In the past, independent brands have been lagging behind overseas car companies at the core technology level, which is understandable, after all, the start time is late, and the production system and industrial chain scale are lagging behind others. However, from the situation in recent years, this passive situation is gradually improving, and independent brands are no longer a blank in terms of core power technology. For example, in the past 2021, there are many power systems on the market that do not lose joint ventures.
BYD DM-i
At the beginning of the year, BYD released Qin PLUS DM-i, Song PLUS DM-i, Tang DM-i three blockbuster models, of course, the car is not the focus, the key is that this hybrid system can do the same as Honda or even lower level in terms of energy consumption, the official claim that in the state of battery power loss can also reach 4.4L of 100 km fuel consumption, you know, whether it is THS or i-MMD, their fuel consumption is also about 100 kilometers 5L.
This hybrid system is composed of a special engine for Snap Cloud plug-in hybrid, an EHS electric hybrid system, a blade battery, and a drive motor. In the vast majority of the time, the vehicle is driven by an electric motor, which brings the ultimate smooth driving sensation, and at high speeds, the engine will intervene in operation to reduce unnecessary power loss.
After the release of the DM-i model, the market set off a rush to buy, orders piled up, and even consumers because of the delay in mentioning the car and ran to the website to complain, it is thanks to this, BYD last year's new energy passenger car sales reached 593,000, an increase of more than 200%.
Great Wall 3.0T+9AT
When many car companies are announcing the cessation of internal combustion engine research and development and the full turn to electric drive, the Great Wall is still sticking to this field. For example, the powertrain of the 3.0T+9AT used in the new tank tank 500 is not only a symbol of great wall motor's strength, but also an important milestone in the history of its own brand.
This 3.0T machine uses a number of mainstream technologies, including hybrid injection, 350Bar in-cylinder direct injection, integrated water cooling, dual VGT superchargers and more. The maximum power is 260kW, the peak torque is 500Nm, and the power parameters are not worse than the current mainstream BBA's 3.0T power. In addition, this gearbox is also the only longitudinal 9AT at present, so the Great Wall's set of power is worth looking forward to.
NO.3: Great Wall DHT hybrid
In addition to BYD's DM-i in the hybrid market, the GREAT Wall DHT hybrid is also a very important set of powertrains this year. Lemon DHT hybrid platform is divided into HEV hybrid and PHEV hybrid, this system belongs to the hybrid architecture, the working principle and Honda's i-MMD is very close, but its innovative addition of two-speed transmission, so that it can have the ability to change speed, in the low and medium speed driving can also provide good acceleration performance, can achieve series, parallel and pure electric multiple operating forms. In terms of structural composition, it is equipped with a special engine, a high-energy density power battery, a driving motor, and a two-speed transmission.
At present, this hybrid system is mainly used in the models of the WEY brand under the Great Wall, including Macchiato and latte, mainly based on HEV oil-electric hybrid, which is the biggest difference between it and BYD DM-i.
NO.4: Trumpchi Julang power
Thanks to the opportunity of cooperation with joint venture brands for many years, GAC Trumpchi has gradually established a systematic core technology construction platform, and Julang Power is the result of these years, of which the 2.0T engine is impressive. Currently mounted on the GS4 PLUS, GS8 is the third generation of products, the application of the current market mainstream technology, including high compression ratio, EGR exhaust gas recirculation, low friction and lightweight design, GCCS combustion control system, 350bar high-pressure direct injection, etc., the maximum horsepower of 252 horses, peak torque of 400Nm, compared to Audi's high-power EA888, BMW's B48 and other joint venture 2.0T engines are not behind.
NO.5: Chery Kunpeng 2.0T
Chery, as the earliest car company in China to develop core power, has accumulated quite deep technology in engine technology, and released a new 2.0T Kunpeng power in the first quarter of this year, which was first applied to its flagship SUV Xingtu Lanyue. In-cylinder direct injection and low inertia turbines can provide fast enough power response, and the all-aluminum cylinder block is more helpful for the lightweight of the whole vehicle. The maximum horsepower reaches 254 hp and the peak torque is 390 Nm. Up to now, this power has been applied to many models of Chery, including Tiggo 8 Kunpeng Edition, Xingtu Lingyun and so on.
I have to say that from the previous batch procurement, reverse development and imitation, and now from scratch to shoulder joint ventures, the progress of independent brands in recent years is gratifying.
