How to reduce fuel consumption when shifting gears?

There is an opinion that a manual transmission is suitable for a frisky ride, and an “automatic” is suitable for leisurely trips around the city. At the same time, the "mechanics" makes it possible to save gasoline in the event of a correct gear change. But how to do it correctly, so as not to reduce performance? The general principle is this - you need to squeeze the clutch, change the stage, and smoothly release the clutch pedal. But not everything is so simple.

When to change gear

Experienced drivers know that there are average speeds at which it is best to upshift or downshift. The first gear is suitable for driving at speeds up to 20 km / h, the second - from 20 to 40 km / h, 40-60 km/h — third, 60-80 km/h — fourth, then fifth gear. This algorithm is suitable for smooth acceleration, when you drive for a long time at a speed, for example, 50-60 km/h, then you can turn on the "fourth" earlier.

However, greater efficiency can be achieved by changing the stage in the correct engine speed range. So, on passenger gasoline subcompacts, it is better to shift gears when 2000-2500 rpm. For diesel versions of the engine, this figure is several hundred revolutions less. For detailed information on engine output (maximum torque), please refer to the owner's manual.

How to change gear?

For maximum efficiency of gear shifting and fuel economy, there is a certain algorithm of actions:

1. We squeeze the clutch with a sharp movement “to the floor”, at the same time we release the accelerator pedal.
2. We quickly turn on the gear we need, smoothly moving the gearshift lever to the neutral position, and immediately after that - to the position of the gear we need.
3. Then gently release the clutch and gently increase the engine speed to compensate for the loss of speed.
4. Release the clutch completely and add gas.

Of course, in the event of a sharp deceleration or for acceleration on the descent, the gears can be switched out of order, for example, from fifth to third, from second to fourth. But with a sharp set of speed, you can not skip steps. In addition, in such cases, it is recommended to "unwind" the engine speed and shift gears at higher speeds.

Inexperienced motorists can make mistakes that increase fuel consumption and accelerate the wear of some assemblies, mainly the clutch. Beginners sometimes abruptly throw the clutch, because of which the car starts to twitch. Or vice versa - the switching is too scattered, and then the engine speed drops. In addition, a typical rookie mistake is switching late and over-revving, which causes excessive fuel consumption and unnecessary noise in the engine.

One neat trick that can be done with the help of a gear change can help here - engine braking. Such braking is especially effective when descending steep slopes, when the brakes fail or when driving on an ice-crusted track. To do this, release the gas pedal, squeeze the clutch, downshift, and then release the clutch. When braking with the engine, it is very important to feel the car and not over-rev, which will naturally increase if you downshift and maintain the current speed. The greatest effect can be achieved if both the engine and the pedal are braked at the same time.

Achieving proper gear shifting is not at all difficult. It takes some getting used to. If you use the "mechanics" daily, then the skill will come quickly enough. Not only will you be able to enjoy manual transmission, but also competently reduce fuel consumption.
