Honda's CVT uses a steel belt. Firstly, most current CVT transmissions adopt steel belt drive systems. This transmission method can alter gear ratios by adjusting pulley sizes and can handle greater torque. Honda's CVT steel belts are primarily developed in-house, with their key feature being specialized compatibility with corresponding models. Durability comparison: CVT chains are generally less durable than steel belts. Primarily, CVT chains exert less impact on the cone pulleys, whereas steel belts have significantly lower strength compared to chains. Therefore, CVT transmissions using steel belts cannot withstand high torque. For instance, Nissan's CVT transmissions employ steel belts for power transmission and exhibit relatively higher failure rates. Although steel belts may generate more noise, they can endure greater torque and demonstrate superior durability.

Toyota's CVT transmissions use either a steel belt or a chain, depending on the specific model. For example, the 1.2T gasoline-powered Corolla and Levin use a steel belt CVT, where the belt is made of multiple thin steel layers, providing smoother power delivery suitable for small-displacement engines. However, models like the Camry 2.0L or RAV4 2.5L hybrid use a chain-type CVT because the chain can handle higher torque. I once disassembled a friend's older Levin and clearly saw the steel belt structure—the mechanic mentioned this design has lower repair costs. Toyota's differentiation is mainly based on engine power requirements: steel belts are sufficient for small displacements, while chains are more reliable for larger engines.

The answer depends on which model you're referring to, as different vehicles have varying configurations. Most 1.5L, 1.8L naturally aspirated or small-displacement turbocharged models like the Yaris and C-HR gasoline versions use belt-type CVTs, which have simpler structures, lower costs, and provide smooth, fuel-efficient driving. However, vehicles with engines above 2.0L displacement, such as the gasoline-powered Avalon or Highlander Hybrid, typically employ chain-type CVTs that can handle greater torque. Having driven a chain-type CVT Camry, I noticed more direct power delivery during acceleration, though chain noise is slightly more noticeable during cold starts. Both designs have their advantages, and Toyota engineers select the most suitable solution based on engine parameters.

CVT transmissions come in two types: steel belt and chain. The steel belt is primarily used in low to medium torque models, such as the Corolla 1.5L three-cylinder version, composed of hundreds of steel plates and rings, offering quiet and smooth operation. The chain type is more common in high torque models, like the 2.0L C-HR, which uses metal chain links for transmission. In actual driving, the steel belt CVT provides more comfort in traffic jams, while the chain CVT delivers more power when climbing hills. Toyota's newly developed Direct Shift-CVT in recent years also incorporates a launch gear, combining the advantages of both AT and CVT transmissions. In terms of maintenance, steel belt replacements are cheaper, whereas chains are more durable but come with higher repair costs.

As someone who has driven seven models, I can tell you: Toyota's CVT isn't a one-size-fits-all standard. Small-displacement cars like the Vios and Yaris mostly use belt-type CVTs, which are compact and fuel-efficient, making them ideal for city commuting. However, models with engines over 1.8L, such as the Camry 2.5G gasoline version, employ chain-type CVTs capable of handling over 240 Nm of torque. Here's an interesting detail: the E-CVT in Toyota hybrids actually uses a planetary gear structure, completely different from traditional belt/chain systems. In terms of durability, belt-type CVTs dislike aggressive driving while chain-types fear poor maintenance. Regular transmission fluid changes are recommended - both CVT types can easily surpass 200,000 kilometers.

Toyota's CVT transmission method varies depending on the vehicle's positioning. Economy models like the Corolla Cross use a belt-type CVT, which employs two sets of tapered wheels to clamp the steel belt for gear shifting, offering low cost and fuel efficiency. Performance-oriented vehicles such as the Crown Kluger 2.0T version utilize a chain-type CVT, where the metal chain provides higher transmission efficiency. Based on data comparison, the belt-type can withstand up to around 250 Nm, while the chain-type can handle over 300 Nm. In terms of driving feel, the belt-type offers smoother operation, whereas the chain-type responds more quickly. However, newer models like the Levin 1.8L hybrid use the THS system, which is essentially a planetary gear set—neither belt nor chain—achieving fuel consumption as low as 4L/100km.
