The self-developed GMC 2.0 hybrid has good acceleration performance. GAC Trumpchi Shadowcool has three powertrains, namely the third-generation Julang Power 1.5TGDI engine + wet 7-speed dual-clutch gearbox, and the third-generation high-power 2.0 There are three types of power: TGDI engine + Aisin 8AT transmission (the power of the GS8 fuel version) and 2.0ATK Atkinson engine + GMC2.0 second-generation electromechanical coupling hybrid system. Launched first are the power combinations of 1.5T+7DCT and 2.0ATK+GMC.

Currently, GAC Trumpchi has two hybrid routes. One is the Toyota THS hybrid system on the GS8, which will also appear on the new Trumpchi M8 in the future. Another route is that Yingku and Yingbao are equipped with the self-developed GMC 2.0 system. So is the self-developed hybrid system reliable? In fact, the Trumpchi GS4 PHEV launched by GAC Trumpchi in 2017 pioneered the domestic dual-motor series-parallel DHT system. This system can be regarded as the GMC 1.0 system. The GMC 2.0 system launched this year adopts the latest technology and consists of a 2.0ATK (Atkinson cycle) engine, an integrated dual-motor two-speed DHT, a power ternary lithium battery, and a full-speed and full-field intelligent energy management strategy. .

The 2.0L Atkinson cycle engine of Yingku is a fourth-generation high-efficiency naturally aspirated engine independently developed by GAC. It adopts GCCS combustion control system, intelligent thermal management, exhaust gas recirculation, noise reduction design and other technologies. The highest thermal efficiency can reach 42.1%, higher than both Toyota and Honda.

The integrated dual-motor DHT adopts a two-speed structure. Compared with systems such as Honda i-MMD that use E-CVT, one more gear allows the engine to operate more efficiently and further improves fuel economy. The entire electromechanical coupling system of GMC 2.0 can achieve a hybrid system thermal efficiency utilization rate of ≥95.5% under WLTC operating conditions.

The GMC 2.0 system can realize five modes: pure electric, series (extended range) mode, parallel, direct drive, and energy recovery (the working principle is somewhat similar to Honda's i-MMD). Through the full-speed and full-field intelligent energy management strategy, The system can intervene and optimize the system working status in advance based on real-time traffic conditions, vehicle status and other information. For example, when the road is congested, the power plan can be adjusted in real time according to the degree of congestion to reduce engine intervention in congested conditions; it can also automatically identify the car-following status. Real-time adjustment of energy recovery intensity reduces the number of driver braking operations while improving driving experience and economy.

Finally, the 2.1 kwh ternary lithium battery adopts high-efficiency refrigerant direct cooling technology. The air-conditioning refrigerant is directly passed into the battery for direct cooling. In addition, it is a power battery. When the power is above 50%, it can output a peak discharge power of 70kW for 10 seconds. Compared with nickel-metal hydride batteries, it can bring better acceleration performance.

Speaking of acceleration performance, one of the on-site experience sessions of this Yingku is the 0-60km/h acceleration experience. The official claims that the Yingku Hybrid’s acceleration time in this speed range is 3.9 seconds. The actual acceleration time measured on site is around 4 seconds, and some even reach 3.9 seconds. If the battery is sufficient, the feeling of full acceleration is the same as that of an electric car. At the same time, the movement and noise when the engine is involved are better than those of Honda and Toyota. Hybrids are much smaller.

Yingku adopts the Momentum chassis, which is developed according to the three characteristics of "toughness, stability and smoothness". It uses dual hydraulic suspension and high-strength, high-damping swing arm bushings and high-performance shock absorber valve systems to achieve the vehicle's chassis toughness. Secondly, the filtration performance of the entire vehicle is improved and road noise is optimized by optimizing the layout of the shock absorbers and connecting the subframe bushings to the body.

In the field experience, Yingku drove on a special road with large undulations. From the outside of the car, the suspension showed a large swing. Fortunately, the suspension stroke was long. Sitting in the car, I felt that the swing of the body was not particularly large, and there was no As the body swings, there is an obvious "grasping for direction" situation, which gives people a very stable feeling. In addition, when driving on simulated speed bump road conditions, the suspension performance is comfortable enough, the vibration filtering effect is relatively thorough, and there is Q-bounce feedback that represents toughness. To put it bluntly, in order to please young people, this car has not completely smoothed out the vibration filtering, but still retains a bit of road feel for young drivers, which proves that it is an SUV that is fun to control.
