What are the differences between manual and automatic transmission cars?

The following are the differences between manual and automatic transmission cars: 1. Different levels of operational difficulty: Automatic transmissions mainly rely on the hydraulic transmission principle of the torque converter to complete gear shifts automatically. Manual transmissions primarily depend on the driver manually engaging the clutch to change gears, which is more cumbersome and requires the driver to have higher driving skills. 2. Different safety performance: Coasting in neutral with a manual transmission can lead to risks such as understeer or oversteer during turns. Additionally, if the engine stalls while idling, the car may lose power steering and braking, increasing safety hazards during driving. Automatic transmission cars cannot coast in neutral and maintain power support throughout the entire journey, making driving safer. 3. Different fuel consumption: When not using neutral, manual transmissions have slightly higher efficiency due to direct power transmission, resulting in slightly lower engine RPM at the same speed, which can save a very small amount of fuel. The main fuel-saving method for manual transmissions is coasting in neutral, where the engine only runs at idle speed. Automatic transmissions cannot coast in neutral, and the engine RPM in gear is significantly higher than idle speed, leading to differences in fuel consumption.
