The ix35 Fuel Cell Electric Vehicle (FCEV) will begin in-service testing this year with plans to put it into production by 2015.
Hyundai's third-generation FCEV is equipped with a 100kW fuel cell system, with two high pressure, 700bar hydrogen storage tanks.
The ix35 FCEV can travel 650km on a single charge, a range equal to a conventional petrol-powered car. It can be started in temperatures as low as minus 25 degrees Celsius.
The ix35 FCEV's range is a 76-percent improvement over the previous generation which was limited to 370km on one charge.
This new model achieves a petrol equivalent fuel efficiency of 3.2 litres per 100km, a 15-percent improvement over the previous generation.
The overall volume of the fuel cell system has been downsized by 20-percent, via modularisation of bulky parts including the fuel cell stack, balance of plant (BOP), inverter and the high voltage junction box.
This year 48 of the ix35 FCEVs will be part of a Domestic Fleet Program supported by the South Korean government.
To date, Hyundai has registered more than 2 million kilometres of testing of its hydrogen vehicles.
Hyundai plans to build a limited volume of the ix35 FCEVs in 2012 and begin mass production in 2015.
