In the past 70 years since the birth of the domestic automobile industry, China's automobile industry has always been struggling. As early as 1885, Carl Benz invented the first modern car, and it was not until 1958 that our first domestic car came out, when it was really difficult to build our own domestic car. After the reform and opening up, we hoped to use the "market for technology" and steal a little technology in the joint venture, but foreign car companies stubbornly covered the core technology, only Brands such as Mitsubishi and Toyota, because of the environment and special reasons at that time, sent us some backward technology.
Since entering the new century, in order to obtain market sales and compete with powerful joint venture cars, domestic cars have tried their best to "hit small cars with big cars", "low prices to hit high prices", "high matching to play low", "intelligent to fight non-intelligent" and so on. Fortunately, geely Great Wall Chery Changan these brands have not given up, and domestic cars have finally ushered in the opportunity to counterattack, that is, hybrid models.
In 2021, the domestic hybrid system is blooming, BYD's DM-i, Great Wall's lemon DHT, Changan's IDD, Chery's Kunpeng DHT hybrid, Lei Shen Zhiqing Hi · X, these five major hybrid technologies, is the beginning of the "roll-to-die" joint venture car, but also the beginning of the rise of domestic production.
Many people think that I am alarmist, so let's talk about this matter, the reason why the domestic hybrid system is so important is because it solves several problems.
Technically
In the era of fuel vehicles, the reason why domestic cars should compete with joint venture vehicles in terms of configuration, size and interior design. It is because the core technology of the three major parts is not as good as the joint venture car, and in terms of engine, although the domestic engine looks very high in thermal efficiency, it really depends on the highest thermal efficiency range, or it is far behind. To say performance, foreign brands of various high-power versions of the engine, and then to the domestic car 20 years may not be able to catch up. The gearbox gap is even greater, not only on the product, but also in the power matching. But the advent of hybrid systems solves several problems:
1, domestic cars no longer need to develop a comprehensive engine, hybrid engine in the low-speed power generation, high-speed direct drive, low-speed rise power, NVH control, fuel economy, are no longer a problem, the technical difficulty is greatly reduced.
2, hybrid special engine, the use of Atkinson cycle plus ultra-high compression ratio, you can have super high thermal efficiency, what thin combustion, variable compression ratio, variable cylinder, continuous variable timing and other technologies, all bypassed. And most of the time is in the highest thermal efficiency range of operation, domestic vehicle fuel consumption of high stubborn disease has been overcome.
3, no longer need the intercooler, EGR waste cycle, the engine structure is simplified, maintenance is cheaper, the stability is better, coupled with the engine is basically in the high efficiency range, the carbon deposit problem is greatly reduced.
4, the most card neck of the gearbox problem is no longer a problem, no matter what CVT, AT, DCT, are replaced by variable gears, durability beyond AT, smoothness beyond CVT, power responsiveness beyond DCT, perfect.
5, the previous domestic basically no decent performance car, Lynk & Co 03 + may be counted as one, but compared with the performance of foreign brands, the gap is too big, EA888 brush an ECU, you can easily get on 300 horses, and now, as long as you change to a higher power motor, easily achieve faster zero hundred acceleration.
Therefore, technically speaking, the hybrid model solves the problems of the previous domestic car, high fuel consumption, weak power performance, weak transmission technology accumulation, poor power matching, etc., so that domestic cars can easily get the opportunity to catch up with or even surpass the joint venture car.
Product-wise
A lot of people say, aren't these electric cars you said do it too? Why do you have to tout hybrid models so much? That's because at this stage of pure electric models, there is still no possibility of large-scale popularization.
As early as last October, China officially released the "Energy-saving and New Energy Vehicle Technology Roadmap 2.0", which proposed in the overall goal that by 2035, energy-saving vehicles and new energy vehicles will account for 50% of sales within 15 years to 2035, and energy-saving vehicles refer to HEV hybrid models.
Compared with pure electric models, hybrid models are less dependent on infrastructure, less affected by speed and temperature, and can cover more car scenes, while bydir and Great Wall pure electric vehicles with a range of more than 200 kilometers have come out, which also means that hybrid models cannot take into account the ultra-low cost of use and excellent driving experience of pure electric models. In the next 5 or even 10 years, in the absence of breakthroughs in battery technology, hybrid models may be a better choice than pure electric models.
In contrast, at present, the hybrid system of foreign car brands, European and American car companies generally use a relatively backward P2 architecture, and they are unable to compete with domestic dual-motor series parallel hybrid models in terms of power loss and fuel consumption. The Japanese car companies, Toyota's hybrid, Honda's dual motor series parallel, Nissan's tandem, although the fuel economy and domestic hybrid are close, but counting the brand premium, in the price is unable to compete with domestic cars. This is the opportunity for domestic hybrid models, and it is also the real reason why independent brands with some ambition have to launch their own hybrid systems.
In addition to BYD's DM-i hybrid, we also hope that more independent car brands will launch more competitive products, and work together to grab back the market share of joint venture cars, the domestic automobile industry has come all the way to the past 70 years, too difficult and too difficult, fortunately we have persevered, and now, belonging to the best era of domestic cars, has come!
