Hyundai Motor has recently announced the introduction of a new “hybrid dedicated” 1.6 litre Kappa GDI engine as well as an eight-speed automatic transmission slated for use in its future front-wheel drive (FWD) models. On the subject of the new engine, we can expect Hyundai’s Prius-rivalling AE hybrid to be the one of the first few models to be equipped with said mill – the engine will arrive in 2016, the same time as the AE.

According to Hyundai, the new 1.6 litre GDI Kappa engine is “designed to to boost power, performance and fuel economy, while driving down production costs and CO2 emissions in the growing mid-class hybrid electric vehicle (HEV) and plug-in hybrid electric vehicle (PHEV) segments.”

It marks the first time the company has produced an engine that combines the Atkinson cycle, cooled exhaust gas recirculation (EGR) technology and a long stroke specification for optimum thermal efficiency. As a result, the new engine is said to register a 3% improvement in terms of fuel efficiency and an engine thermal efficiency rating of 40%.

The new engine features a “six-hole laser-drilled GDI injector” along with a high-pressure fuel injection system (maximum 200 bar) to ensure maximum performance with reduced emissions and lower fuel consumption. As a result, the new mill pumps out a total of 105 PS and 147 Nm of torque.

Moving on, the Korean carmaker has also revealed its new eight-speed automatic transmission for its future FWD models – said gearbox is expected to serve alongside Hyundai’s Lambda, Theta turbo GDI, and R family of engines. The new eight-speed auto is said to boast 7.3% drop in fuel consumption over the current six-speeder. Overall weight has also been reduced by 3.5 kg over the older transmission.

Improvements over the current six-speed unit comes courtesy of an additional clutch over the aforementioned gearbox. Also, a direct control valve body that enables “solenoid control of the clutch directly rather than via several valves” reduces oil leakage and improves shift operations.
