Does the Roewe i5 CVT transmission use a steel belt or a chain?
2 Answers
Roewe i5 CVT transmission uses a steel belt. There are two types of power transmission methods for CVT: one is a steel belt, and the other is a chain. Generally speaking, steel belts are usually suitable for low-torque engines, while chains are typically used for high-torque engines. In terms of actual performance, chains are undoubtedly more durable and resistant to wear. Below is some relevant information about CVT: 1. Introduction: CVT refers to a type of automotive transmission, also known as a continuously variable transmission. 2. Difference from stepped transmissions: The difference between CVT and stepped transmissions is that its gear ratio is not a series of discrete points but a continuous range of values, which achieves good fuel economy, power performance, and smooth driving experience, while also reducing emissions and costs.
I've been driving for many years and have carefully studied the CVT transmission in the Roewe i5, which uses a steel belt drive system. The steel belt consists of a series of thin steel plates linked together, continuously adjusting the gear ratio via two conical pulleys, providing an exceptionally smooth driving experience without any jerking. While chain drives are more durable, they're typically used in high-horsepower or higher-cost models like SUVs or performance cars. The i5 is positioned as an economical family sedan, paired with a 1.5L engine, where the steel belt is lighter and more energy-efficient, keeping fuel consumption low at around 6 liters in city driving. With long-term use, as long as the transmission fluid is changed on time and inspected every 40,000 kilometers, the steel belt shows minimal wear and few issues. Compared to chains, steel belts are lower in cost and simpler to maintain, though they have slight limitations during high-speed acceleration. Overall, the i5's choice of a steel belt CVT is quite reasonable, offering a stable, comfortable, and worry-free driving experience.
