Hyundai Motor Company, South Korea’s largest automaker, has begun taking pre-launch orders for its Elantra LPI Hybrid Electric Vehicle (HEV), its first hybrid vehicle for commercial sale. (Earlier post.)
Hyundai will accept pre-launch orders until 7 July, a day before it officially introduces the car in the Korea domestic market. The car, which is the world’s first hybrid electric vehicle to be powered by a Liquefied Petroleum Injected (LPI) engine, was first unveiled at the 2009 Seoul Motor Show in April.
Powered by an LPI Gamma engine displacing 1.6 liters; a 15 kW (105 Nm) pancake type Permanent Magnet Synchronous Motor; and a Continuously Variable Transmission (CVT), the Elantra LPI HEV emits 99 g/km of CO2 and 90% fewer emissions than an equivalent standard gasoline-powered Elantra. It qualifies as a Super Ultra Low Emission Vehicle (SULEV).
The Elantra LPI Hybrid is a mild-hybrid with a fuel economy rating of 17.8 km/l (5.6 L/100km or 42 mpg US); gasoline-equivalent fuel economy is 22.2 km/l (4.5 L/100km, 51 mpg US). This represents a 47% improvement over a conventional 1.6L Elantra.
The Elantra LPI Hybrid energy storage systems uses a 180V, 5.3 Ah lithium-ion polymer battery (LIPB) pack (with cells from LG Chem) with forced air cooling. The cells uses a Mn-spinel cathode material, amorphous carbon anode and ceramic-coated separator.
Among the benefits of the battery, Hyundai says, are 65% more power density; 15% more energy density; 12% more energy efficiency; and 43% better state-of-charge estimation. More accurate SOC estimation makes it possible to expand the real operating SOC range, with a more diversified HEV driving strategy and improved cycle life.
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.
