What does 8AT mean?
2 Answers
8AT refers to a hydraulic automatic transmission with 8 forward gears. There are four common types of automatic transmissions in cars: hydraulic automatic transmission (referred to as AT), continuously variable transmission (referred to as CVT), automated manual transmission (referred to as AMT), and dual-clutch transmission (DCT). The following is an introduction to hydraulic automatic transmission: Hydraulic automatic transmission (AT) is a type of automatic transmission. Taking the most common planetary gear type as an example, its principle is to achieve automatic shifting through the combination of hydraulic transmission and planetary gears. It generally consists of a torque converter, planetary gear mechanism, shift execution mechanism, shift control system, shift operation mechanism, and other components.
8AT refers to an 8-speed automatic transmission in vehicles. I've driven many cars equipped with this type of transmission, which is designed with 8 forward gears to make the shifting process smoother. The advantage of more gears is that the engine can maintain a more appropriate RPM at different speeds, improving fuel efficiency and significantly reducing jerky sensations while driving. In daily use, such as during city traffic jams or highway cruising, the automatic shifting responds quickly, providing a more comfortable driving experience. In terms of maintenance, 8AT is relatively reliable—just regular transmission fluid changes are needed, and it's less prone to long-term failures compared to older transmissions, making it much more hassle-free. Overall, this is a key technological advancement that enhances driving quality.
