What is the most fuel-efficient speed for a 4AT transmission?
1 Answers
Fuel efficiency is not significantly related to speed or the type and structure of the transmission. The key to saving fuel lies in controlling the engine's RPM. Here are the details: 1. On highways: If driving on a highway, maintaining a constant speed, such as around 110 km/h, and avoiding braking and sudden acceleration can help save fuel, as these actions may cause RPM fluctuations. 2. Engine RPM: For a 4AT transmission, these fluctuations become very noticeable. To achieve better fuel efficiency with a 4AT, the secret is to keep the engine RPM as stable as possible. The engine's RPM is the most critical factor affecting fuel consumption.
