Hyundai has been making cars that preform very well in crash tests. Most automakers have only "acceptable" results for the small frontal overlap, but Hyundai managed consistently to have "Good" scores here, and its carried over to their named Genesis line. Its the hardest test to perform well in, but they're acing it.
Obviously the Koreans are putting in the necessary engineering to build something safe, and thats the most important fact of design. A strong frame comes before drive train or even body styling.
They can throw in any engine, put turbos on it, give it a stock DCT box from one of the big vendors, and it'll be quick. They can stuff in the latest MR suspension and give it impeccable ride quality and handling. Interior quality and comfort is a cakewalk when you have a competent design team. All of this is easy, they've already shown they can do the hard part.
They're gunning for big market share gains. In a few years Genesis will be a bonafide luxury brand competing with Lexus.
