Hyundai on Thursday unveiled plans to roll out 31 eco-friendly models by 2020, including hybrids, electric and hydrogen-powered cars.
The goal is to bolster the automaker's current lineup of 14 eco-friendly cars to become the world's No. 2 in the field.
The carmaker said it will unveil an electric version of the Kona small SUV in the first half of next year that is capable of running up to 390 km on a single charge.
Hyundai also wants to develop an electric car that can run up to 500 km on a single charge and release an electric version of the Genesis luxury sedan in March next year.
It also offered a glimpse of a hydrogen-powered SUV it plans to release in March next year.
The midsize SUV will be able to travel 580 km on a filling and have a price tag of some W79 million (US$1=W1,138).
Hyundai and affiliate Kia have sold more than 100,000 eco-friendly cars so far this year.
According to the Korea Automobile Manufacturers Association on Wednesday, Hyundai and Kia sold 17,314 eco-friendly cars both in Korea and abroad last month, bringing cumulative sales for the year amounted to 105,169.
Hybrid cars accounted for 85.8 percent at 90,508, followed by electric vehicles at 12,089, plug-in hybrids at 2,378 and fuel-cell EVs at 194.
Sales of the Hyundai Ioniq hatchback, which was rolled out late this year, are expected to rise even further after the model was rated most fuel-efficient car by the U.S. Environmental Protection Agency at 24.6 km per liter. Sales of EV and PHEV models are rising steadily. The proportion of EVs rose from just three percent in 2014 to 11.7 percent this year.
Hyundai plans to release an electric SUV capable of traveling 320 km in a single charge sometime next year, raising hopes of more eco-friendly cars on the roads.
Government agencies and a growing number of businesses are increasing the number of charging stations, which is expected to make EVs more attractive to reluctant motorists.
