If you know what "thick accumulation and thin hair" is, you will probably understand why Trumpchi dares to claim that he can build the strongest hybrid technology platform in China.
Trumpchi can be said to be the earliest Chinese brand in China to explore a variety of hybrid technology routes.
In 2009, when many Chinese brands were still in the stage of ignorance of imitation, Trumpchi officially launched the development of the first hybrid model, and soon launched a hybrid model based on the P1+P4 configuration, and launched 200 vehicles to the society for demonstration operation.
Five years later, in 2014, Trumpchi officially launched the first range-extending electric vehicle in China, the GA5 REV.
The power is only 13kWh OF GA5 REV, pure electric endurance can reach 50km, and the comprehensive fuel consumption of 100 kilometers under NEDC conditions is only 2.4L, which is not bad now. Most importantly, its price was not expensive at the time, and a B-class PHEV only started at 199,300. At that time, Roewe also had a B-class PHEV of the same size, but the starting price was almost 240,000.
Until now, you can still see the pioneer of domestic extended-range electric vehicles on the road, which shows that its quality is not bad.
In 2017, just three years later, Trumpchi continued to upgrade its hybrid system from a simple range extender to a more complex, parallel parallel type currently used by most Chinese brands, and matched it with a hybrid-specific engine, the 1.5L Atkinson cycle engine.
Compared with the simple range extender, the series parallel type can allow the engine to intervene in the drive under the right working conditions, so the efficiency and power will be stronger. The comprehensive fuel consumption of the GA3S PHEV equipped with this hybrid system is only 1.4L under the NEDC working conditions, and the measured "zero hundred acceleration" time of the vehicle is 8.9s, and the acceleration time of 0-50km/h is not more than 4s.
This system, which Trumpchi calls GMC 1.0.
The so-called "G" is the first letter of GAC GAC; "MC", that is, Mechatronic Coupling, translates to electromechanical coupling system. In fact, whether it is Toyota's THS or Honda's i-MMD, the same is an electromechanical coupling system, but the name is different.
Electromechanical coupling system, the name is very simple, but the gold content is not low at all. It is said that there were no more than 5 car companies with this technology in the world at that time.
Although this is the technology of five years ago — in 2017, the GS4 PHEV and GA3S PHEV equipped with this technology were already on the market at the same time, so the development time is estimated to be pushed forward a few years - but now it is not outdated at all. After all, the hybrid system of some of the popular brands and its structural principles are extremely similar.
GMC1.0 mass production program
In July 2014, GAC motor's first-generation GMC patent scheme
At the beginning of 2020, Trumpchi upgraded this set of GMC 1.0, upgrading the original 1.5L ATK to a 1.5T turbocharged engine, making it more efficient, more powerful, and more widely used, even in the face of continuous full load output in the face of power shortages.
If I remember correctly, the GS4 PHEV equipped with this system is the first Chinese brand plug-in hybrid model that dares to announce its low power consumption. At that time, most PHEV on the market was still carrying the insult of "a dragon with electricity, a worm without electricity" - everything is good when there is electricity, and everything is not good when there is no electricity.
Although the GS4 PHEV has been on the market for almost two years, its 4.6L/100km of power consumption is still the top level in the industry, and now equipped with DM-i hybrid technology, the same as the compact SUV Song Pro, Song PLUS is almost the same.
When seeing BYD's PHEV so big, many people are lamenting that Trumpchi, who has a deep foundation in hybrid technology, may miss the window period of the market and catch up early in the evening. But no way, Trumpchi is an idealist, after the launch of the 2020 GS4 PHEV, he is still thinking about a better configuration of the hybrid special transmission.
To this end, Trumpchi has partnered with a number of consulting firms in Europe to analyze the possible configurations of hybrid transmissions one by one. This is not a simple task, because there are more than 193,000 configurations, which not only consumes a lot of manpower and material resources, but also consumes a lot of very valuable time - more than six months.
So far, Trumpchi's hybrid technology route is the most diverse in China: both Toyota THS power shunt type, and self-developed double-stop series parallel and single-stop series parallel type, and previously also did the range extender and P1+ P4 parallel type. It can be said that there is no hybrid technology route, trumpchi has not played.
This set of GMC 2.0 has strong compatibility, can be made into HEV, PHEV, but also can be made into a program extender.
From more than 193,000 configurations, Trumpchi finally chose a hybrid special gearbox with a two-stop series parallel configuration, which is the GMC 2.0 we see now.
Compared with Honda's i-MMD and BYD's super hybrid DM-i, Trumpchi has one more gear, which makes it easier for the engine in the efficient work area to intervene in the drive, so that the energy consumption of the whole vehicle is lower and the power is stronger; compared with the Great Wall Lemon DHT, which is also a two-gear structure, Trumpchi's shift mechanism adopts the FORM of AT, and the shift action is more supple.
It is reported that the configuration of GMC 2.0 is highly similar to the latest generation of a joint venture car company. It can be said that if you buy a Trumpchi car that adopts GMC 2.0, you are actually using the money of domestic cars to buy the next generation of joint venture car companies, and enjoy a stronger and smoother power one step ahead. It's very rare! How could you have imagined that in terms of drive systems, Chinese brands are actually ahead of foreign brands.
In fact, GMC 2.0 has been officially released as early as the 2019 Guangzhou Auto Show, and the reason why it has not been mass-produced until now is because of Trumpchi's idealism - we must pay close attention to quality. Therefore, they have repeatedly verified GMC 2.0: after 100,000 hours of bench testing, they also carried out an equivalent verification of nearly 10 million kilometers on the actual vehicle.
Trumpchi Hybrid is the first car company to have two hybrid systems.
Regarding GMC 2.0, I think you still have a lot of questions.
For example, why do many of the current hybrid systems only use 1.5L engines, while Trumpchi start with 2.0L engines? What is the secret to the efficiency of GMC 2.0? Why is it possible to achieve a fuel consumption of 3.6L/100km for an A-Class car? Of course, the most important thing is, how does the first Shadow Leopard HEV equipped with GMC 2.0 actually open?
In order to learn more about Trumpchi GMC 2.0, we came to the GAC Research Institute and had a dialogue with Qi Hongzhong, deputy director of the Powertrain Technology R&D Center, for several hours to uncover some of the little-known secrets of Trumpchi GMC 2.0.
