Hyundai Motor Co. and its corporate cousin Kia Motors Corp. said Wednesday they will triple the number of green cars in their vehicle lineup to 22 by 2020.

The two companies, flagships of Hyundai Motor Group, the world's fifth-largest automotive conglomerate, said they will seek to field hybrid, plug-in hybrid, electric and fuel cell vehicles, ranging from small mini passenger cars to SUVs in the coming years.

By enhancing performance in all areas, Hyundai and Kia will aim to become the world's second-largest manufacturer of eco-friendly cars by the target year, up from fifth place this year, the company said. Toyota currently leads the green car sector, having the best selling Prius as one of its models.

Industry analysts have predicted that demand for eco-friendly cars will jump to 6.4 million units in 2020 from 2.2 million this year.

"The goal is to create a unique, eco-system for green cars and expand into new markets by tackling rivals head on," the South Korean automotive group said. 

Under the master plan, the number of hybrid electric vehicles (HEVs) will be increased to 12 from four, with six plug-in hybrid electrics vehicles (PHEV) to be sold on the market in six years from none at present.

It added that two new electric vehicles (EVs) will be reaching show windows around the world by 2020 to replace the current Ray and Soul EVs, while two fresh fuel cell electric vehicles (FCEV) will replace the current Tucson fuel cell model. 

Hyundai and Kia said that the new cars will be developed to have the latest batteries, top-notch range and excelling driving characteristics.

The group has already said they will release the Hyundai Sonata HEV 2015 model before the end of the year, with a compact and SUV models to follow suit in 2015. It will also reveal its first-ever PHEV next year.

In addition, Hyundai and Kia, taking their cues from Japanese and European carmakers, will launch a dedicated HEV that is different from all other cars in its line-up. 

This car, to be released next year, will not only look different but have its own dedicated engine and transmission setup that will give it best-in-class fuel mileage. 

In the EV and FCEV areas, Hyundai and Kia said they plan to capitalize on the advantages they have by making cars with longer range and by incorporating more technologies.

Hyundai has the world's first mass market fuel cell car in the Tucson, while Kia's Soul has the best range of any EV, with the exception of the much more expensive Tesla model electric cars. The Soul EV has been rated by Seoul to travel 148 kilometers on a single charge.

The companies, moreover, said they will invest heavily in research and development in the eco-friendly car market that will help boost their overall competitiveness and brand equity.

"The goal is to play a role in making green cars popular among people and to develop key components such as motors, battery packs and inverters that will give the South Korean companies an edge," a group official said.

He said the two companies have the capability to make components "in-house" since 95 percent of all parts that go into the Tucson FCEV are made in South Korea in cooperation with partners. (Yonhap)
