Does Hyundai CVT transmission use a steel belt or a steel chain?
2 Answers
Hyundai CVT transmissions use a steel belt. The functions of a transmission are: 1. To change the transmission ratio to meet the traction needs under different driving conditions; 2. To enable reverse driving; 3. To interrupt power transmission to the drive wheels when the engine starts, idles, shifts gears, or needs to stop for power output. Taking the Verna 2020 1.4L Manual GL Renewal Edition as an example: This car is manufactured by Beijing Hyundai, classified as a subcompact car, and uses gasoline as its energy type. The dimensions of this car are 4300mm in length, 1705mm in width, and 1460mm in height, with a wheelbase of 2570mm. It features a 5-speed manual transmission and is a 4-door, 5-seat sedan.
Modern CVT transmissions primarily use steel belts rather than steel chains, which makes me quite curious why mainstream models opt for this choice. The steel belt consists of multiple thin steel plates, transmitting power through thrust, differing from the pulling method of traditional chains, offering higher efficiency and a more compact structure. I've driven many CVT cars, brands like Honda and Toyota all use steel belts, providing smooth acceleration without jerking and being particularly fuel-efficient. Steel chains were once used in Audi's older Multitronic models, but due to high costs and frequent issues, they've been largely phased out in modern times. If you're concerned about durability, steel belts can last a long time with proper maintenance—regularly changing the transmission fluid is key, and avoiding aggressive throttle inputs to prevent overheating is advisable. New materials may emerge in the future, but for now, steel belts remain an economical and reliable choice.
