Common misconception: "An automatic transmission consumes more than a manual transmission."

For a long time, only a manual transmission was used in cars. Today the automatic transmission has gained market share, although the manual transmission is still more used in Europe than in America. An automatic transmission offers more comfort but has a reputation for being more fuel efficient than a manual transmission.

True or False: "The consumption of the automatic transmission is greater than that of the manual transmission"?

TRUE, but ...

La Transmission allows you to transfer the rotational energy of the engine to the axle and wheels, which reaches it through flywheel иclutch... There are different types including automatic transmission and manual transmission. The latter works through the clutch, and the automatic transmission itself shifts without any action from the driver.

Typically, the operation of an automatic transmission should result in the gears being engaged at the most appropriate time. In theory, this should result in more optimal and therefore lower fuel consumption.

However, a manual transmission allowsbetter adapt your driving and in particular practiceeco driving... As the driver controls the transmission, he can anticipate, avoid unnecessary stops, drive as smoothly as possible, and resume at the desired speed.

Since it is automatic and therefore a stand-alone system, an automatic transmission does not have this capability. Thus, by adapting your driving, you can consume from 5 to 15% less fuel with a manual transmission compared to an automatic transmission.

However, this does not apply to all drivers and all types of driving. In fact, motorists who drive sporty or shift gears late cannot claim such a reduction in fuel consumption with a manual transmission. There the automatic transmission takes revenge!

In addition, there have been changes in gearboxes in recent years. Today's overrun of an automatic transmission very limited, or even zero on very fresh cars. They are really designed to consume as little as possible. It even happens that some models in automatic transmission consume less than in manual transmission.

Thus, the consumption of an automatic transmission has changed, especially because it also depends on the type of technology considered - because there are several of them! Single box or double clutch, CVT gearbox or torque converter gearbox ... each has its own consumption. On boîtes In the past generation, the advantage of the manual transmission has been eradicated.
