Hyundai and Kia Outline Future Drivetrain Technology


Hyundai and its sister brand, Kia outlined their future powertrain development strategy that includes a new family of gasoline and diesel engines, developments in plug-in hybrid and electric drivetrains, and a next-generation fuel cell vehicle.

Hyundai showed off the first 4 engines and 2 transmissions from its upcoming “Smart Stream” powertrain family. With Smart Stream, Hyundai is aiming for improved fuel economy and reduced exhaust emissions.

The Smart Stream powertrains is Hyundai’s response to global changes in environmental regulation while still meeting customer demand for fun-to-drive cars. The word ‘Smart’ implies being smart in design, control, and operation, while ‘Stream' refers to dynamic movement of mobility.

Smart Stream technology optimizes the existing powertrain structure, with engine components reduced in size and weight to enhance fuel efficiency. With the advanced combustion techniques of Smart Stream engines, Hyundai Motor Group aims to maximize thermal efficiency by up to 50 percent.

Among the Smart Stream technologies include the first commercial application of Continuously Variable Valve Duration (CVVD) technology. In the Smart Stream G 1.6 turbo engine, the opening and closing of the cylinder valve is timed to best respond to various driving modes, such as eco-driving or dynamic driving.

Other new technology includes the Smart Stream eight-speed wet Dual-Clutch Transmission (DCT). Unlike conventional automatic transmissions, the dual-clutch system enables optimal shift response, with the eight-speed gearing and high-efficient hydraulic system delivering both faster acceleration performance, and excellent fuel economy at the same time.

By 2022, Hyundai Motor Group aims to develop an all-new Smart Stream powertrain line-up composed of 10 gasoline engines, six diesel engines, and six transmissions.

While combustion engines will remain a cornerstone for the brand until 2025, Hyundai and Kia will also produce a greater proportion of plug-in hybrids and electric powertrains. The shift to produce more alternative powertrains is coupled with plans to enhance battery capacity and increase the electric-only range capabilities of its electric models.

Finally, the Hyundai Motor Group will continue its development of Fuel Cell Electric Vehicles. The next FCEV from Hyundai Motor Group will have a driving range of 800 kilometers, a maximum power output of 163 horsepower, and the largest hydrogen storage density of any Fuel Cell vehicle on the market.
