Intelligent Variable Transmission is referred to as iVT. It is Hyundai’s most prominent in-house innovation. This cutting-edge transmission is seen in Hyundai vehicles. As the name implies, it adjusts the speed more intelligently than an automatic gearbox does “step-by-step.” In comparison to other transmission types, it makes the vehicle smoother and more responsive. Additionally, iVT enables the engine to operate in a sweet efficiency range as compared to conventional automatic transmissions. As a result, it contributes to increased fuel efficiency and good performance.
Intelligently Variable Transmissions are a particular category of automatic transmissions. It functions in a similar manner to an automatic transmission. The engine’s restricted speed range is automatically converted to a variety of ratios and sent to the driven wheels utilizing a number of different gears. During acceleration, the gear ratio needs to be adjusted numerous times by the typical automatic transmission. It shifts gears by momentarily severing the engine’s connection to the driveline to do this. The engine then re-engages after finishing. This caused a little slowdown in the car’s forward velocity, which the occupants could feel.

How does it function?
The new IVT conducts continuous shifts to offer greater economy than automated transmissions, very much like a continuously variable transmission. This is accomplished by changing the transmission’s pulley system’s pressure, which is adjusted in response to the driver’s input and road conditions. Its usage of a wide-ratio pulley system immediately correlates to a significantly wider range of operational ratios than many other, comparable transmission systems. This is what causes fuel efficiency to rise at higher gear ratios while performance at lower gear ratios improves.
Additionally, the IVT mimics the automatic transmission’s preferred gear shifts, giving the impression that you are still operating a vehicle with a 6AT. It is the first time this has ever been done in the compact car sector globally. The IVT also uses a chain belt rather than the far more typical push belt. This contributes once more to increased fuel efficiency.
Finally, the IVT aligns driver input, vehicle behavior, and acceleration using innovative Shift Control Strategy technology. It becomes more responsive as a result, which enhances the driving experience. Check out the 2020 Elantra or Accent for an IVT-equipped vehicle for the time being. We’re confident the IVT will eventually make its way to other models in the lineup.
Will an ivt or dct transmission perform better on highways?
Similar to a CVT (Continuously Variable Transmission), an IVT (Infinitely Variable Transmission) executes continuous shifts to outperform automated gearboxes in terms of efficiency. The IVT lines up driver input, vehicle behavior, and acceleration using innovative Shift Control Strategy technology. It becomes more responsive as a result, which enhances the driving experience. So if you want the best driving experience possible, you can choose IVT. Additionally, we advise you to take a test drive to evaluate its comfort and functionality.

