What does 8AT transmission mean?
3 Answers
8AT transmission refers to an automatic transmission with 8 forward gears. The increased number of gears allows for a closer gear ratio in the transmission, enabling the vehicle to operate at more appropriate gear ranges, reducing engine speed, and decreasing 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. 8AT transmissions are typically found in high-end vehicle models, with many premium products from brands like BMW, Audi, and Land Rover utilizing ZF's 8-speed automatic transmission with manual mode, commonly known as the ZF transmission. The first instance of a domestic brand adopting the ZF 8AT transmission was in the H8 and H9 series under the Haval brand.
The 8AT transmission refers to an 8-speed automatic transmission, meaning the vehicle's gearbox has eight forward gears. It automatically shifts gears based on speed and engine RPM without requiring clutch engagement like a manual transmission. Having driven many cars before, I find this design makes gear shifts incredibly smooth, almost imperceptible. For instance, during highway cruising, it can maintain low RPM operation, reducing fuel consumption and noise. The benefits are numerous: fuel efficiency is the standout feature, saving one to two liters per 100 kilometers compared to 6AT or older 4AT transmissions; acceleration response is also quicker, enhancing driving comfort. However, there are drawbacks, such as higher potential maintenance costs due to its complex structure, especially common in luxury vehicles—like the latest BMW and Mercedes models adopting it to elevate overall smart performance. In summary, 8AT represents a technological advancement in modern automobiles, proving practical for both daily commutes and long-distance travel.
As an ordinary person who enjoys road trips, an 8AT transmission means easier and more comfortable driving for me. With 8 gears and computer-controlled shifting, it eliminates the hassle of manual gear changes, especially convenient in traffic jams. In practice, the acceleration is smooth, the engine noise is low, and it saves fuel costs in the long run, averaging 10% less fuel consumption than a regular automatic transmission. I recommend everyone to pay attention to this when buying a car, especially for SUVs and mid-size sedans, because the multiple gears optimize power delivery, making it more powerful when climbing hills or overtaking. But don't just focus on the advantages; if there's an electrical issue, repairs might take more time, so regular maintenance is key. Compared to a CVT continuously variable transmission, the 8AT is stronger in durability and sportiness, and its popularity in modern cars is due to its balance between economy and comfort.
