In the past two years, the Chinese brand hybrid system can be called a collective explosion, BYD's DM-i, Chang'an's blue whale iDD, Great Wall's lemon hybrid DHT, Chery's Kunpeng DHT, Geely's Lei Shen Zhi Qing Hi · X's five self-owned brand hybrid systems were all unveiled on the market. There is also GAC Trumpchi, not only directly using Toyota's THS hybrid system on the new generation GS8, but also the self-developed GMC 2.0 hybrid system is also about to be involved in this war.
So whether the autonomous hybrid system will work in the end, and will the fuel consumption level, performance performance, and use experience be pulled down in front of the Japanese double male? Recently, we got this newly listed Star Yue L hybrid version, to compare with Shuangtian, and tell you with actual measurement data.
Why pick the auspicious star more than L Thor to compare? In fact, purely because we just got this car recently, the follow-up has gathered all the self-owned brand hybrid models, we will also directly do a horizontal review, so stay tuned.
01
Fuel consumption test
Highway conditions + city traffic conditions
Hybrid models are most concerned about fuel consumption. But whenever you have a friend who drives a Toyota twin engine or a Honda hybrid around you, you will definitely be shown by their fuel consumption level, and the more the oil price rises, the more envious and jealous the feelings of envy and hatred are.
So let's start with fuel consumption performance. The fuel consumption level of Haoying Hybrid and Veranda Dual Engine must have been heard of, and the hundred kilometers is about five or six oils, which is half lower than the fuel version. Then the actual fuel consumption level of this Geely Star Yue L Thor Hybrid Version has become the point we are most looking forward to.
Why add oil to a slight overflow? Because the timing of the oil gun jump gun is affected by many factors, the full tank mouth can minimize the error caused by the early jump gun. After the test, the overflow is added again, which is the actual fuel consumption, which calculates the average fuel consumption.
During the test, the three cars in the premise of maintaining a safe distance, as far as possible with the car to ensure that the road conditions are the same, the air conditioning of the three cars is uniformly set to 22 degrees / second wind / cooling / internal circulation throughout the whole process, the three drivers will also rotate with each other, to avoid the impact of different personal driving styles.
After a full 230 kilometers of driving, of which the total mileage of toll highways exceeds 220 kilometers, in addition to queuing in and out of toll stations, replacing people in the service area, and slowing down in road construction, the whole process is running against the speed limit. At the end of the high-speed test, we returned to the gas station at the time of departure, with an average speed of about 70km/h during the whole journey.
It can be seen that the fuel consumption of the Star-Over L Thor and Veranda dual-engine watches is 5.4L/100km, while the Haoying hybrid is 6.4L/100km. It seems that Honda is a little more expensive than the other two?
In addition, we can also find that there is a little difference in the subtotal mileage of the three cars, in fact, there will be a small discrepancy between different vehicles, between the apparent and the real mileage, we take the average of the three vehicles to calculate, take 231.1 km as the total mileage of fuel consumption.
Refill the three vehicles with fuel until the tank mouth overflows, and finally the actual refueling volume and actual fuel consumption of the three vehicles are as follows:
We then began fuel consumption testing of low-speed roads in the city. The test method is consistent with the previous highway conditions, but it is a different road environment, driving through an ordinary urban road of 106.0km (three vehicles average), the whole process is stop-and-go, there are many intersections of cars, and the average speed is only 29km/h.
Willanda city traffic fuel consumption is only 4.3 liters? Star Yue L is at the bottom, it seems that Toyota dual engine technology is reliable, high speed and city are fuel saving, but is this really the case? Let's first look at the actual amount of refueling.
Fill up the oil again until it overflows, and the actual fuel volume and real fuel consumption of the three vehicles are as follows:
We analyzed the fuel consumption performance of the three vehicles, the honda with the engine direct drive at high speed, in this long-term cruising at 120 hours, is basically equivalent to a gasoline car, because its 2.0L engine is weaker, it needs a higher speed to maintain speed, and without the assistance of the motor, the fuel saving effect is slightly worse.
Geely's Thor hybrid system can also achieve direct engine drive at high speed, but thanks to the 3-speed transmission system, Geely can change the gear ratio to keep the engine in the best efficiency state as possible, and this three-cylinder 1.5T engine, Geely is known for its thermal efficiency reaching the world's highest 43.32%! It is difficult to say whether it is really so high, but the high speed is indeed quite fuel-efficient.
In the low-speed road conditions of the city, due to the need for frequent starting acceleration, the body weight is 100 kilograms more than the other two cars, the Star Yue L Raytheon, the power consumption and fuel consumption will also be slightly reduced. Among the three cars, Haoying, the most powerful motor, is easier in this low-speed working condition, and the fuel consumption is more advantageous. The performance of the Veranda dual engine is exactly in the middle of the two.
Finally, it must be explained that this fuel consumption comparison test is not a completely rigorous scientific experiment, and errors cannot be completely avoided, so the results of the test are only for your reference.
