Fuel consumption of cars with automatic transmission is higher than that of cars with manual transmission.
Cause:
* An automatic transmission has a more complex design, which leads to greater energy losses due to friction.
* A manual transmission has more control over the engine, allowing the driver to select optimal gears to save fuel.
Approximate indicators:
According to the U.S. Environmental Protection Agency (EPA), cars with automatic transmissions consume on average 5-10% more fuel than cars with manual transmissions.
Factors influencing the difference in fuel consumption:
*Vehicle size
* Engine type
* Driving style
*Road conditions
Benefits of an automatic transmission in terms of fuel economy:
*Smoother gear shifting, which reduces energy loss.
* Torque converter lock-up feature that creates a direct connection between the engine and transmission at higher speeds.
Benefits of a manual transmission in terms of fuel economy:
* Less energy loss due to friction
* Greater engine control to select optimal gears
* Possibility of using impulsive run-out technique
Overall, if your main goal is fuel economy, a car with a manual transmission will be a better choice than a car with an automatic transmission. However, for many drivers, the convenience and ease of use of an automatic transmission outweighs the minor difference in fuel consumption.