What is the IVT’s mechanism? What distinguishes it from DCT?
on 18 Dec 2020
The CVT (Continuously Variable Transmission), also known as an IVT (Infinitely Variable Transmission), employs pulleys or belts to change gears. Instead of using steel gears, belts or pulleys produce variable gear ratios that are based on engine speed or RPM. This results in improved fuel efficiency and a smooth, jerk-free drive. The gearbox lag that occurs anytime you floor the throttle is a drawback for passionate drivers. The Honda City, Hyundai i20, and Maruti Suzuki Baleno are well-known vehicles with CVTs. A dual-clutch transmission (DCT), on the other hand, uses two distinct shafts, each with its own clutch, to change gears: one shaft for odd-numbered gears and the other for even-numbered gears. While providing good fuel economy, this kind of automatic transmission is completely performance-oriented and has a higher production cost as a result. They are also expensive to maintain if an issue emerges. In addition to being used in sports cars, this sort of transmission is now seen in more economical vehicles like the Kia Sonet and the Hyundai Creta.
Hyundai IVT: A CVT or not?
For better reaction and efficiency, the Hyundai iVT gearbox uses a continuously variable transmission based on a chain belt. A pair of expandable and retractable pulleys connected by a metallic belt enable the stepless change in ratios in a traditional continuously variable transmission (CVT) system.
Who makes the IVT transmission for Hyundai?
Through its associate firm, Hyundai Transys, the Hyundai Motor Group manufactures its own CVT, MT, DCT (dual-clutch), AMT (automatic manual), and four/five/six/eight-speed automatic gearboxes in South Korea. 2019 saw the merger of Hyundai Transys, Hyundai Powertech, and Hyundai DYMOS.
Hyundai IVT transmissions are they dependable?
Hyundai has been at the forefront of CVT development and manufacturing since since CVTs became more widespread in the middle of the 2010s. Hyundai has recognized the performance and economy potential of CVT transmissions, much like many other well-known automakers (Nissan, Honda, Toyota, etc.). With no interruptions, engine power, fuel, or loss of acceleration, CVT gearboxes provide smooth acceleration. In addition, they have a considerably more straightforward, compact, and lightweight design than a conventional hydraulic transmission or a direct-shift DSG transmission. They are therefore the ideal option for both small commuter cars and larger vehicles like crossover SUVs.
I dislike lengthy content, so let me summarize:
- Hyundai used to experience a lot of CVT-related issues, particularly failures at low mileage. By the end of 2020, most of these problems have been fixed. The IVT CVT transmission from Hyundai is regarded as being very dependable.
- To learn what can go wrong with a CVT transmission, see our article on the most typical CVT transmission issues.
- The CVT transmission fluid needs to be changed often to ensure smooth operation of the CVT gearbox.
Let’s move on from the advantages of the Hyundai CVT transmission and discuss the most frequent issues with this type of transmission.
What distinguishes IVT from CVT?
IVT (Infinitely Variable Transmissions) are a subset of CVT systems in which the ratio of output shaft speed to input shaft speed has a zero ratio that can be continually approached from a specified greater ratio.
IVT is a type of transmission, right?
The Kia Intelligent Variable Transmission (IVT) System is one of the brand’s innovations. This technology, which is a type of continuously variable transmission, ensures smooth gear shifts and offers excellent efficiency.
IVT: Does that mean manual or automatic?
Three engine options are offered for the Hyundai i20 2020: a 1.2-liter gasoline engine, a 1.0-litre turbo gasoline engine, and a 1.5-litre diesel engine. The 1.2-liter petrol engine is mated with a CVT/IVT transmission in the premium hatchback. The IVT (intelligent variable transmission), which conducts continuous shifts and is very similar to the CVT, is more efficient than automated transmissions.
In city traffic, CVT does really offer exceptional fuel efficiency and is also less taxing.
Is the ivt transmission dependable in congested city traffic and on inclines?
Which transmission is employed by Hyundai?
Hyundai Transys, the most famous powertrain manufacturer in Korea, offers a wide range of powertrains to differentiate itself in the global transmission market. In 2019, Hyundai Powertech and Hyundai Dymos merged to form the new company, which developed AT (Automatic Transmission) and CVT (Continuously Variable Transmission) and MT (Manual Transmission) and DCT. The two Hyundai affiliates merged in an effort to improve the effectiveness and efficiency of transmission manufacture, sales, and R&D. The early results seem encouraging. With its diverse comprehensive portfolio of AT, MT, DCT, CVT, and AMT (Automated Manual Transmission), Hyundai Transys has now established itself as the only company in the world capable of producing all types of transmissions in-house. This activity is driving the company forward in the worldwide market.
Unquestionably, one of Hyundai Transys’s greatest advantages is its extraordinarily broad product line. Large commercial vehicles, front-wheel-drive, rear-wheel-drive, and transmissions and reducers for special-class vehicles such K1A1 Tanks, ITX Saemaeul trains, KTX trains, and HEMU-430 are among the notable categories in the catalog. But the front-wheel-drive automatic transmission is by far the type with the most demand. The type, which comes in 4, 6, and 8-speed variations, is frequently found in both small and large cars, such as the Morning city car from Kia and the Grandeur luxury sedan from Hyundai. For more expensive vehicles, an 8-speed rear-wheel-drive transmission is also an option. The 8-speed RWD transmission is a cutting-edge technology used in Kia Stinger and Mohave, as well as Genesis G70, G80, and G90. It has outstanding power transfer efficiency and meets strict NVH regulations.
The 7-speed DCT is mostly found in small and compact cars, such the Hyundai i30, Tucson, and Veloster as well as the Kia K3 GT, Seltos, and Sportage. It has both the advantages of an automatic transmission and the convenience of an automatic transmission. These vehicles are ideal for the 7-speed DCT because one of their key selling features is their superb driving characteristics. The new 8-speed DCT from Transys, which outperforms the 7-speed in terms of performance and efficiency, will shortly go into full production.

Which is superior, the IVT, CVT, or DCT?
As it doesn’t allow gasoline go to waste during transmission shifts, DCT is the most efficient transmission type available. Contrarily, CVT isn’t too far behind and is also reasonably effective. Power to the wheels is not interrupted by the belt’s constant movement between the pulleys. Both CVT and DCT have good fuel economy; but, if you want a transmission that gives you an advantage, choose a DCT.
Which is preferable, IVT or DCT?
A dual-clutch transmission (DCT), also known as a twin-clutch transmission or double-clutch transmission, is an automated transmission in cars that is closely related to a manual transmission. An infinitely variable transmission (IVT) is a continuously variable transmission with an infinite ratio range, meaning that the transmission ratio may be zero. For odd and even gear sets, it employs two different clutches.

IVT is preferable for fuel efficiency whereas DCT is better for driving with a focus on performance.
The number of gears in an IVT transmission.
The gearing range of an endlessly variable transmission is equivalent to that of an 11-speed auto transmission. The Telam CVT is what is known as an infinitely variable transmission since it features both forward and reverse rotation as well as a built-in geared neutral.