02
0-100km/h acceleration test
After measuring the fuel consumption data, let's look at the performance data.
The three cars are two-wheel drive versions, their power parameters are as follows, from the comprehensive performance of the hybrid system, the three cars among the star more L Thor data is the strongest, Veranda is the weakest.
So the most beautiful data must be the fastest acceleration?
We accelerated the three vehicles under the same environmental conditions, turned off the ESP and air conditioning before the test, and turned on the sport mode.
Hoshigoku L Raytheon has a DHT Pro three-speed transmission, which can use the large speed ratio of 1 gear to achieve catapult start, and the starting tire will last about 2 seconds, and the torque output is quite powerful. Although the book data is the strongest, it is also the heaviest, and the acceleration performance is the lowest among the three cars. The measured zero hundred score of 8.21 seconds is still relatively close to the official acceleration score of 7.9 seconds, and there is a gap between the physical object and the packaging map, but it is not false propaganda.
Honda's official acceleration results have always been relatively low-key, such as the official Zero Hundred Score 8.6 seconds civic, measured 7 seconds can break the hundred. The official acceleration of Haoying Hybrid is 9.1 seconds, while we measured it to be 8.15 seconds, which is modest again.
Veranda, which seems to have the least advantage in book data, once again taught us that data does not represent strength, and ran a 7.95-second acceleration performance, faster than the other two cars.
But then again, in fact, the acceleration performance of the three cars is not different, they are all 8 seconds level, the fastest Veranda is only 0.26 seconds faster than the slowest Star Yue L, with the limited perception ability of humans, it is impossible to detect this small speed difference. On the contrary, the Veranda engine was too noisy, roaring all the way, and it felt as if it was a century slower than the star-vietnam L.
03
100km/h-0 brake test
In terms of braking performance, we also routinely carried out a 100km/h speed brake stop distance test, and all three cars adopted the braking system of the solid disc after the front ventilation disc, of which The Star Over L and Haoying both used 235mm width tires, and Willanda used 225mm tires, and the mileage was longer, which was relatively inferior. In addition, the hoshigoku L Thor's empty car weighs 1785kg, the heaviest of the three vehicles, followed by Haoying Hybrid 1689kg, and finally Velanda Twin Engine 1660kg.
In the actual test process, the three cars were relatively stable when braking at full force, and there was no particularly obvious rocking. In terms of physical sensation, the braking force of The Velanda is indeed inferior to that of the other two cars, and the Hoshikoshi L has a stronger sense of dragging. Judging from the body posture, the hoshikoshi L's front is also more obviously sunken, and the rear of the car is high and cocked. This exaggerated posture, in addition to the braking system to give force, and the Star-More L Raytheon power battery placed under the middle passage of the front seats, resulting in the vehicle's center of gravity to the front also has a certain relationship.
In general, the performance of the three cars is relatively close, and they have achieved braking within 40 meters, of which the Star Yue L, as the heaviest of the three cars, is worthy of recognition, and the Relatively Inferior Willanda with the tires is also slightly better than Haoying.
04
Noise test
Noise performance is also a topic point for hybrid models, when in EV mode, the engine is turned off, the whole car is as quiet as an electric car, and the test at this time is the body's isolation level from wind noise and tire noise. When the engine intervenes and accelerates sharply, the running noise and sound texture of the engine are fully displayed.
Among the three cars, Haoying and Xingyue L are equipped with active noise reduction, Xingyue L is equipped with front windshield and front soundproof glass, and independent brands are always so willing to pay attention to the cost, and this joint venture model is really incomparable.
We tested the noise values of the three models under the following six working conditions, and before the noise test, we ensured that the air conditioning and audio of the three cars were completely turned off, the same noise meter was used, and the test was carried out on the same closed road. The measured data are as follows:
It can be seen from the measured data in the above table that in the state of vehicle stationary and engine shutdown, the noise value of the star-vietnam L Raytheon and Haoying hybrid in the car is very low, only 33+ decibels, which is significantly better than the Veranda dual engine. When the engine starts, haoying hybrid has the highest operating noise, and the star-vietnam L Raytheon is the lowest, with a difference of 6.7 decibels.
At 60km/h, when the vehicle is in EV mode, Haoying is 3.9 decibels higher than The Star L, while Willanda is slightly 0.7 decibels higher than Haoying.
At 60km/h, the floor oil is stepped on, so that the engine is running at full load, at this time, the noise value of the Hoshigoe L is 62.7 decibels, the Wilanda is a full 10 decibels higher than the StarR, and the Haoying is slightly 0.3 decibels higher than the Willanda.
From the subjective feeling point of view, The Wilanda Twin Engine is the most noisy one, but from the measured data, the two fields are actually comparable, but because of Toyota's 2.5L Atkinson cycle engine, when running at high load, the sound texture is too thin and hoarse, but from the measured data, Haoying in some working conditions, the noise is actually a little greater than That of Wilanda.
