In Hyundai Motor Group Blog I got the information that Hyundai/Kia Motor Group developed CVVD technology.

The original News article(dated 3rd July)  here : HMG

CVVD means “Continuously Variable Valve Duration”
Hyundai states that it’s developed for the first time in the world. This new technology improves engine performance remarkably and they will apply it to Hyundai/Kia cars.

On 3rd July, Hyundai/Kia held a presentation about their new technology in Goyang Hyundai Motor Studio
