Veteran drivers of fuel vehicles, whenever you see soaring oil prices, do you have a distressing feeling in your face? That's right, although the car is good, but the fuel cost can not be ignored, so "how to drive the most fuel-efficient" has become the number one topic in the hearts of many people. There is a saying that the most economical driving speed is between 70 and 80 kilometers per hour. Some people question, some people agree, this is very particular!
Imagine that when your car is traveling at less than 60 km/h, it's like a snail climbing a hill, and the engine has to work harder against drag and friction. You know, the engine is not very efficient at the moment, because it is burning a lot of fuel to fight these drags. On the other hand, when you step the throttle to speed above 90 km/h, wind resistance and rolling resistance are like invisible hands, and their strength does not increase by a little. This means that in order to maintain high speeds, the fuel consumption of the car will also increase.
However, some experts point out that the range of 85 to 90 km/h seems to be a sweet spot, which can meet the needs of efficient travel and relatively save fuel. Because in this speed range, wind resistance and rolling resistance are relatively low, and the engine is more efficient. However, please note that this is only the theoretical optimal condition, and real-life road conditions, weather, load and other factors will affect the actual fuel consumption performance.
In fact, in order to truly achieve fuel efficiency, in addition to pursuing that ideal speed, it is more important to cultivate good driving habits and concepts. For example, reasonably predict the road conditions and slow down in advance to reduce rapid acceleration and braking; Maintain your vehicle regularly, keep your tires at the right pressure, reduce unnecessary loads, and more. These are practical tips that can effectively reduce fuel consumption.
Having said that, we drive not only a car, but also a life. So, instead of getting too hung up on a specific speed, consider a variety of factors to make every trip both comfortable and energy-efficient. When driving, you must not only have a smooth ride, but also be careful in your budget!
