On December 15, Great Wall Motors officially released the "Lemon Hybrid DHT" technology for full speed range and all scenarios. "Lemon Hybrid DHT" is completely independently designed and developed by Great Wall Motors and has completely independent intellectual property rights. It has a total of 199 patents, including 80 core patents.
Its arrival means that domestic brands have broken the monopoly of joint venture brands in the hybrid field for many years, strengthening people's confidence in independent research and development.
One day after the press conference, Great Wall also specially arranged a test drive at a venue to let us find out the details of the Lemon Hybrid DHT. Since this was a field test drive and the vehicle was also trial-assembled, there were many limitations. The professor could only share his most intuitive feelings with everyone.
The appearance and interior of the trial car are not much different from the new generation Haval H6. The biggest difference is that it is equipped with a 1.5L DHT100 hybrid system with a maximum power of 140KW. The more powerful 1.5T has no chance to meet us this time.
Because it is a hybrid model, the vehicle computer system of the trial vehicle is also very "suitable", and the vehicle drive mode can be seen on the central control screen. In addition, there is a "single pedal" mode that is only available in many pure electric vehicles.
When the vehicle speed is below 30km/h, the vehicle is driven solely by pure electricity from the 1.8kWh battery. This can avoid the jitter caused by the engine at low speeds and bring a better driving experience.
When the speed is greater than 30km/h and less than 70km/h, the vehicle is driven by the engine. Since the gearbox is a fixed-axis gearbox and the adjustment is good enough, the movement when the engine intervenes is not obvious. .
When the speed is greater than 70km/h, the engine and motor are driven at the same time, bringing stronger power output. Lemon Hybrid DHT adopts a dual-motor system that is rare in domestic cars. One motor generates electricity and the other drives. They work together to achieve efficient output.
At the press conference, the leader of Great Wall's R&D department emphasized the four-character characteristics of this hybrid system, "fast, smooth, quiet, and economical." During the test drive at the venue, I really felt the "fast, smooth and quiet" of the lemon hybrid DHT, but I have no conditions to feel the "saving" for the time being.
The official conducted a bench test on the trial vehicle, and finally obtained a comprehensive fuel consumption of 4.6L/100km according to the working conditions calibrated by the Ministry of Industry and Information Technology. Generally speaking, the fuel economy of Great Wall's hybrid system is relatively outstanding. .
Perhaps many people still don’t know what Great Wall’s hybrid system means? In the past, when we mentioned hybrids, we often thought of Toyota. Toyota took the cake and set up technical barriers. Honda bypassed the shackles set by Toyota and took another path, adding another lock.
For domestic car companies that arrived late, it is very difficult to bypass these technical barriers. Whether it is difficult is one thing, whether it can be done is another. Fortunately, our Great Wall has broken through the technical barriers set by these joint venture car companies and found its own way. This enterprising spirit deserves encouragement.
Great Wall calls this hybrid system a two-speed hybrid. Officially, it claims that this hybrid can better balance performance and fuel consumption than power split (Toyota) and single-speed hybrid (Honda). . Judging from the test drive, the 1.5L has a power output comparable to the 1.5T. Great Wall's new hybrid does have two brushes.
Lemon Hybrid DHT adopts a dual-motor hybrid topology, which can realize various working modes such as EV driving, hybrid driving, series driving, energy recovery, idle shutdown, etc. It can realize various working modes through intelligent switching of the control system. The perfect balance between power and fuel consumption in driving scenarios.
With so many functions, the Lemon Hybrid DHT is not bloated, and its mechanical components are highly integrated. The "seven-in-one" high-efficiency multi-mode hybrid assembly integrates a 1.5L/1.5T hybrid-specific engine, dual power generation/drive motors, a fixed-axis gearbox, a dual-motor controller, and an integrated DCDC. The smaller the volume, the more technical difficulty The bigger.
In addition to supporting HEV, this system also supports PHEV. Great Wall has adopted the world's largest capacity battery pack for PHEV, and the model's NEDC cruising range can reach 200km.
Not only that, the system can be equipped with a P4 electric drive rear axle, and the total system power can reach 320kW, meeting the needs of some users for high-performance vehicles.
Faced with increasingly serious environmental problems, governments in many countries have introduced strict environmental protection policies. For the automobile industry, new energy vehicles will be the main focus in the future. At present, there are still some technical barriers to pure electric vehicles. Mature and stable hybrid models are undoubtedly a good direction for car companies.
The general direction is to develop new energy vehicles. Although ordinary people do not have so many choices, there is no need to be frustrated. After all, hybrid vehicles have many benefits for consumers.
Let’s put aside the practical issue of “tens of thousands more”. The lower fuel consumption of hybrid models is only the most obvious advantage. Many people who buy cars for the first time actually ignore the comfort and only focus on the superficial "fast and slow" driving experience. They only regret it when they become experienced drivers.
The hybrid model is a one-step solution to consumers' pain points. It has both good quietness and abundant power output. It can be said to be a very perfect model.
How about comparing it with Toyota and Honda models? Let's take the price factor into consideration first. Lemon hybrid DHT will definitely allow consumers to enjoy the dividends of hybrid models at a price much lower than that of Toyota and Honda models. This cannot be ignored.
Now we don’t have to compare the driving experience between Great Wall’s 1.5L hybrid and Toyota’s 2.5L hybrid, which are not of the same order of magnitude in themselves. We should look forward to the launch of more models under the lemon hybrid DHT system, and then the close comparison will be more interesting.
As the professor said at the beginning, Great Wall has developed this new hybrid system, which is something worthy of encouragement. Taking this opportunity, we hope that more domestic auto companies can innovate technologies, break through technological blockades, lead the development of China's auto industry, and bring better auto products to the Chinese people.
