concern
In the past two years, the new forces of independent car companies have launched many Internet celebrity models that can be called "god operation", such as the ideal ONE, the M5, and the newly listed Lantu Dreamer, which is a full range extender hybrid car. If there is still a dispute between the P2 hybrid of the European and American systems and the dual motor hybrid of the Chinese/Japanese system, who is the future of the hybrid, then the extended range hybrid is undoubtedly "turning the technology backwards".
Consumers may wonder, a new car company with no technical reserves, why do the cars made are two or three hundred thousand, or even more than four hundred thousand? However, the Great Wall, Chery, and BYD, which have certain technical strength and research and development capabilities, can only survive under the "encirclement and suppression" of joint venture vehicles.
Taking the originator of this type - the ideal ONE as an example, when the manufacturers do product promotion for this car, they emphasize its digital level, what intelligent car machine, driving assistance, high-end configuration, but the powertrain, chassis architecture is closed. For users, its inertial thinking is that this car can indeed meet its own demands, but oil and electricity, on the green card, and good 300,000 cars, the three major pieces will not be too bad, not to mention compared with "BBA", at least stronger than Volkswagen / Toyota.
In fact, as a new force in car manufacturing, ideal car is completely zero-based in the development of engines, transmissions, and chassis, and none of these three major parts are self-directed and positive research and development.
For example, the ideal ONE, which is selling very well, is very popular:
First, the 1.2T in-line three-cylinder engine is actually provided by Dongan Power, the model is DAM12TD, the technology is backward, the thermal efficiency is low, not to mention the economy compared with the Toyota/Honda hybrid special engine, than the NVH, even the independent brand of the Great Wall, Geely, Chery, BYD also look down on this small displacement three-cylinder machine;
Second, the extender hybrid system does not require a gear transmission, and the electric drive itself has its own speed regulation function, which is a big surprise for any new car-making force, neither development nor procurement;
Finally, the chassis, the ideal ONE is the reverse of the chassis architecture of the previous generation Toyota Highlander, no resources, the basic operation of start-up car companies.
I have to say that the original, the ideal ONE is afraid that only the body in white is developed by itself, and it is also difficult for TA.
Then there is the integration of the powertrain, including the ideal ONE, and the green-brand hybrid vehicles of the new domestic car-making forces have chosen the range-extended hybrid scheme with the lowest technical threshold. Because there is a large capacity battery pack, so the daily car is completely driven by pure electric cars, when the battery is out of power, the engine will drive a generator to drive the motor & battery power, providing emergency endurance. But anyone who has received nine years of compulsory education can understand how this thing works, and does not require a complex mechanical structure and electronic control system.
Range extenders can be added
Why is it said that it is a technical reversal? I don't know if you have learned about the pure electric tricycle market in the third-tier cities & urban and rural areas, the 50-year-old uncles bought back a large-scale modified range extender, that is, add a mini gasoline generator, the price is about 3,000 yuan, so that the car is not afraid of running out of electricity, in essence, it is actually the same thing as the ideal ONE and Lantu dreamer of three or four hundred thousand.
There are more outrageous foreign countries, YouTube has car owners after buying Tesla's pure electric car, directly buy a gasoline generator in the trunk, or Honda's, the car is out of power after the charge will be charged for a while. There are always more ways than difficulties, and it is simply not too clever.

Ask the M7
So the question is, why are the first-line car companies now eliminating this simple and effective range extender hybrid technology? In fact, the core factor or this technical solution is defective, gasoline generator can only be used as a backup emergency endurance, once the range extender starts, not only the NVH performance will decline, and the electricity generated is far from enough for the two motors to squander, which will seriously affect the user's value experience. To put it bluntly, it is a Tibetan mastiff when there is electricity, and it becomes a teddy when there is no electricity.
In order to solve the defects in this regard, the current more popular dual-motor hybrid, such as BYD DM-i, Great Wall Lemon DHT, Chery Kunpeng DHT, not only has a powerful electric drive system, the engine is not only used as a range extender, can also directly drive the vehicle, the battery is powered or not, and will not affect the power performance of the vehicle, the noise level is also maintained at a relatively acceptable level.
Of course, the ideal car has cut a lot of leeks over the years, and now there is a certain amount of capital to do the research and development of three major pieces and three motor systems. For example, the latest full-size SUV , the Ideal L9, which is equipped with a 1.5T engine not only increases the displacement, but also changes to an inline four-cylinder system, although it is still customized from Dongan Power, but at least there are new technologies such as Miller cycle and high-pressure direct injection, which can also be regarded as on the table.
However, as a backward hybrid technology, extended range hybridization must not be the future of passenger cars, and as consumers' understanding of hybridization gradually deepens, there is not much time left for ideal cars, Lantu cars, and Huawei Celis.
