Hyundai has unveiled breakthrough engine technology that will save fuel as well as reduce harmful emissions.

Described as a world first, Continuously Variable Valve Duration (CVVD) will feature in future Hyundai and Kia vehicles.

The first engine to get the new technology wil be the 1.6-litre four cylinder turbocharged Smartstream G1.6 T-GDi.

The valve control technology regulates the duration of valve opening and closing based on driving conditions, with a 4 per cent boost in performance and 5 per cent improvement in fuel efficiency.

Perhaps more importantly, it cuts harmful engine emissions by 12 per cent.

The first model to get the new Smartstream G1.6 T-GDi engine will be the Hyundai Sonata Turbo, set for introduction in the second-half of this year.

It also features Low-Pressure Exhaust Gas Recirculation (LP EGR) to further optimise fuel efficiency.

The new engine produces 134kW of power and 265Nm of torque in this form, compared with the current unit that is good for 130kW/265Nm.

“The development of the CVVD technology is a good example how Hyundai Motor Group is strengthening our powertrain technology,” President and Head of Research and Development Division at Hyundai Motor Group, Albert Biermann, said.

“We will continue our innovation efforts to bring forth paradigm shifts and ensure sustainability of our business model.”
