Toyota RAV4 uses CVT (Continuously Variable Transmission) and eCVT (Continuously Variable Transmission) transmissions. Transmissions are divided into manual and automatic types. Manual transmissions mainly consist of gears and shafts, achieving speed and torque changes through different gear combinations. Automatic transmissions (AT) are composed of a torque converter, planetary gears, a hydraulic torque variation system, and a hydraulic control system, achieving speed and torque changes through hydraulic transmission and gear combinations. The Toyota RAV4 is the base model in Toyota's compact multi-purpose off-road vehicle family, with dimensions of 4265mm in length, 1785mm in width, 1705mm in height, and a wheelbase of 2660mm.

The RAV4 at my home is the gasoline version, equipped with a CVT transmission, also known as a continuously variable transmission. It drives very smoothly with no noticeable jerks during gear shifts, making it particularly suitable for city commuting. It also features a simulated 8-speed function, providing quick acceleration response on highways, though the engine noise is slightly louder when climbing hills. Compared to other SUVs, it has high fuel efficiency, with an average fuel consumption of around 8 liters, which is quite economical for ordinary families. The four-wheel-drive version also uses the CVT and has good off-road capability. I remember the older RAV4 models might have used traditional automatic transmissions, but the new models have all been upgraded to this. Maintenance is simple, requiring only a transmission fluid check every two years. Overall, it's quite durable—I’ve driven it for several years without any issues. Toyota products are just reliable.

From a technical perspective, the RAV4's transmission varies by version: gasoline models mostly come with a Direct Shift-CVT continuously variable transmission, while the hybrid version uses an e-CVT, which is essentially an electronically controlled transmission system. The principle of CVT involves achieving continuous gear shifting via a steel belt and pulleys without fixed gears, offering seamless shifting that automatically optimizes engine RPM for improved fuel efficiency. The e-CVT in hybrids is more advanced, integrating motors and engines to coordinate operations, such as delivering strong acceleration when fully charged. This design reduces component wear and minimizes long-term issues, unlike older automatic transmissions that require frequent maintenance. The RAV4's 4WD system is also compatible with these transmissions, ensuring stable off-road performance. Owners are advised to perform regular maintenance and avoid excessive loads to prolong lifespan.

Absolutely love the RAV4's transmission system! The latest gasoline models all come with a CVT continuously variable transmission, simulating 8 gears for a silky-smooth driving experience, especially powerful when overtaking on highways. The hybrid version is even cooler, utilizing e-CVT technology that relies on a planetary gear mechanism to distribute power, making it almost silent during driving while also being fuel-efficient. Compared to earlier models that might have used 4-speed or 6-speed automatic transmissions, Toyota has upgraded the entire lineup since introducing this generation's platform, resulting in significant performance improvements. This type of transmission is highly adaptable, maintaining stable fuel consumption whether in city traffic jams or suburban adventures. Toyota has put in the effort on reliability, requiring minimal major repairs and featuring extended oil change intervals. Having test-driven it multiple times, I feel the steering and acceleration are perfectly matched, making it a genuine recommendation for tech-savvy car enthusiasts.
