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.
Describe Hyundai IVT.
The brand name for Hyundai’s CVT, or continuously variable gearbox, is Hyundai IVT, which stands for Intelligent Variable Transmission. The IVT enhances fuel efficiency and lowers engine power loss while successfully simulating the sensation of gear shifting with a traditional automatic transmission. To enhance power delivery and lessen the possibility of slippage and abrupt gear shifts, it has a chain belt system.
With its SmartStream IVT Chain-driven Unit, Hyundai presents a novel interpretation of the conventional CVT.
The continuously variable gearbox, or CVT, is a kind of non-manual transmission that has been popular over the past ten years across a variety of automakers’ models. With its brand of Xtronic CVTs across its range, Nissan has nearly completely replaced the conventional automatic transmission.
In contrast to conventional cars, the CVT distributes power using two pulleys connected by a belt, increasing efficiency while enhancing the driving experience because no shifting takes place.
However, one of a CVT’s main weak spots is the CVT belt. As a result, when Hyundai launched its own vehicle in 2020, the SmartStream IVT, it completely did away with the belt. Instead, a chain belt joins the two pulleys so that power from the company’s series of SmartStream engines may be distributed.
The so-called “intelligent variable transmission,” according to Automacha, adjusts the pulley diameter by using the tension in the chain to do so. This eliminates slippage and increases the efficiency of power delivery.
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.
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.
What distinguishes an IVT from a CVT transmission?
IVT is claimed to be able to mimic the shift pattern of a manual transmission, making it feel more responsive even though it is quite comparable to a Continuously Variable Transmission (CVT). IVT, created and manufactured by Hyundai Transys, replaces the traditional metallic belt with a chain belt.
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.
In the meantime, the second-generation K3 is currently equipped with the very fuel-efficient new CVT. The new CVT features exceptional responsiveness and performance that makes driving enjoyable by tailoring the gear shift patterns to the driver’s intentions and driving circumstances. Additionally, it has the first metal chain belt in its market segment, which guarantees gains in durability and efficiency.
The catalog offers 5-, 6-, 10-, and 12-speed manual transmissions for automobiles, SUVs, buses, and commercial trucks. As environmental regulations have become more stringent in recent years as a result of worldwide movements for sustainable transportation, the company’s expertise in producing such a wide range of transmissions has become increasingly valuable. Significant additions to Transys’ offering include powertrains for hybrid, plug-in hybrid, electric, and hydroelectric cars. In contrast to the somewhat one-dimensional catalogs of the rivals, this broad portfolio definitely shines out. Of course, as is the case with every industry leader, the company’s rising status is only feasible thanks to tireless labor behind the scenes. We went to the Hyundai Transys Powertrain R&D Center in Hwasung, South Korea, to talk with the engineers there about these initiatives.
IVT vs. automatic transmission: Which is superior?
Compared to conventional automatic gearbox, the IVT offers improved fuel efficiency and a smoother, more responsive drive on the road. Similar to a continuously variable gearbox, an IVT executes continuous shifts while you are driving your car.
IVT transmission—does it have gears?
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.
Does Hyundai produce its own gears?
It’s also intriguing that Hyundai manufactures the majority of its own transmissions. Hyundai TRANSYS, a Hyundai company, is the manufacturer of these transmissions. This business was actually made up of two distinct entities called Hyundai DYMOS and Hyundai Powertech. These two businesses united on January 1st, 2019, to form Hyundai TRANSYS.
Prior to it, Hyundai’s automatic transmissions were made by Hyundai Powertech, which was established in 2001. Furthermore, it produced automatic transmissions for Jeep, Dodge, and Kia.
Hyundai received manual gearboxes from Hyundai DYMOS, which was established in 1994. These included Hyundai-specific DCT and AMT gearboxes. It’s also good to know that this company was in charge of making Hyundai’s seats, 4WD, and axles.
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.
