What does 8AT mean?
2 Answers
8AT means an automatic transmission with 8 forward gears. AT stands for Automatic Transmission, also known as automatic gear. More information about automatic transmissions is as follows: 1. Automatic transmissions have the advantages of being easy to operate, comfortable to drive, and reducing driver fatigue. 2. An automatic transmission consists of a torque converter, planetary gear transmission, and control mechanism. It can automatically change speed and torque according to road conditions, reducing the difficulty of driver operation. 3. The advantages of automatic transmissions are mature technology, reliability, and generally comfortable shifting. The disadvantages are complex structure, higher maintenance and repair costs, and higher fuel consumption. 4. Automatic transmissions require regular maintenance. Depending on the manufacturer, the transmission fluid generally needs to be replaced at 40,000 kilometers or 60,000 kilometers.
8AT refers to an 8-speed automatic transmission, which simply means the car has 8 forward gears to choose from when shifting automatically. This type of transmission offers many benefits. More gears mean smoother shifts, allowing the engine to maintain a more fuel-efficient RPM. Having driven many cars, I've found that with the same displacement, an 8AT typically consumes about 10% less fuel than a 6AT. Structurally, it uses planetary gear sets and a torque converter, making it less prone to jerking compared to dual-clutch transmissions. On highways, it's particularly noticeable—the 8 gears keep the engine running around 1500 RPM, making the cabin very quiet. However, repairs can be expensive; a friend recently spent nearly 2,000 yuan just to change the transmission fluid. Overall, 8AT is now standard in high-end cars, striking an excellent balance between comfort and fuel efficiency.
