Geely's Thor Hybrid, more advanced than DM-i? Can BYD be pulled off the altar?

Hello, everyone!

Geely Star Yue L Thor Hi · X hybrid version was officially launched a few days ago, the biggest highlight of the new car is to replace the new hybrid system, focusing on a lot of innovation and upgrading in technology, the strength can not be underestimated. The potential rival is DIRECTLY ATD's DM-i.

So can the Geely hybrid pose a threat to BYD? Which of these two self-developed hybrid systems is more powerful? Today we will talk about it.

Star-more L hybrid changes and highlights

The appearance is even more

Sense of technology

The appearance of the hybrid version is very different from the fuel version. In order to highlight the identity of new energy, the central network has been replaced by a more technologically advanced suspension shape, and led strip decoration has been added on both sides of the grille. From a distance, it has the characteristics of a new energy vehicle, and I guess most people will see it as an electric car at first glance.

The front face is the biggest change in appearance, but there are a lot of people who complain that it's not good. And there is the magnificent atmosphere of the fuel version first, and this change of hybrid is difficult to get used to. But it is also undeniable that it is still very scientific and innovative.

The side and rear of the car have basically not changed, and the obvious is the semi-enclosed low-wind resistance wheel hub, which can not only play a role in reducing energy consumption, but also in line with the overall scientific and technological style.

New hybrid platform

The new car features Geely's latest RayTheon Hi· X intelligent hybrid platform is a special platform for hybrid vehicles, and is not changed from the fuel vehicle platform. The biggest advantage is that the additional motor, battery, and different transmission arrangement spaces are taken into account in advance.

Speaking of the Star-Yue L Hybrid, the previous fuel version was 2.0T, which required burning No. 95 gasoline. Now it is replaced by a 1.5T engine dedicated to hybrids, and it can be burned with No. 92 gasoline. According to the current oil price, it can still save a lot of money.

Space, interior

It's good

Although the hybrid version has a new platform, the body size and wheelbase have not changed, the space is basically the same as the fuel version, and the rear row and storage space are sufficient. In addition, the hybrid version currently has only two wheels, so the ground at the foot of the rear row is as almost flat as the fuel version of the two-wheel drive.

However, the floor of the fuel version of the four-wheel drive is very high, so the hybrid version of the four-wheel drive launched in the future will inevitably not be worried.

The interior and fuel version are the same, and the large screen through the central control has a strong sense of technology, but the hybrid version debuted the Geely Galaxy OS 1.3 system. Added functions such as co-driver cinema mode, call split screen, one-click zeroing task manager and OTA 2.2 technology application. These new features should also be updated on the fuel version in the future.

What is the level of hybrid technology?

Thor Hi · The X hybrid system belongs to HEV, that is, unplugged hybrid. It consists of a 1.5T hybrid engine, two motors and a three-speed hybrid transmission.

Hybrid engines are the most thermally efficient

Among them, the highlights of the 1.5T engine are: high-pressure direct injection, so that gasoline combustion is more full; supercharged intercooling, which can reduce the load of the engine; Miller cycle, improve the efficiency of the engine; low-pressure EGR system, optimize the thermal efficiency of the engine. The combined effect is that the thermal efficiency of this engine is as high as 43.32%!

It is currently the most thermally efficient hybrid engine, surpassing Honda and BYD, and the benefit is that every liter of gasoline can be used to the fullest. While achieving maximum performance, it is also more fuel-efficient, mainly reducing fuel consumption.

The motor optimizes engine performance

The Thor Hybrid is equipped with two motors, the P1 motor is connected to the engine and is mainly used to generate electricity, and the P2 motor is responsible for driving the vehicle.

Among them, the P1 motor has greater advantages over the common P0 motor (48V light hybrid BSG motor). The P1 motor not only generates electricity, but also has the role of the start-stop motor, in contrast, which can make the engine start more smoothly.

Therefore, although this 1.5T engine is a three-cylinder, relying on the P1 motor, it can improve the low-speed range with the most serious jitter, and after the speed goes up, in fact, the three-cylinder is not at all more shaky than the four-cylinder.

Moreover, the three-cylinder engine is generally more serious in the case of low speed, starting acceleration, and rapid acceleration. From the working logic of the hybrid system, there is no idle speed in parking, and the start depends on the motor, which can easily avoid some working conditions, so the mixed use of three-cylinder engines is actually more appropriate.

The first three-speed hybrid transmission

The core technology of the Thor hybrid system is the world's first mass-produced three-speed hybrid transmission, which not only realizes pure electricity, series and parallel modes, but also optimizes the logic of the three modes, with lower fuel consumption and stronger power.

Pure electric mode is when the vehicle is driven individually by a P2 motor for starting or small throttle acceleration. The series mode is whether the engine charges the battery pack through the P1 motor or the P2 motor drives the vehicle, mainly for urban conditions. In parallel mode, the engine also drives the vehicle, with the electric motor as an aid for high-speed operation or large throttle refueling.

Wide power delivery

Overall more fuel efficient

Thanks to the three-speed transmission, the parallel mode of the direct drive of the engine can be turned on at full speed at more than 20km/h, compared with Honda's i-MMD of more than 80km/h and BYD's DM-i of more than 70km/h. The advantage is that the acceleration at low speeds is more powerful, and it even gives it the ability to start ejecting.

