopts an exclusive interior color scheme, and the interior lines are more simple and atmospheric, and the sense of sport is no longer emphasized. The full LCD instrument and central control screen adopt the design of 10.25 inches + 12.3 inch HD LCD dual large screen, and the system adopts the same as the Star Vietnam L Thor Hi · X same Galaxy OS system.
Qin PLUS DM-i sub-interior layout is still a classic wrap-around design style, and provides two different colors for consumers to choose according to their preferences. The central touch screen is also equipped with the latest DiLink 3.0 car machine system of the family, which supports remote OTA upgrades.
Of course, whether you want to buy a transportation or a family car, the configuration will be the place where consumers consider. Below, we have selected two models with a price difference of 0.12 million for comparison.
As can be seen from the above table, the configuration of the Qin PLUS DM-i will be more abundant in the two models with similar prices, compared with the Emgrand L hybrid, more remote parking/driving out, screen rotation, rearview mirror lock automatic folding, external mirror heating, automatic headlights/headlights delayed closing, etc. The Emgrand L Hybrid has more multi-screen interaction, car air purifier, negative ion generator and so on than Qin PLUS DM-i.
04
Who has more room?
Of course, for consumers who buy cars, spatial performance is also one of the core points of their concern. From the perspective of body size, Qin PLUS DM-i will be more dominant, regardless of length, width and wheelbase will beat the Emgrand L hybrid.
In terms of actual riding space, due to the height, weight and other factors of the experiencer cannot be unified, the following effects are for reference only.

Power/ride performance comparison
In terms of power, Emgrand L Hi · The X model is equipped with a 1.5TD-3DHT Ray Smart Engine hybrid system, and the drivetrain is a 3-speed electric drive transmission (DHT Pro).
Qin PLUS DM-i is equipped with a Special 1.5L engine for Xiaoyun-Plug-in Hybrid, and in terms of motors, the 55-kilometer pure electric endurance version is equipped with the electric mixing system EHS132, the 120-kilometer endurance version is equipped with the electric mixing system EHS145, and the matching gearbox is the E-CVT stepless transmission.
Since we have not yet test-driven the Emgrand L Hybrid, the following is the performance of the Qin PLUS DM-i ride:
This time, we test drive the model for dm-i55km flagship version, but it and the 120km model in the acceleration performance is no gap, the first feeling of driving it is cheerful, are that very brisk feeling, the throttle with the opening will continue to give power output, and almost in a pure electric way in the drive, the engine is not directly involved, and when you need the engine to intervene, you only need to step on the accelerator pedal deeply, will wake up the engine power, then it will be the time when the HEV really starts.
Secondly, the biggest feeling brought to me is quiet, driving it really has a feeling of opening a pure electric model, because most of the time the engine will not intervene, so it is impossible to detect the speed of the working noise, in addition to the Qin PLUS DM-i has a good aerodynamic body design, greatly avoiding too much wind noise interference, and tire noise suppression also benefits from the choice of low rolling resistance tires, taking into account the quietness of daily driving but also has a certain role in reducing fuel consumption.
Another advantage is also necessary to say, that is, when the engine intervenes in the moment, if you do not carefully perceive it, it is really difficult to find its conversion process from pure electricity to oil-electric hybrid, because it is really too smooth, there will be no slight sense of abruptness, so it is almost a seamless process, and it does directly help to improve the quality of driving.
Energy recovery is divided into two adjustable, standard and stronger. In the standard mode, it is also impossible to detect the drag and tearing feeling brought about by its braking force recovery, and in the stronger mode, there is only a slight sense of braking force feedback, which will not affect the driving itself at all, and it is also very necessary for the driver and occupant to ensure comfort.
Suspension performance, the suspension combination of the front McPherson rear torque beam is also the standard of 150,000 yuan of this level of model, Qin PLUS DM –i tuning is still a little harder, especially through the speed bump and groove, the low-speed filter effect is OK, but when passing at high speed, the spring rebound will be somewhat untimely, there is a little hard feeling, for the rear passengers, this bounce is still more obvious, the later hope can be some optimization of the suspension damping, the effect will certainly be better.
Finally, its killer or fuel consumption performance, the official state of power deficit comprehensive fuel consumption is only 3.8L / 100 km, such a strong fuel consumption performance I believe must be its competitor model like a blow, for the owner is definitely happy, to know that the 120km version of the model in the case of full power and full fuel, is easy to last more than 1200km, no matter who it is, I think it can meet your long-distance needs.

Summary of the full text
Aside from the appearance and interior, after comparison, we can see that whether it is the 3.8L/100km power loss fuel consumption of the two, or its full power cruising range (Emgrand L hybrid is 1300km; Qin PLUS DM-i is 1245km) and 100 km acceleration (Emgrand L hybrid is 6.9 seconds; Qin PLUS DM-i is 7.3/7.9 seconds), Emgrand L hybrid is slightly better, absolutely capable of just Qin PLUS DM-i, And the new car launch (subsidized price: 12.98-145,800) has already earned enough attention during this time.
But in the compact hybrid sedan market, Qin PLUS DM-i (official price: 11.18-15.18 million) as a pioneer, has withstood the test of the market, and its sales volume says it all. So for now, the early stage of Emgrand L hybrid still needs to be tested by consumers first, if the product force is indeed hard enough, then the future and Qin PLUS DM-i are equal to autumn. As for the two models, how to choose? I think you should have the answer in your heart.
