Is the Corolla transmission AT or CVT?
4 Answers
Corolla transmission is CVT. More information about AT and CVT is as follows: 1. AT is a hydraulic automatic transmission with a complex structure, consisting of a hydraulic torque converter, planetary gears, and a hydraulic control system, achieving speed and torque changes through hydraulic transmission and gear combinations. 2. CVT is a mechanical continuously variable automatic transmission, composed of two pairs of variable-diameter pulleys and a steel belt, connected to the engine and drive wheels respectively. During operation, speed can be changed by altering the diameter of the pulleys. 3. AT advantages: strong load capacity, high speed; AT disadvantages: high fuel consumption, complex structure. 4. CVT advantages: fuel-efficient and environmentally friendly, small size, low cost, simple structure; CVT disadvantages: low speed.
The Corolla uses a CVT transmission, which stands for continuously variable transmission, and this applies to most models, such as the 2023 version. I've driven it a few times, and it feels incredibly smooth, without the gear-shifting jerkiness you get with traditional AT transmissions. It's very fluid when accelerating. Fuel efficiency is one of its major advantages—it's noticeably more economical in city driving, saving about 1-2 liters per 100 kilometers compared to an AT. However, the engine noise is a bit louder during initial acceleration with a CVT, and some people complain about the humming sound, but you get used to it. I also recommend regular checks on the transmission fluid, changing it every 50,000 kilometers to avoid long-term dust buildup leading to system failures. Toyota's overall reliability is high, and a CVT can last seven or eight years without issues, making it worth considering.
The Corolla's transmission type is CVT, and its continuously variable structure allows for infinitely smooth gear shifts. I study automotive dynamics and understand that CVT uses a belt system to continuously adjust the gear ratio, unlike the gear shifting in an AT. This design keeps the engine operating within the optimal RPM range, making it more fuel-efficient and efficient. Toyota chose it because it maximizes energy efficiency, especially in congested road conditions. AT transmissions are more durable but slightly less fuel-efficient, and the Corolla's CVT requires attention to the cooling system to prevent overheating. Smooth driving also reduces gear shift shocks, which benefits the suspension system.
The Corolla mainly comes with a CVT transmission, which is quite fuel-efficient. When I was choosing a car, I experienced that the CVT is much smoother than an AT, saving fuel costs in city driving. Toyota does well in this aspect, with good reliability—just drive normally and you won't have much to worry about for ten years.
