Smooth speed change and superb acceleration with fast response
NVH performance improvement with the initial chain belt
HYUNDAI TRANSYS IVT provides a pleasant driving experience with smooth speed change, prompt acceleration and diverse speed modes regarding the driver’s intention and road conditions for dynamic driving. It improved optimal delivery efficiency, durability and NVH performance with the first application of a metal chain in the same segment.
The IVT structure has been changed from rubber V belt type to metal type. Metal V-belt type IVT with chain belt, which has been mass-produced since 2010, is excellent at delivery efficiency, but weak at NVH due to a different operation mechanism. There is a limitation on applying this type to large size SUV because customers of SUV are not sensitive to NVH. For the first time in the world, HYUNDAI TRANSYS installed the IVT in medium-size vehicles (28kgf.m) and improved efficiency and NVH performance. Drivers can experience cost-effectiveness and a powerful driving force.

01
Chain belt
The best transmission ratio range achievement and NVH performance improvement in the same segment with the application of a new chain belt contributed to fuel efficiency.
IVT uses two pulleys with a steel belt running between them, unlike the common transmissions that have gears attached to each other. IVT does not have any gears but has only two pulleys that are connected to the engine and driveshaft, respectively controlling the diameter of each pulley. The highest functioning transmission ratio and chain belt in the same segment are applied for improved NVH performance, and separating springs maximize delivery efficiency.
02
Separating spring
Delivery efficiency improvement through Brake dragging loss prevention
IVT uses two pulleys with a steel belt running between them, unlike the common transmissions that have gears attached to each other. IVT does not have any gears but has only two pulleys that are connected to the engine and driveshaft, respectively controlling the diameter of each pulley. The highest functioning transmission ratio and chain belt in the same segment are applied for improved NVH performance, and separating springs maximize delivery efficiency.
03
High-efficient vane pump
Noise reduction and delivery efficiency improvement with the application of non-coaxial vane pump
IVT uses two pulleys with a steel belt running between them, unlike the common transmissions that have gears attached to each other. IVT does not have any gears but has only two pulleys that are connected to the engine and driveshaft, respectively controlling the diameter of each pulley. The highest functioning transmission ratio and chain belt in the same segment are applied for improved NVH performance, and separating springs maximize delivery efficiency.

Centrifugal pendulum-type (CPA) torque converter
Direct solenoid valve and low leakage design implementation
IVT uses two pulleys with a steel belt running between them, unlike the common transmissions that have gears attached to each other. IVT does not have any gears but has only two pulleys that are connected to the engine and driveshaft, respectively controlling the diameter of each pulley.