This transmission is also different from the logic of the traditional gearbox to change the gear ratio, it is more like a central computer, according to different working conditions intelligently adjust the output power of the engine and motor and maintain energy balance. Keep the engine in the optimal output range at all times, so as to achieve fuel savings.

Compare the advantages and disadvantages of DM-i

Thor hybrid

Lower fuel consumption at high speeds

The function of BYD DM-i and Thor Hybrid is basically similar, and there are three modes of pure electricity and string and parallel, the working principle is basically the same, and the main feature is also fuel saving.

Referring to competitors, the official feeder fuel consumption of the Song PLUS DM-i 110KM version is 4.5L, and the comprehensive fuel consumption of the NEDC of the Xingyue L Hybrid Version is 4.3L. Although the official fuel consumption is generally not allowed, it can also be used as a reference.

DM-i fuel consumption is slightly higher because it has only one gear, the engine participates in the driving range is very small, only in the state of rapid acceleration and high speed can participate in the drive, but the engine load will be very high at this time. For example, when I drive dm-i to 110km/h or even higher, the engine speed is very high, the noise is also very large, and the apparent fuel consumption will increase significantly.

Because the Thor Hybrid has a three-speed transmission, it can greatly improve the range in which the engine participates in the drive, and more than 20km/h can enter the parallel mode, while the DM-i should be more than 70km/h. The advantage is that the engine can maintain a highly efficient working range while being involved in driving the vehicle earlier. Therefore, the comprehensive power is stronger, and the high-speed working conditions and sharp acceleration are more fuel-efficient than DM-i.

From the comprehensive performance point of view, geely's Thor hybrid compared to DM-i's advantage is mainly fuel saving. It may not save much from the data, but that is a comprehensive performance. If your car scene is mainly high-speed, the fuel consumption gap between the two will be more obvious.

BYD DM-i

Safer and more reliable

The disadvantages of BYD DM-i are mainly in high-speed conditions, and the gap between urban driving and urban driving will not be too large. And compared to Raytheon hybrid complex three-speed transmissions, DM-i's system is simpler and more reliable. Indeed, DM-i currently has no serious failures with respect to hybrid systems.

Regarding the hybrid system, safety is also a concern for everyone. BYD's DM-i system uses blade batteries that are known for safety, which is indeed better in safety than other lithium iron phosphate batteries and ternary lithium batteries. I have seen on-site puncture experiments at BYD's headquarters, and the blade battery is much safer than the ternary lithium battery in a short period of time after being damaged.

There is a pure electric mileage, which can be green carded

BYD DM-i is a plug-in hybrid, with the ability of pure electric driving and external charging, with a certain pure electric mileage, so most parts of the country can be green card. The Thor Hybrid does not have pure electric mileage and cannot be on the green card, so if there are charging conditions at home, the purchase conditions of DM-i are broader and the cost of use is lower.

How about comparing song PLUS DM-i?

Each has its own advantages

The configuration is very rich

The Star-Etsu L Hybrid Edition has two configurations, priced at 17.17 and 183,700 respectively, and the main opponent is the 110KM version of the Song PLUS DM-i, which also has two configurations, priced at 165,800 and 175,800. From the price side, we compare the low match of the former to the high match of the latter, because their difference is the smallest, only 4,000 yuan, to see who has the higher cost performance?

Both cars are very well equipped. From the perspective of differences, the use experience of the Hoshigoku L Hybrid Edition is better, such as the induction trunk, seat waist support, seat memory, matrix headlights, and 540-degree transparent chassis, all of which are further advanced on the basis of existing functions, and the experience is more advantageous.

Song PLUS DM-i has richer functions, such as parallel assist, steep slope slow descent, NFC key, vehicle air purifier, mobile power station, remote control driving, etc., daily use is more convenient, more functions, and more advantageous quantity.

Star-cross L hybrid

Size and space are bigger

Although the two cars are compact SUV, but the overall size and internal space have the performance of the level, then the specific who is bigger, or who is more practical, let's first look at the size.

From a size point of view, the Star-Over L Hybrid has obvious advantages in length and wheelbase. The interior space also has some advantages over the Song PLUS DM-i, mainly that the rear leg space of the Star Yue L Hybrid is more generous, the seat cushion is slightly longer, and the riding experience is better.

Song PLUS DM-i is available for pure electric commuting

In terms of use, Song PLUS DM-i has a pure electric mileage of 110 kilometers, if the home has the conditions to charge, the urban commute, a day of charging is basically enough. But there is no charging condition, Geely's comprehensive performance is also good, and there is no need to carry a large battery all the time, no extra baggage.

Write to the end

The main advantage of the Thor Hybrid Edition is that it is indeed more fuel-efficient in high-speed and high-load conditions. But most people are actually mainly commuting in the city, so in this case, as long as you don't start with full throttle every time, it doesn't have much advantage over the fuel consumption of DM-i. So it still depends on the specific use case.

As for the stability that everyone is worried about, Thor Hybrid can be said to be one of the most complex hybrid systems at present, and it has not been tested by the market just listed, and it really needs to be verified.
