What does 8AT transmission mean?

Here is the meaning of 8AT transmission: 1. An 8AT transmission is an automatic transmission with 8 forward gears. The increased number of gears allows for a closer gear ratio, enabling the vehicle to operate at more appropriate gear positions, reducing engine speed and fuel consumption. In terms of automatic transmissions, the evolution has progressed from conventional automatic transmissions to those incorporating manual operation modes, and further to continuously variable transmissions (CVT) and dual-clutch transmissions. 2. 8AT transmissions are generally found in high-end models. Many premium products from brands like BMW, Audi, and Land Rover use ZF's 8-speed automatic manual transmission, commonly referred to as the ZF transmission. The first domestic brand to adopt the ZF 8AT transmission was the H8 and H9 series under the Haval brand.

I usually enjoy studying automotive technology. The 8AT transmission actually stands for an 8-speed automatic transmission, where AT represents automatic transmission, meaning it's the type of transmission that doesn't require clutch pedaling and shifts gears automatically. It has 8 forward gears, which is several more than the older 4AT or 5AT transmissions. The advantage is that the car shifts gears very smoothly, with almost no noticeable jerking. When driving on the highway, the engine can run at lower RPMs, which not only saves fuel but also makes the ride quieter, reducing fuel consumption by about 10% to 15%. Some new cars from brands like BMW or Toyota use 8AT because it can intelligently match driving conditions, such as quickly downshifting to boost power during rapid acceleration or providing smoother performance when climbing hills. However, this technology is quite advanced, utilizing complex electronic control components and sensors, so repairs can be expensive if it malfunctions. But once you get used to it, it's hard to go back to transmissions with fewer gears!
