The Kappa 1.6 litre GDI engine was developed by Hyundai to be fitted in their upcoming hybrid models. The company has also unveiled a new front wheel drive 8 speed automatic transmission.
Hyundai Motor wants its future hybrid models to be highly efficient; therefore the automaker is developing new technologies to match that goal. At the International Powertrain Conference, Hyundai unveiled the new 1.6 Kappa litre GDI engine designed to improve performance, fuel economy and to achieve lower CO2 emissions. The engine will take its place in Hyundai’s upcoming hybrid-electric and plug-in electric cars. Arriving in markets early 2016, the new unit with a power of 105 PS and 147 Nm torque marks the company’s first combination of the Atkinson cycle, cooled exhaust gas recirculation (EGR) and a long stroke specification to maximize thermal efficiency. The EGR system applied to the engine helps to recirculate exhaust gases back into the cylinder and burns them again. The new Kappa HEV engine alone delivers a 3% gain in fuel economy.
Alongside with the new engine, Hyundai has also unveiled a new front-wheel drive 8-speed automatic transmission which improves fuel economy by 7.3% when compared with the existing 6-speed automatic one. The new transmission is based on a new layout, with an additional clutch over the 6-speed unit. By increasing the gear span with a more number of gears, the transmission comes with an improved acceleration performance at the low gear range, and enhanced fuel economy and NVH at the high gear range. The weight has also been reduced by 3.5 kg from the 6-speed automatic transmission. Hyundai is targeting the large and luxury car segments, therefore the new transmission will be available on Lambda, Theta turbo GDI, and R family engines.
