The Kia K4 Sport+ is the higher-equipped non-turbo K4 grade, sitting above Sport and below GT-Line. Key buyer features include synthetic leather-appointed trim, added convenience features, Kia safety technology, 12.3-inch display technology and practical sedan or hatch body choices, so shoppers should compare S, Sport+, and GT-Line based on budget, body style, engine preference, comfort features and technology needs.
