The Hyundai brand is quickly becoming a name to be considered amongst other major Continental giants of the motoring industry. Thanks to their constant strive to research and develop their models, we are beginning to see more and more of their vehicles on Malaysian roads. We had the opportunity to test out their latest 2019 Hyundai Santa Fe yesterday and here are our first impressions of it. (more…)
VVT (Variable Valve Timing), VTEC (Variable Valve Timing & Lift Electronic Control), VVT-i (Variable Valve Timing with intelligence), i-VTEC (intelligent VTEC), Dual VVT-i, CVVT (Continuously Variable Valve Timing) are all familiar valvetrain systems in today’s cars. Now the Hyundai Motor Group (HMG) adds a new one – CVVD or Continuously Variable Valve Duration (CVVD).
The world first technology, first mentioned at HMG’s International Powertrain Conference in October 2017, is being revealed at the Hyundai Motorstudio Goyang in Korea this morning. The Smartstream G1.6 T-GDi will be the first engine to have the technology and it will be used in future Hyundai and Kia models.
CVVD optimizes both engine performance and fuel efficiency while also being eco-friendly. The valve control technology regulates the duration of valve opening and closing according to driving conditions, achieving a claimed 4% boost in performance and a 5% improvement in fuel efficiency, while cutting toxic emissions by 12%.
How CVVD works
Typical variable valve control technologies manage the timing of the valve’s opening and closing (as in CVVT) or control the volume of air admitted by adjusting the depth of the opening (Continuously Variable Valve Lift – CVVL). Previous variable valve control technologies could not regulate valve duration, as the valve’s closing timing was subordinate to opening timing and could not respond to diverse driving situations. CVVD takes the technology in a new direction by adjusting how long a valve is open.
When the vehicle is maintaining a constant speed and requires low engine output, CVVD opens the intake valve from the middle to end of the compression stroke. This helps to improve fuel efficiency by reducing the resistance caused by compression. On the other hand, when engine output is high, such as when the car is driving at a high speed, the intake valve is closed at the beginning of the compression stroke to maximize the amount of air used for combustion, enhancing torque to improve acceleration.
Smartstream G1.6 T-GDi Engine
Unveiled alongside the new CVVD technology, the new Smartstream G1.6 T-GDi Engine is a V4 turbocharged petrol unit with 180 bhp/265 Nm output. Besides using the Group’s new CVVD technology, it also features Low-Pressure Exhaust Gas Recirculation (LP EGR) to further optimize fuel efficiency.
Additionally, the new unit has an Integrated Thermal Management System that quickly heats or cools the engine to an optimal temperature, and a strong direct spray system that achieves 350 bar, surpassing the 250 bar of the previous T-GDi engine. In addition, engine friction is reduced by 34% with the application of low friction moving parts.
“The development of the CVVD technology is a good example how HMG is strengthening our powertrain technology,” said Albert Biermann, President and Head of Research & Development Division at Hyundai Motor Group. “We will continue our innovation efforts to bring forth paradigm shifts and ensure sustainability of our business model.”

300 lucky motoring enthusiasts will be receiving invites for a very special ‘N Homecoming’ hospitality experience at the 2019 Nürburgring 24 Hours Race. The sad news is that the invites will only be from countries that sell N vehicles where Malaysia is not a part of…yet. (more…)
Hyundai Motor Group is upping their tech game with the introduction of the world’s first performance control for commercial EV complete with the ability to determine the gross weight of light duty commercial electric vehicle and optimizing their performance. (more…)
Let’s face the facts and just prosper on the fact that the future of mobility is already here and thriving on a magnificent scale. Hyundai has done so with open arms and guess what? They just launched an electric double-decker bus of their very own.
The first-of-its-kind from Hyundai is part of the company’s effort in the goal of reducing traffic congestion and more importantly, air pollution. Making its public debut at the Land, Infrastructure and Transport Technology Fair in South Korea, it is a huge deal for Hyundai as the was co-hosted with the national Ministry of Land, Infrastructure and Transport.

The folks from Hyundai Motor Company (HMC) and Hyundai-Sime Darby Motors (HSDM) are currently ironing out all the final details in bringing the Hyundai Nexo, the brand’s flagship hydrogen fuel cell powered crossover SUV, into the Southeast Asia market. This was announced following the sale of two units of the vehicle to Sarawak Energy Berhad aka “Sarawak Energy”. (more…)
The all-new 2019 Hyundai Santa Fe (the same one that was previewed during the Kuala Lumpur International Motorshow 2019) is officially available starting today and there will be four different variants available for those who are interested. (more…)
Hyundai Motor Group has just announced their latest development for their vehicle’s interior air quality. The Intelligent Air Purification System or ‘Smart Air Purification System’ is an innovative in-car filter that works automatically to provide ‘excellent’ air quality using advanced technology.
Using their latest filtration technology, this new system is able to remove around 99% of fine particulates even before passengers enter the vehicle and throughout the journey. The results have been so positive that the system might make its way to all future Hyundai and Kia models to promote better health in highly congested urban areas. (more…)
