For a long time, extended-range models have always been linked to high fuel consumption, and there are even such remarks on the Internet, 100 kilometers of ten oil new energy? To ridicule the extended-range models.
Although many people have painstakingly explained, it is because the first model of Li Auto, the Ideal ONE, uses a terrible, extremely low thermal efficiency range extender, which seriously lowers many people's first impression of the range extender model. As a result, the extended-range model was ridiculed on the Internet, and there are still many people who boycott the extended-range model for this reason.
But in the last two years, the fuel consumption of the extended range has been reduced, look at the following declaration diagram can be seen, the extended range models are different according to the size and level, the fuel consumption is also different, but compared with the same level of fuel vehicles, the extended range comprehensive road conditions are more fuel-efficient There is no doubt that the gap in urban fuel consumption will be greater, even if it is compared with the plug-in hybrid models of the same level, the gap between the two sides is not large.
However, many people subconsciously still feel that the fuel consumption of the extended range is a little higher than that of plug-in hybrid models, the main problem is not because of the technical route, but because the new forces that make the range extender are the majority, at present, although Geely, BYD, Chery, Changan, BAIC, Dongfeng and other car companies have launched extended range models, but most of them are launched as new power brands under traditional car companies, and only Changan and Chery are truly aware of the huge market for extended range models. As soon as the traditional car giants make a move, the true value of the range extender is reflected.
For example, the Star Era ET car, the extended range version of the engine thermal efficiency of 44.5%, WLTC feed fuel consumption of 5.2L/100km, full fuel and full battery range of more than 1500 km, its length 4955mm, width 1975mm, height 1698mm, wheelbase of 3000mm, curb weight is 2.14 tons.
Compared with the plug-in hybrid models of the same level, the Wei brand Lanshan is a lap larger than it, with a curb weight of 2.39 tons, WLTC feed fuel consumption of 6.2 liters, Lynk & Co 09 curb weight of 2.47 tons, and WLTC feed fuel consumption of 7.5 liters.
Compared with the 6.9 liters of the ideal L6, the 7.4 liters of the ideal L7, the 7.5 liters of the ideal L8, and the 6.85 liters of the M7, the fuel consumption of the Star Era ET is also a lot lower. Don't say that the fuel consumption data of the Ministry of Industry and Information Technology is inaccurate, this is measured under the control variable, which is more referential than your friends, your colleagues, your neighbors, and Uncle Zhang in the village next door.
Similarly, let's take a look at another traditional manufacturer, Changan Automobile. Changan Qiyuan A07 feed fuel consumption is 5 liters, Changan dark blue S7, feed fuel consumption is 4.95 liters, you compare the same level of models, whether it is a range extender or plug-in hybrid, what is the result?
To put it bluntly, the same technology, it also depends on who uses it, the new forces of car manufacturing, most of the engines are purchased, there is no ability to develop their own internal combustion engines, even if it is the so-called self-development, they have only been building cars for a few years, how strong is the accumulation of technology? How strong can it be a range extender for its use? However, the traditional manufacturers are different, the range extenders they use, without looking at other data, the thermal efficiency alone is obviously a big cut away from their opponents. The same is true for fuel consumption data, in the case of a good range extender, the difference between the fuel consumption of the range extender and the plug-in hybrid model is really small, and may even be better than the plug-in hybrid model.
The reason, we have said many times, the extended range model can always be maintained in the high efficiency range of power generation, whether it is urban or high-speed, as long as the high thermal efficiency range is wide enough, and the plug-in hybrid model is different, the engine should consider direct drive, but also consider parallel, even if it is running at high speed, it may not be guaranteed to run in the high-efficiency range, because running at high speed will encounter turtle speed cars, need to slow down and speed up frequently, and cannot cruise in a steady state, which will lead to fluctuations in thermal efficiency.
In fact, for traditional manufacturers, let go of the so-called pride and identity, to lay out the extended-range models, it is absolutely wise, in the era of electric drive, and then to engage in internal combustion engines and gearboxes This set is not promising, the ideal sees clearly, BYD understands, Huawei understands, Chery also understands, only a few car companies are still obsessed.
