Hyundai LPI Elantra Hybrid

Hyundai has begun receiving pre-launch orders for its Elantra LPI Hybrid Electric Vehicle, its first commercial hybrid in South Korea. Pre-orders will end July 7, a day before it officially introduces the car in the Korea domestic market.

The hybrid electric vehicle is powered by a Liquefied Petroleum Injected (LPI) engine. The LPI Gamma engine has a displacement of 1.6 liters, a 15kW (105 Nm) electric motor and a Continuously Variable Transmission (CVT).

Together, the engine emits just 99 g/km of CO2 and 90 percent fewer emissions than an equivalent standard gasoline powered Elantra to qualify as a Super Ultra Low Emission Vehicle (SULEV).

Liquefied Petroleum Gas (LPG), often referred to as auto gas, is a low carbon emitting hydrocarbon fuel which burns more cleanly than gasoline or diesel and is especially free of the particulates associated with the latter.

The hybrid engine is a mild (assist) hybrid, which should attain 17.8km/l (or gasoline equivalent of 22.2km/l). That's a 47 percent increase over the conventional 1.6L Elantra. Hyundai points out LPG in Korea is 50% less than that of gasoline, making it an even better option.

The electric motor will be powered by a lithium-ion battery pack, the first hybrid in the world according to Hyundai to adopt the lithium-ion polymer battery cells. The technology and all key components in the LPI HEV have been developed by Hyundai and its local partners including the motor, battery and low DC/DC converter.
