How does a manual transmission generally compare to an automatic in terms of fuel efficiency?

A manual transmission generally provides better fuel efficiency than an automatic transmission due to its design and operation. In a manual transmission, the driver has direct control over the gear selection, allowing for optimal engine performance and RPM management. This control often leads to more efficient use of fuel, especially in steady-state driving conditions where the driver can select the most appropriate gear for the situation.

Manual transmissions typically have a simpler mechanical design and do not include the extra components found in automatics, such as torque converters, which can lead to energy losses. As a result, manual transmissions can transfer power from the engine to the wheels more efficiently, contributing to improved fuel economy.

While modern automatic transmissions have advanced significantly and can sometimes match or even outdo manuals in fuel efficiency due to technologies like CVTs (Continuously Variable Transmissions) and dual-clutch systems, traditionally, manuals have been regarded as the more fuel-efficient option. Therefore, the answer indicating that manuals can offer better fuel efficiency aligns with the principles of how manual transmissions operate compared to automatics.
