Why is the vision the same as the Emgrand engine, with similar weight and one liter less fuel consumption?

I happen to be the owner of Geely Emgrand. There are indeed many people who say that Geely Vision has low fuel consumption. In fact, SUV fuel consumption is relatively low. Although the weight of the two is similar, Geely Emgrand is bigger and slightly heavier, which has a great influence on fuel consumption in actual driving. There are many factors that affect vehicle fuel consumption, which are described in detail below.

Except for weight, engine and gearbox, the shape, tire size, width and pattern of the car have many influences on the fuel consumption of the vehicle. And in the long run, this car is lighter by more than 70 kilograms, which is equivalent to the weight of an adult. Over the years, there have been many influences. After all, as we all know, the fuel consumption of light vehicles and whole vehicles is very different.

Compared with the latest Geely Emgrand and Vision car, we can see that the tire size and width are the same, and the tire factor can be excluded. However, it should be noted that there is a big fuel consumption gap when the tire pressure is sufficient and the tire pressure is slightly insufficient. If the tire pressure is sufficient, the fuel consumption will be lower, because the friction resistance between the tire and the road surface will be smaller.

By comparison, it is found that Geely Emgrand is bigger, wider and longer than the prospective car, so it is different in aerodynamic layout and wind resistance, and actually more fuel-efficient than cars and SUVs. Small cars are more fuel efficient than big cars, and besides being lighter, the most important thing is that the wind resistance is relatively small.

Of course, apart from the difference in fuel consumption caused by the hardware of these cars, the fuel consumption of vehicles is related to the driving environment. For example, at high speed, it is definitely more fuel efficient than urban areas, and personal driving habits also have a lot to do with it, which is why it is also a Geely Emgrand car. Some people consume as much fuel as 9, while others only consume more than 6 and less than 7.

When I run in the city, I often encounter traffic jams. The average fuel consumption of my 18 Geely Emgrand automatic transmission is about 8.4, with little difference. There will be less in spring and autumn. If I run at a high speed, I will be fully loaded with about 6.9 oil. I don't know what level it is.
