Hyundai released a rendering of a four-door concept model to be unveiled at the upcoming Geneva Motor Show, called the i-flow. The car is designed based on the company’s ‘fluidic sculpture’ design language, the same the created the amazing 2011 Sonata. So it features a curvy and aerodynamic design. The i-flow is a preview of how future D-segment sedans by Hyundai would look like. If only their hatchbacks were so good!
