The finale of the julang hybrid is unveiled

Energy conservation and emission reduction have become a tight curse hanging over the head of every car company, and Chinese and foreign enterprises are without exception.

Under the stick of policy, car companies invariably regard pure electric routes as the preferred solution for energy conservation and emission reduction. However, pure electric products still have limitations, and the problems of insufficient mileage and difficult charging still need to be solved.

The new energy development route of technological diversification and energy diversification has become the trend of the times. There is no need to install charging infrastructure, there is little change in user driving habits, there is no mileage anxiety, and the power reliability is strong under extreme conditions such as high temperature and high cold, which can meet the needs of users in different regions, and hybrid technology with these advantages stands out.

Policy orientation also proves this. In 2020, under the guidance of the Ministry of Industry and Information Technology and the Society of Automotive Engineers of China taking the lead in organizing the preparation of the "Technology Roadmap 2.0", the expert group unanimously agreed that hybridization is a better development path to achieve the double carbon target in the next 10-15 years, and is one of the key technologies for future energy conservation and emission reduction, and pointed out that by 2035, the mainland should fully realize hybridization.

In this context, the independent leading enterprises that keep up with the wind direction have released a new generation of hybrid systems in 2021, including Great Wall Motor's new lemon DHT system, Chery Automobile's Chery Kunpeng DH system, Geely Automobile's new Leishen hybrid system, BYD DM-i series super hybrid, Changan Automobile's Blue Whale iDD hybrid system, Dongfeng Motor's Mach power MHD hybrid system, and GAC Group's "Green Engine Technology".

On the occasion of the Chinese brand group to make a hybrid, GAC Trumpchi officially released the brand name of the hybrid technology on April 26 - Julang Hybrid. So far, GAC Trumpchi Julang Hybrid has two hybrid technology routes, realizing "dual-track parallelism": both GMC series parallel hybrid system and THS power shunt hybrid system.

So far, Trumpchi has not only provided consumers with more choices, but also double insurance for their own hybrid future. On the same day, as the first SUV of Julang Hybrid GMC2.0, the future technology pioneer Yingku also officially debuted.

One or two hybrid technology routes to create the strongest hybrid technology platform

Julang hybrid is GAC Trumpchi's deep insight into the needs of market users, and it is also the accumulation of technology for many years.

As early as 2009, GAC Group has laid out "hybridization", and has accumulated more than 10 years of development experience so far, and is one of the earliest independent brands in China to carry out the development and exploration of a variety of hybrid technologies.

In 2017, GAC Trumpchi took the lead in completing the development and mass production of domestic dual-motor series parallel DHT, breaking the technical blockade of international giants, and successively put four models such as GA5 REV and GS4 PHEV on the market. What is more worth mentioning is that GAC Trumpchi also opened the first domestic hybrid technology output joint venture, and Trumpchi GS4 PHEV was imported into GAC Mitsubishi in reverse.

In addition to the self-developed system, GAC Trumpchi has introduced Toyota's new fourth-generation THS hybrid system. For Toyota, GAC has a deep accumulation in the field of hybrids and a strong self-research strength, which is undoubtedly a reliable partner. In addition, in the past few decades, in the process of gac toyota's rapid growth, GAC and Toyota have completed the initial run-in, and there is more tacit understanding and trust between each other, and GAC has become the most suitable choice for Toyota at this time.

The new second-generation GS8 Dual Engine Series is equipped with GAC 2.0TM engine and Toyota's fourth-generation THS hybrid system, which realizes the combination of power in the field of hybridization. Since its listing at the end of 2021, orders have continued to climb, ranking first in the sales of 200,000 yuan Chinese hybrid SUVs in the first quarter of this year.

At the time of the turbulence of the hybrid market, the rapid production of market-proven products and the erection of two extremely offensive machine guns in the trenches of war, behind this is the accurate grasp of the market wind direction, forward-looking layout, and the deep accumulation of technology, which is the ambition of the hybrid market.

At the same time, competing with Toyota Hybrid Technology shows that GAC Trumpchi has great confidence in the self-developed hybrid technology, and has the strength to face the joint venture brand, and the Chinese brand is rising.

Second, the technology is all-round, GMC opened the curtain of Trumpchi self-developed hybrid

In 2022, oil prices are on people's nerves.

In 5 months, oil prices rose 6 times, and even broke 9 at one point. As oil prices rise, consumers begin to switch to new powertrains, and not only is the pure electric market heating up, but the hybrid market is also beginning to explode. The data shows that in March 2022, the wholesale of ordinary hybrid models was 74,625 units, an increase of 62% year-on-year and 32% month-on-month.

If the new second-generation GS8 dual engine series is the first manifestation of the power of close cooperation between GAC Trumpchi and Toyota, then the first GMC hybrid new model Yingku unveiled this time is a proof of GAC Trumpchi's own strength.

GMC hybrid system adopts series parallel configuration, with "high quality, low fuel consumption, strong power, quieter, super smooth" five major advantages; strong compatibility, can cover HEV, PHEV, REEV, and even hydrogen mixed and other models, to meet the needs of users in all scenarios, with the strongest engine, the most intelligent electromechanical coupling, the most efficient battery.

GMC Hybrid System is equipped with GAC 2.0ATK high-efficiency Atkinson engine for the first time, using GAC GCCS efficient combustion system, low-friction design, exhaust gas recirculation system, intelligent thermal management and noise reduction design, is a hybrid special engine, the maximum thermal efficiency under the actual user conditions is 42.1%.

In the composition of the power system, the fuel vehicle is the gearbox and the engine, while the hybrid vehicle is the engine and the electromechanical coupling system, and the electromechanical coupling system is to couple or divert the power of the engine and the motor, which is not a concept with the gearbox.

Compared with the mainstream hybrid system on the market at present, the second-generation electromechanical coupling system of Trumpchi GMC has one more gear, and the setting of 2 gears is mainly to optimize the working point of the engine at each speed, while expanding the speed range of the direct drive of the engine to reduce fuel consumption, and improve the output torque from the engine to the wheel end, optimize the NVH performance, cover all working conditions, and achieve lower energy consumption and stronger power of the whole vehicle.

Compared with other hybrid systems with the same two-stop structure, the shift of trumpchi GMC's second-generation electromechanical coupling system adopts the form of AT, and the shifting action is more smooth. Because the drive motor maintains the wheel end output at the same time, combined with the front generator for speed regulation, the combined speed difference is small, the clutch is used instead of the synchronizer, and there is no shift impact, so it is extremely smooth.

In addition, the battery cooling system adopts the same high-efficiency refrigerant direct cooling technology as BMW luxury cars, which achieves all-weather high-efficiency and high-power output of 10 seconds peak discharge power of more than 70kW, thereby achieving excellent vehicle acceleration performance, compared with the same level of hybrid models Fuel consumption is lower.

In 2022, GAC Trumpchi will launch hybrid models of Yingku, Yingbao and M8. Relying on the unique dual-hybrid technology route, GAC Trumpchi expressed confidence in building the brand into China's hybrid NO.1 and becoming the leader of China's hybrid. It can be expected that with new power, new technology and new products, GAC Trumpchi is entering the next "golden decade".
