In the car evaluation circle on the Internet, there seems to be such a contempt chain, plug-in hybrid does not look at the range extender, multi-gear plug-in hybrid does not look like a single-gear plug-in hybrid, range extender and plug-in hybrid do not look at the gasoline-electric hybrid, and the hybrid system does not look down on pure fuel vehicles.
Let's not talk about the rest for the time being, let's just say that this multi-gear DHT plug-in hybrid, is it really stronger than a single-gear plug-in hybrid? Now car critics don't talk about the Basic Law? Looking at the parameters, looking at the promotional draft of the car company, where is the Ka Ka blowing?
In recent years, domestic car companies have set off an "arms race", BYD has launched a single-gear plug-in hybrid route, Great Wall, Geely, Chery and other car companies have successively offered 2-gear, 3-gear DHT scheme, not only the structural principle is more complex than the other, but also many consumers who want to buy hybrid cars have successfully wound into the cognitive whirlpool:
Is multi-grade DHT plug-in hybrid really more advanced than single-gear plug-in hybrid? The more gears, the more advanced the technology? The more worth buying?
Many people are diode thinking, multi-gear DHT gears more, more modes, that is, better, but automotive products are the art of compromise, any technology to gain benefits at the same time, will pay the price, since multi-gear DHT is better, why don't car companies launch 6-speed DHT, 8-gear DHT?
Let me ask you a question first, which is the best multi-grade DHT plug-in hybrid model currently sold on the market? The answer is the Galaxy L7. In March, more than 3,000 units were sold.
Some people say, you are talking nonsense, it is obviously Lynk & Co 08 EM-P, more than 5,000 units have been sold, but you must know that although Lynk & Co 08EM-P is a 3-speed DHT structure, it is officially called EM-P super electric range extension program, because 08 EM-P is in the same state of feeding as the extended range electric vehicle, the P1 motor located at the end of the engine crankshaft starts to generate electricity driven by the engine, and the P3 motor is driven, and the driving principle at this time is the same as that of the extended range power model. It is different from the multi-level DHT of other car companies.
The best-selling single-gear plug-in hybrid model sold 30,000 units in March, and in addition, there are many models that sell more than 20,000 and sell more than 10,000 units. So, why is the sales volume of the more technologically advanced multi-grade DHT plug-in hybrid said on the Internet blown up by the single-grade plug-in hybrid?
Cost is a critical factor
Last year, the price of multi-gear plug-in hybrid and single-gear plug-in hybrid can still be played back and forth, but this year, you see, BYD Qin PLUS and Changan Qiyuan A05 hit the price of single-gear plug-in hybrid models to 79,800 yuan, and other car companies were dumbfounded, how can this follow?
As I have said a long time ago, single-gear plug-in hybrid and multi-gear plug-in hybrid are completely unable to compete in cost, and the cost is reflected in the price.
Ride is also an advantage of single-gear plug-in hybrid
The reason why the multi-gear plug-in hybrid is added to the gearbox, one is to bypass Toyota, BYD's technical patents, and the other is to better play the strength of the engine, the multi-gear plug-in hybrid in the case of thirty or forty per hour, the engine can intervene, which can make up for the possible shortcomings of the motor drive, but this will lead to the generation of frustration problems, compared with the range extender and single-gear plug-in hybrid, the smoothness of the multi-gear DHT must be worse, but the degree is different.
In terms of failure rate, single-gear plug-in mixing has an advantage in theory
Why theoretically? Because the manufacturing level of various car companies is different, the quality control is different, but theoretically speaking, the failure rate of single-gear plug-in hybrid and extended range models must be a little lower.
In fact, the biggest reason why multi-gear DHT plug-in hybrid is not popular is the cost, which leads to the fact that in terms of selling price, multi-gear DHT plug-in hybrid models are often high, and if you add a large battery, the cost will be out of control, which greatly affects the sales of such models. In addition, BYD's plug-in hybrid is preconceived, which leads to the plug-in hybrid of other car companies, and it is difficult to establish product awareness, which is also a reason. In the final analysis, the technology still has to return to the product, you have 2 gears 9 molds, I 3 gears 21 molds, for consumers have no meaning, but only increase the manufacturing cost and tuning difficulty, so the development route of multi-gear DHT plug-in hybrid, may need to change, like Chery Chang'an, switching to the range extender, may be a more reasonable choice.
