Is automatic gear more fuel efficient than manual gear?

1, because there are many factors that affect fuel consumption, such as congested road sections, expressways and urban road conditions. In all cases, the fuel consumption varies greatly. When driving in urban areas, manual gears frequently start and shift gears, but the fuel consumption is higher than that of automatic gears. The fuel consumption of automatic transmission and manual transmission is almost the same under different working conditions.

2. Sometimes automatic transmission is more fuel efficient, and driving technology is the main reason that affects fuel consumption. Novices have poor driving skills, slow start, and delayed gear shifting. Driving a manual transmission consumes more fuel than an automatic transmission. Old drivers can accurately grasp gear shifting, give full play to the effect of manual transmission, and save fuel than automatic transmission. But now the automatic gear is close to the manual gear, even if the old driver drives, the fuel consumption is similar.

3. The reason why automatic transmission is more fuel-efficient than manual transmission is because there is a hydraulic coupling in automatic transmission under the same conditions, which will lose some energy during operation, which is also the main reason why automatic transmission is more fuel-efficient than manual transmission.

Extended data:

Under the same conditions, the oil consumption of automatic transmission is higher than that of manual transmission because there is a hydraulic coupling in the transmission of automatic transmission, which will lose some energy during operation, which is also the main reason for the higher oil consumption of automatic transmission than manual transmission.

And the automatic gearbox is provided with an oil pressure system for providing power oil for the hydraulic gearbox. This kind of power oil system generally needs about 5 kilowatts of power transmission, and in addition, it will lose some energy because of the role of torque converter when driving. However, this device requires the vehicle to enter a gear as far as possible when driving, so that the oil pump can run continuously, otherwise the automatic gearbox running in N gear will be burned because of insufficient oil pressure.
