Reports on Automotive News have indicated this will be a change targeted at the American market at first, where they still call the Hyundai i45 and i30, the Sonata and Elantra.
In a recent interview, Hyundai Motor Co. Vice Chairman Chung Eui-sun said the company is considering a change which would adopt their local badges. The current Kia range in South Korea is named in K-series form - K3, K5 and K7 etc.
Although there are no definite plans, Chung Eui-sun said he understands American buyers seem to prefer a car with a name, but he also thinks alphanumerics can increase the brand's strengths in the market. And, well, what do you think; are you more likely to buy the upcoming Optima as an 'Optima' or as a 'K5'?
