The Kia Optima has received a number of upgrades aimed at improving quality, refinement and safety and will go on sale in the UK in early 2014.

The Optima features new headlights, fog-lights and rear lights, as well as redesigned bumpers and wheels.

The LED daytime running lights have been moved to within the headlight assembly, and the fog-lights now feature a four-point LED design similar to that used on the Kia Proceed GT.

At the rear, the light clusters have been enlarged and feature surface-emitting LEDs, and there’s a new sharper-edged boot lid.

New 17-inch and 18-inch alloy wheel designs are available, as is a new Sport Pack which adds a black mesh grille, chrome trim around the lower air intake, a matt black rear diffuser and unique 18-inch double-spoke alloy wheels.

Inside, the instruments benefit from a larger 4.3-inch display with improved graphics, while the revised centre console receives a new 7-inch screen.

The seats have been improved with greater side support, and are now available with front ventilation and rear heating, while the rest of the interior benefits from increased sound-proofing, particularly in diesel models.

Although a 165PS 2.0-litre diesel is available in Europe, the UK will only receive the 1.7-litre 136PS diesel unit.  CO2 emissions are 133 g/km, but drop to 128 g/km when fitted with the optional stop/start system.  An automatic gearbox is available as an option.

Various safety systems are now also available, including blind spot detection, lane change assist and rear cross traffic alert.
