Hyundai has taken the wraps off its new hybrid Kappa 1.6-litre GDI engine hat is most likely to be housed in the company’s upcoming Prius rival.
The new Kappa 1.6-litre direct-injection four-cylinder petrol motor (above) has been engineered specifically with hybrid and plug-in hybrid setups in mind.This is the first engine from the Korean car maker to feature Atkinson cycle, cooled exhaust gas recirculation and a long stroke design all in one.
Kappa 1.6-liter GDI engine is designed to boost power, performance and fuel economy while driving down production costs and CO2 emissions in the mid-class hybrid electric vehicle (HEV) and plug-in hybrid electric vehicle (PHEV) segments.Unveiled at the company’s annual International Powertrain Conference, the new mill pumps out a total of 105 PS and 147 Nm of torque. 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.
Also, Hyundai showed off a brand new 8-speed automatic transmission for front-wheel drive vehicles. The company claims it improves efficiency by about 7.3 percent when compared to the current 6-speed transmission used by the Korean car maker. Overall weight has also been reduced by 3.5 kg over the older transmission. By increasing the gear span with a more number of gears, the transmission offers improved acceleration performance at the low gear range, and enhanced fuel economy and NVH at the high gear range. 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.
The new eight-speed automatic transmission will accompany all its future FWD models, Lambda, Theta turbo GDI, and R family of engines
