INCHEON -- GM Korea Co., the South Korean unit of General Motors Co., said Wednesday it will launch the GMC brand in the second half, with the Sierra Denali set to be released as the brand's launch model in the Korean market.

GM's decision to launch the GMC brand is part of the Detroit carmaker's multi-brand strategy in which the Korean unit produces compact SUVs in Korea and brings in large-sized SUVs and pickups from the United States.

GMC is GM's premium SUV and pickup truck brand. The Sierra Denali is a premium full-size pickup truck which was unveiled in Korea during a media event held in Incheon on Wednesday.

GM sells vehicles under four brands, Chevrolet, Cadillac, Buick and GMC, globally. Chevrolet and Cadillac models are currently available in Korea.

"Now, we are in the stage of a new chapter for GM in Korea, fulfilling our commitment made in 2018 and turning the spin towards growth with our confident strategy of strong export and multi brands in Korea," GM Korea Chief Executive Roberto Rempel said in a statement.

In 2018, GM vowed to keep its Korean operations running for at least the next 10 years and promised to introduce 15 models from 2018-2023 in exchange for fresh loans from the state-run Korea Development Bank (KDB), the second-biggest shareholder in GM Korea after GM.

The GMC brand will serve as crucial component of the multi-brand strategy in Korea, creating synergy with Chevrolet and Cadillac, Carlos Meinert, vice president in charge of sales, service and marketing at GM Korea, said.

GM Korea will continue to introduce new GM models to the domestic market along with the vehicles produced at its Bupyeong and Changwon plants, the statement said.

The company said it is "carefully" considering bringing in Cadillac's luxury electric vehicles such as the Lyriq and Celestiq to meet growing demand for zero-emission models in Asia's fourth-biggest economy.

The fifth-generation GMC Sierra shares the same platform as the Cadillac Escalade and Chevrolet Tahoe.

The Sierra Denali comes with a 6.2-liter gasoline engine that generates as much as 420 horsepower and a 10-speed automatic transmission.

Further details, including prices and specifications, will be released later.

In recent years, GM Korea has struggled with lackluster sales in South Korea due to lack of new models and the COVID-19 pandemic.

From January to May, GM Korea's sales fell 25 percent to 96,068 units from 127,907 a year earlier.

Its lineup is composed of four locally assembled models -- the Spark mini car, the Malibu sedan and the Trailblazer and Trax SUVs -- and five imported ones -- the Colorado pickup, the Bolt all-electric car and the Equinox, Traverse and Tahoe SUVs.

Most of the models currently sold in South Korea are from the Chevrolet brand. (Yonhap)
