Replacing the ageing and out of style Credos model, the Optima is also sold in different regions as the K5, the Magentis and the Lotze.
It's a mid-size car like the more popular Chevrolet Malibu and Toyota Camry, an important sector of cars for manufacturers due to its large sales potential.
Originally the first-generation Optima did not sell well and a lot of the blame can be put down to its terrible safety rating given to it by the IIHS.
It only scored 1 out of 5 stars, let down by the side and seat safety tests - the outdated styling didn't help either - the only good point about the car was the small price tag.
With the introduction of the second-generation Optima the platform was massively upgraded helping the safety rating rise to 5 out of 5 stars with NHTSA, 4 out of 5 with EuroNCAP and a massive improvement to 3 out of 5 stars with IIHS.
Sales moved upward slightly but it wasn't until the third-generation car entered showrooms that the sales quadrupled.
Thanks to the move to the Hyundai Sonata platform, a near-perfect safety score and a serious improvement in the company's image buyers were queuing up for the new Kia Optima.
Now in its fifth-generation, the car is offered with a range of new safety aids such as blind-spot-detection and collision-avoidance-assist to help it keep its incredible safety rating.
