The 2015 Kia Optima saloon is now on sale in the UK, with prices starting from £21,495.
Kia's fourth-generation Optima was first seen in US specification at the New York motor show in April, with the European version making its debut at the Frankfurt motor show in September.
This new Optima saloon is marginally longer, taller and wider than the previous version, and the wheelbase has been stretched by 25mm. Kia says this allows for increased passenger space and luggage room, with rear passengers receiving a 25mm increase in leg room, as well as more shoulder room. Overall storage space has also increased, from 505 litres in the old Optima to 510 litres in the new version.
The new Optima is also stiffer than the outgoing version, with more than 50% of the body made from high-strength steel. Other advances include increased use of carbonfibre-reinforced plastic, with the aim of reducing weight in order to lower the levels of noise and vibration. The model will be available with 16, 17 and 18in alloy wheels.
While the US variant of the Optima will be built in Georgia in the United States, the car heading to the UK will be built in Korea.
