Which is More Fuel-Efficient: Automatic or Manual Transmission?

[AngelaRose]

Generally, manual transmission vehicles are slightly more fuel-efficient than automatic ones. Here are the relevant details: 1. For vehicles of the same brand, model, and engine displacement, manual transmissions typically offer slightly better fuel economy than automatics. However, this isn't an absolute rule as many factors affect fuel consumption, including road conditions, fuel quality, driving habits, and vehicle maintenance. 2. Most manual transmission cars use gearbox shifting, which provides high mechanical transmission efficiency with minimal delay, resulting in excellent power output efficiency. Automatic transmissions rely on transmission fluid and torque converters for power transfer, which leads to greater transmission power loss.
