Is the CVT transmission of Mitsubishi ASX equipped with a steel belt or a chain?
2 Answers
The Mitsubishi ASX CVT transmission uses a steel belt for friction drive. The advantages of the Mitsubishi ASX CVT transmission include: 1. Smooth shifting without jerking: Since the CVT transmission has continuously variable ratios, there is no jerking. 2. Maintains the engine in the economical RPM range: Due to the continuously variable ratios and synchronization with vehicle speed, the engine RPM range is no longer restricted by changes in vehicle speed. Information about the CVT transmission is as follows: 1. Composition: The CVT mainly consists of two sets of pulleys (drive pulley and driven pulley), a transmission belt (steel belt), oil pump, torque converter, actuators (valve body, oil circuit), sensors, and a computer. 2. Power performance: The CVT can achieve closed-loop control with the engine, fully utilizing the engine's maximum torque. Its torque-increasing performance is significantly better than that of MT and AT transmissions. Therefore, when installed in SUV models that emphasize torque, the acceleration performance (0~100km/h) of CVT-equipped vehicles is 7.5%~11.5% better than AT vehicles, and high-speed acceleration performance is superior to MT vehicles.
I've driven many cars, especially Mitsubishi models, and the CVT transmission in the ASX is indeed belt-driven. Compared to chains, the belt is quieter and smoother, but it's more prone to wear, especially when you accelerate hard. I've seen many CVT failure cases at repair shops, mostly caused by belt slippage or breakage. The ASX uses this design mainly because it's cost-effective and fuel-efficient, providing smooth driving in the city, but long-term highway driving requires attention to maintenance. I recommend owners change the transmission fluid regularly, about every 40,000 kilometers, to prevent oil degradation from accelerating belt aging. Among my friends who own ASXs, several say they can last up to 100,000 kilometers without issues, provided there's no reckless modification or overloading. Another downside of belt-driven CVTs is the high repair cost—once it fails, you usually have to replace the entire unit. Overall, it's an economical and practical choice, suitable for daily commuting.
