The seats both front and rear are comfortable whether they were covered in cloth or leather, the latter trim feeling like a decently thick and waxy hide. There’s plenty of seat adjustment for the driver, too, and even with a six-footer up front, leg room in the back is exceedingly generous.
On the equipment front there are three trims to choose from for both the saloon and sportswagon, with the PHEV getting its own trim.
Choose the entry-level 2 trimmed Optima and you will find 17in alloys, electric windows, heated and folding door mirrors, hill start assist and parking sensors on the outside, while inside there is dual-zone climate control, reversing camera, Bluetooth, DAB radio, cruise control and USB ports in the front and rear.
Upgrade a level and it will adorn your Optima with 18in alloys, electrically adjustable driver’s seat, heated front seats and steering wheel and Kia’s safety technology, while the range-topping GT-Line S equips the car with a sporty bodykit, dual exhaust, rear diffuser and adaptive LED headlights on the outside, and luxuries such as rear sunblinds, ventilated front seats, heated rear seats, leather upholstery, a 360-degree camera and wireless phone charger on the inside.
The PHEV saloon gets its own trim level which includes adaptive LED headlights, dual-zone climate control, parking sensors, cruise control and a faux leather upholstery, alongside Kia’s fully-loaded 8.0in touchscreen infotainment system complete with 10-speaker Harman and Kardon stereo set-up.
Behind the wheel, you immediately notice the improved refinement of the diesel motor. You still get a bit of vibration through the floor, but there’s little to none coming through the controls.
Noise is also greatly reduced throughout the rev range; you do still hear it at higher crank speeds, but the tone is nowhere near as coarse as it is in other models using the same engine. Not only is it quieter but it also pulls meaningfully from as little as 1250rpm. It’s never brisk at 10.0sec to 62mph, but it is more than adequate almost all of the time.
