Categories: Cylinder Head Tips

Hyundai’s latest Continuously Variable Valve Duration technology is the future of integrating technology into vehicle mechanics. Find out everything you need to know about Hyundai’s latest innovation!

The Hyundai Motor Group has taken the manufacturing world by storm with its announcement of developing the world’s first Continuously Variable Valve Duration (CVVD) technology. This breakthrough in the manufacturing and automotive world successfully improves a vehicle’s overall performance and economy without any compromises. With plans for it to be used in both Kia and Hyundai vehicles, this technology is an exciting development that will offer many benefits for future vehicle owners. Let’s take a look at what CVVD technology offers and the advantages and disadvantages of it.


History of CVVD Technology

Just over three years ago, Hyundai announced that they were introducing CVVD into their line-up of products. Through their newly launched CVVD technology, Hyundai aims to alter the valves and the way in which they operate within your engine. The technology was first unveiled to the world at Hyundai Motorstudio Goyang in 2019, where it was showcased with the Smartstream G1.6 T-GDi, which is the first engine that featured this technology. This engine can be found in vehicles such as the Hyundai Sonata Turbo, which was introduced later in 2019. It paved the way for future vehicles to use this solution and was the start of great things to come for the company.

What is Continuously Variable Valve Duration Technology?

Similar to a variable valve lift or a variable valve timing, CVVD manages the engine valve timing for opening and closing. Unlike the former technology, CVVD is able to offer adjustments to different types of driving scenarios. The CVVD is located within the head and alters how long the valve will stay open during a combustion cycle. This technology allows more air or less air to travel through the cylinder, which will be dependent on the engine’s rpm. It’s a very flexible solution that is continuously variable, manufacturers can optimize it to work best for the vehicle. Hyundai hopes it will increase economy and vehicle performance while also decreasing emissions by up to 12 percent.


Advantages of CVVD

When driving a vehicle with CVVD, you’ll notice that both fuel efficiency and engine performance are greatly improved. It can help to make your vehicle more eco-friendly, which is something that many of us are looking to do in this day and age. Drivers notice that performance increases by up to 4% and fuel efficiency can see an improvement of roughly 5% with CVVD. The technology regulates the valve opening and closing based on the driving conditions, offering a very flexible solution that can be added to a wide range of vehicle engines.


Disadvantages of CVVD

While the advantages of CVVD are quite impressive, there are of course going to be some drawbacks to any new technology. CVVD has gradually been applied to cars and engines over the years, but you’ll find that it’s still not widely used on the market today. This lack of adoption means that you may be limited with your choices of vehicles if this is something you really desire as an addition to your next car. Keep in mind that CVVD may also add to the price of the vehicle or engine due to the complexity of this technology. That being said, the benefits you’ll see that we shared above generally outweigh these disadvantages, which is why we recommend considering any vehicle with CVVD.


Cost of Vehicles with CVVD

As a consumer, you won’t necessarily notice the additional cost of CVVD in your vehicle purchase, but it’s certainly there. The first vehicle that offered CVVD as standard was the 2020 Hyundai Sonata. It came to the market at around $34,590 for the 2020 Sonata Limited, which offered drivers the CVVD engine. As you can imagine, vehicles with this option are generally a little pricier than similar options on the market due to the development and production costs associated with this technology.


Reviews of CVVD Vehicles

Reviews of CVVD-equipped vehicles are generally very favorable, and you’ll find that it offers great benefits to drivers. Drivers often state that they enjoy a smooth but efficient engine that provides maximum power thanks to the valve timings. The improved performance and reduction of exhaust emissions are something that any driver will appreciate. After some time, you’ll find that the amount of fuel you have to top up your vehicle also slightly decreases, thanks to the improvement in fuel efficiency.
