Does driving slowly save fuel?
Many drivers believe that driving slowly can help save fuel, but is this true?
According to many experts in the auto industry, this is a subjective, emotional and baseless thought.
Because, in fact, there is no general rule that applies to all types of cars, related to speed to optimize fuel economy. Each car model will have its own technical parameters and are completely different. Therefore, the speed to optimize fuel consumption is also different.
In addition, when driving too slowly, the engine will usually rotate at a low speed, ranging from 1,000 - 3,000 rpm. At this time, the car will run in a low gear, the engine rotation speed per km will be greater. This causes the engine to burn more fuel to respond to each rotation cycle.
However, if you are travelling at high speeds, the advantage is that the car will shift into a higher gear, but still maintain the engine rotation between 1,000 - 3,000 rpm. In theory, this will help consume less fuel. However, the higher the speed, another problem will appear, affecting the fuel consumption index. That is air resistance.
When the car moves fast, the air resistance will also increase significantly. At this time, the engine will have to work harder to overcome the resistance. Therefore, the fuel consumption will also increase and depending on the car model and design, with different aerodynamic indexes.
Because it depends on many factors, it is difficult to confirm whether driving fast or slow will help save fuel. This also means that driving slowly will not necessarily help drivers save fuel.
Besides the model and type of car, driving properly and skillfully will also help drivers save a considerable amount of money. Therefore, instead of trying to drive slowly, there are still many other "secrets" to optimize fuel consumption.
First is to calculate and choose a convenient route when traveling. Especially in big cities like Hanoi and Ho Chi Minh City, traffic jams often occur. If traveling by car, drivers should choose the shortest route with less congestion. This will help the car consume less fuel.
In addition, drivers should consider and remove unnecessary goods and items from the car. The reason is that often leaving many unnecessary items and goods in the car will make the car heavier, when moving... the car needs more energy from the engine to operate, leading to more fuel consumption.
When driving in the inner city, pay attention to observe if there is a traffic light or a lot of traffic ahead. Drivers should estimate the distance to keep the vehicle at a steady speed, avoiding losing momentum, stopping, and having to step on the gas to regain momentum.
