The Seoul Motor Show will kick off on March 29 for its 11-day run at KINTEX in Goyang, Gyeonggi Province, concentrating this year on eco-friendly fuel-cell and electric cars.
Five Korean and 20 foreign carmakers will bring products to the event, many of which are being shown for the first time.
Hyundai's concept sports car HND-9 and truck Trago will make their world premieres alongside Ssangyong's concept car LIV1 and passenger car Chairman W Summit. The Chairman will be mass-produced this year.
Fifteen models will make their Asia premieres, including four Korean designs such as the Hyundai i20, which will participate in the World Rally Championship in 2014, and 11 foreign cars like the Volkswagen Golf A7.
Of luxury brands, Maserati is taking part for the first time this year.
In addition, 18 models will make their Korean debuts. On the list are five domestic cars, like the Chevrolet Spark electric car by GM Korea, and 13 foreign models including the Mercedes-Benz A-Class, Toyota RAV4 and Lexus New IS.
"This year's show is the largest ever, with 331 auto and parts makers from 13 countries displaying their products. So the area of the exhibition has expanded two-fold compared to 2011," the show's organizing committee said.
