Hyundai outlines future powertrain strategy

Hyundai Motor Group this week outlined its latest powertrain technologies and future plans at the 12th Hyundai-Kia International Powertrain Conference, held near the Hyundai Motor Group R&D Center in Korea.

  • Gasoline. In keeping with the trend to downsizing, Hyundai has been expanding the application of Turbo Gasoline Direct Injection (T-GDI) engines. While its compact(1.6L) and mid-size(2.0L) models are already equipped with such engines, Hyundai said it would continue efforts to improve T-GDI technology to develop small, yet strong engines, which can offer drivers driving pleasure.

    Diesel. In terms of diesel engine, Hyundai plans to continue expanding its diesel line-up based on the technology of the existing U, R and S engines.

  • Transmissions. Hyundai will continue its efforts to develop light-weight and fuel-efficient transmissions. The first automaker to develop an 8-speed auto transmission for the rear wheel drive vehicle in-house, Hyundai is focusing on developing transmissions for premium models as well.

  • Localization. Furthermore, Hyundai will offer more customized powertrains in response to local conditions to boost its overseas sales. For example, while Hyundai plans to increase the ratio of T-GDI engine-equipped models in its major markets including the US and China, it also plans to introduce flex-fuel engines for countries better suited for them. For countries with extreme weather conditions, Hyundai will provide engines that deliver sustainable performance regardless of changes in temperature.

Hyundai displayed the Kappa 1.0 TCI engine, Kappa 1.2 T-GDI engine, Gamma 1.6 T-GDI engine, Nu 2.0 CVVL engine, Theta 2.0 T-GDI engine, U2 1.1 WGT diesel engine, Euro 6 R 2.0 diesel engine and the Kappa CVT (Continuously Variable Transmission) to showcase its advanced powertrain technology.

The Kappa 1.0 TCI engine (Turbocharger Intercooler) delivers maximum power of 106 ps and maximum torque of 137 N·m (14.0 kgf.m, 101 lb-ft), and emits less CO2 than its original gasoline model.

A variety of technologies were adopted to maximize fuel economy and performance of the Kappa 1.0 TCI engine including 12-valve DOHC, integrated turbocharger and offset crankshaft. In addition, aluminum cylinder block, plastic intake manifold and head cover reduced the total weight while the ladder frame decreased NVH.

Around 1,000 powertrain experts and academics participated in the conference, including members from Bosch, Continental, Delphi, Magna Powertrain and Denso. Topics presented included next-generation gasoline technology, exhaust and after-treatment technology, diesel innovation technology, exhaust reducing technology, high efficiency transmission and improving driving experiences.
