Give him a 15T equation Leopard Leopard 5, he can give you 18L 100km fuel consumption at high speed, just ask if you can stand this Recently, a blogger posted on the Internet that it measured the high-speed fuel consumption of Leopard 5 is 18L 100km, which is far from the official propaganda of power loss fuel consumption. The Leopard 5 was actually just launched in November this year, and it is a plug-in hybrid mid-size SUV that focuses on the off-road SUV market and is priced at 28Starting from 980,000 yuan, curb weight 289t, fuel consumption is 78l/100km。
After a few days of heated discussions on the Internet, Formula Leopard Automobile responded to the matter and disclosed the problems existing in its driving. Formula Leopard officially issued a statement, and the data showed that the vehicle had a large number of abnormal driving behaviors on that day, including but not limited to the following points. 1. During the whole high-speed driving process, there are 3 time periods when the speed exceeds 180km h, and 6 time periods when the speed exceeds 170km h. 2. In the whole section of high-speed driving, the speed of 120 140km h accounts for more than 37%, the speed of 140 160km h accounts for more than 46%, and the speed of more than 160km h accounts for more than 4%. 3. Abnormal parking time was found in some sections of the expressway.
Immediately, a professional ** also measured the equation Leopard 5 in the winter test of extended range plug-in hybrid electric fuel consumption test, and the fuel consumption performance was 741L 100km, if it is put in spring and summer, maybe the fuel consumption will be lower. To give a few examples, the tank 300 2The official fuel consumption of the 0t power version is 99L 100km, the fuel consumption that most people can run out of daily cars is about 12L 100km. Corolla 1The fuel consumption of the 2T power version is about 7L 100km per 100km, and the actual high-speed fuel consumption is 5Up and down 8L, these data can basically be confirmed by actual measurements in the vast majority of car environments.
According to the common sense of using the car, generally on the basis of the official comprehensive fuel consumption plus 2 3L, often can get the real fuel consumption level of the vast majority of people's daily cars. Even if the testers conduct extreme tests on the vehicle, the fuel consumption per 100 kilometers can be understood as high as 11 13L, but this time the comprehensive fuel consumption of 100 kilometers at high speed runs 18L, which is indeed a bit unexpected. In everyone's perception, running at high speed must consume less fuel than driving in urban areas. However, in fact, the speed of 120kmh or more is not the most fuel-efficient, and there are actually two important factors that determine the fuel-saving speed on the highway: the size of the car's displacement and the drag coefficient.
In general, domestic models with small displacement, 1For self-priming models of 6L and below, the most fuel-efficient driving environment is in the range of 70 90km h, the engine has reached the best working condition, the fuel combustion is sufficient, and the fuel consumption and power have reached a balance point. If it exceeds 100km h, especially above 120km h, fuel consumption increases significantly. In fact, in high-speed driving, the most important point to increase fuel consumption is the drag coefficient, which is why major automobile manufacturers will focus on the design of the body when building cars.
If the car wants to reach high speeds, it must generate more traction. There is a formula that can be calculated: f=1 2cpsv, where c is the drag coefficient, p is the air density, s is the wind area, and v is the velocity. If the drag coefficient, air density, and frontal area of the car are constant, then the wind resistance is equal to the square of the velocity, which means that when the speed is doubled, the drag will reach four times. The original driving speed is 60 km/h. When reaching 120km h, the drag increases fourfold. Most of the engine's power has to overcome this resistance, so today's pure electric vehicles, especially cars, are pursuing the lowest possible drag coefficient.
Summary: Back to the incident itself, according to the information of the current case, it is speculated that if the blogger measured such fuel consumption through high-speed, speeding, and emergency braking in the state of the vehicle's power loss, it would be quite unrigorous. Because, all plug-in hybrid off-road models drive under such conditions, fuel consumption will not be too optimistic. After the above analysis, such a hard off-road vehicle in high-speed driving, the biggest impact on fuel consumption is the confrontation with wind resistance, so we still have to drive in accordance with the speed within the limits of safety regulations, one is to control fuel consumption, and the other is the biggest responsibility for their own safety.