05
Three-car hybrid logic difference
Geely's Lei Shen Zhi Qing hybrid system can be said to have paid considerable attention to recently, and the hybrid system of several major Chinese brands is based on the development of 1.5T engines. Haoying uses a 2.0L self-priming engine and a third-generation i-MMD hybrid system, while the Veranda Dual Engine is a fourth-generation THS system based on a 2.5L automatic engine.
To briefly summarize the three-car hybrid system, their core concept is the same, they are equipped with a very high thermal efficiency engine, and then use the motor to make up for the lack of low engine torque, so that the engine can be operated at the best efficiency as possible.
Geely's set of Thor hybrid system, the logic is more similar to Honda's i-MMD, the medium and low speed belongs to the range-extended mode, the engine only generates electricity, and the vehicle's drive is completed by a high-horsepower drive motor, so the two cars drive closer to the electric vehicle, with a very smooth acceleration feeling.
When the speed of Haoying Hybrid reaches more than 80km/h, the wheels can be driven directly by the engine. One of the core highlights of the Geely Ray Smart Engine Hybrid System is the world's first mass-produced 3-speed hybrid transmission DHT Pro.
Simply put, it has two more sets of planetary gears than Honda (Honda only has a clutch without planetary gears, Toyota has a set of planetary gears but no clutch), so as to achieve three-speed shifting, further improve fuel efficiency, and the range of engine direct drive is also wider, starting from 20km/h.
Unlike Honda and Geely, which are two models that prioritize motor drive, Toyota's THS dual-engine hybrid system is dominated by a 2.5L Atkinson cycle engine, which regulates the load of the engine through an E-CVT transmission composed of dual motors + planetary gears, and the engine is always connected to the E-CVT and will not drive the vehicle alone. Motors are more likely to play an auxiliary role.
06
Static reviews
Finally, let's briefly comment on the differences between the three cars from the static point of view.
These three cars are actually very localized in China, GAC Toyota's Velanda is from the global model RAV4 shell, GAC Honda's Haoying is derived from CR-V, these two cars in the styling design belong to China's special supply. Geely Xingyue L is not to mention, pure Chinese brand models, with the family characteristics of the Geely brand.
Relatively speaking, the hybrid version of Veranda and Haoying does not have any exclusive design, weakening its new energy identity. The front face of the Thor Hybrid Edition has been redesigned to make it look like a new energy vehicle at a glance, and the exclusive color of the Hybrid Edition of "Morning Dew White" has also been added.
Coming to the car, the central control design beauty and ugliness aside, in terms of texture and configuration, Xingyue L Raytheon still has certain advantages for the other two, and the joint venture brand is indeed difficult to match with the independent brand in this regard.
In addition, in terms of space, since the size and wheelbase of hoshikoshi L are obviously larger than the other two, we do not intend to directly compare the ride space of the three cars, and only discuss the impact of the power battery layout on the occupant compartment of the car.
The Star-Etsu L is produced from the CMA platform, which is known to have been jointly developed by Geely and Volvo, so the power battery of the Star-More L, like Volvo's new energy vehicles, is tucked into the position below the middle passage of the front seats. This layout is very clever, making full use of the spatial structure, but because the position is relatively front, so that the core power components are all concentrated in the front half of the body, the weight distribution of the whole vehicle is somewhat top-heavy, which affects the dynamic limit to a certain extent.
Most of Toyota's dual-engine models have power batteries placed under the rear seat cushions, and so is The Veranda. This layout has almost no impact on the ride and loading space in the car, but the battery heat dissipation port is located at the foot of the rear passenger, and occasionally emits hot air (the temperature is not high), which affects the ride comfort to a certain extent.
Haoying's power battery was placed in the trunk, which squeezed out the space originally used to store the spare tire, so the hybrid version of Haoying eliminated the spare tire and equipped with a explosion-proof tire. In fact, the frequency of use of the spare tire is extremely low, and now more and more models are abandoning the spare tire, Haoying's battery layout does not affect the crew compartment, but also makes the vehicle weight distribution more balanced, personally think it is more practical.
07
Summary
Is the strength of the Gilly Thor Hybrid enough to challenge the Shuangtian Hybrid? Throughout the text, the answer is already obvious. From the technical content, fuel consumption performance, performance performance, driving quality, space layout and other aspects, Geely's Lei Shen Zhi Qing hybrid system has done better, even better than Shuangtian. The rise of Chinese brands is very exciting, but it must be recognized that Toyota and Honda, as joint venture brands, are still more appealing than Geely, especially in the hybrid technology they have been deeply engaged in for many years, and their maturity and reliability have been verified by the market, which is currently unattainable by Geely. But it doesn't matter, the road is long and the road is long. BYD's DM-i can become popular, indicating that consumers recognize the hybrid products of our Chinese brand, and the Geely Raytheon hybrid system will undoubtedly be another dark horse.
