The so-called coasting in gear and coasting in neutral gear of manual transmission cars are indispensable driving conditions for the driver, and both are indispensable. So when driving on the road, whether it is the correct coasting in neutral gear or the correct coasting in gear has also been bothering many drivers. In fact, it is very simple, these two skills are essential skills that drivers should have, there is no right or wrong, but the term "coasting with gear" is really a misnomer, which confuses many people's audio-visual and audio-visual.
Actually, the term "gear gliding" is not appropriate. Because any moment when the driver releases the clutch and relies on inertia after shifting, it will belong to the engine braking, which is not really coasting. The real gliding should be in neutral mode, the kind of driving that is unrestrained and does not have any sense of drag, can be called gliding.
Coasting in neutral can significantly reduce fuel consumption, because in neutral, the driving force of the engine cannot be transmitted to the drive wheels, and it relies entirely on the car's own inertia to travel a certain distance. In this state, not only is the fuel consumption extremely low, the coasting distance is longer, and the driver can fully experience the convenience and fun of coasting. The meaning of coasting is not only fuel saving, but also a kind of psychological freedom for the driver, in addition, the engine can not be turned off in order to be more fuel-efficient, once the engine is turned off, it may lead to brake immobility and steering failure. This is an extremely dangerous operation in some special road conditions.
The so-called "coasting with gear" is actually engine braking. No matter what kind of car, when we hang up the top gear, the gear speed ratio is generally extremely close to the one-to-one gear ratio, although the braking effect of the engine is not obvious at this time, but it still has a certain braking effect. And the lower the gear, the more significant the braking effect. Therefore, even the highest gear belongs to the category of engine braking, and there is no such thing as "coasting with gear". Gears do not coast and can greatly limit the driving distance.
Engine braking also has its place, if you lose this function then it is not good, completely lost, it will be a very terrible thing, because in some special road conditions, the loss of engine braking, will make the stability of the car decline, just rely on braking is far from enough. For example, in the environment of long slopes, steep slopes or rain and snow, relying only on the braking force is very easy to lead to the thermal attenuation of brake components, especially for large and heavy vehicles.
All in all, there is a clear difference between neutral coasting and engine braking in some scenarios, but they are indispensable. Coasting in neutral significantly reduces fuel consumption and allows for longer coasting distances, while engine braking gives the driver greater control over the stability of the vehicle. Therefore, in actual operation, we should choose the most suitable driving mode according to the actual situation to get the best driving experience and driving safety, rather than characterizing a driving mode as black and white.
