At upcoming Los Angeles and Detroit auto shows, Kia will roll out new vehicles, and is now studying the option of expanding its North American production base – a move that might include the addition of a second U.S. assembly plant. Kia is now the fastest-growing brand in the U.S. market, noted Kia Motors America sales chief Tom Loveless, with a 78% sales surge since 2008 surpassing even Korean sibling Hyundai, as well as fast-track brands like Volkswagen and Subaru.
