Introduced in 2000, the first-generation Kia Optima was essentially a rebadged Hyundai Sonata. Only minor exterior styling details and equipment packages set it apart from its Hyundai sibling. The sedan arrived in U.S. dealerships for the 2001 model year with a V-6 engine under the hood. A redesigned, second-gen model was launched in 2005. The new Optima differed further from the Hyundai Sonata it was based on. The vehicle was slightly larger and received a wide range of four-cylinder and V-6 engines. The Kia Optima was revamped yet again for the 2011 model year. Now sharing its underpinnings with the Hyundai i40 , the third-gen Optima saw the introduction of Kia’s new design language, which included the already familiar "tiger nose" front grille and "ice cube" LED headlamps. A huge success for Kia, the third-gen Optima will retire after the 2015 model year to make way for a redesigned sedan.
A fourth-generation Optima is already being tested in Germany, according to our spy photographers, who have supplied us with a preliminary set of photos. Naturally, the mid-size sedan is camouflaged to the teeth, leaving very few details for us to ogle at. Read on to find out what we know so far.
