Kia Optima (2016-2020) Pros and Cons

Pros	Cons
Good value as a used buy	Dull to drive
Roomy interior	PHEV loses some boot space
Good EV range in plug-in hybrid	Earlier diesels could be more refined

Quick Summary

The Kia Optima (2016-2020) is a practical and well-equipped saloon that offers exceptional value in today's SUV-dominated market. Available as both a four-door saloon and five-door Sportswagon estate, it provides spacious interiors with 505 litres of boot space in the saloon and 552 litres in the estate. The car is well-made with solid materials throughout, featuring a touchscreen infotainment system with satnav on all models and comprehensive standard equipment that rivals more expensive competitors. All models benefit from timing chains rather than belts, reducing long-term maintenance costs.

The Optima is comfortable and absorbs poor road surfaces well, though it leans noticeably in corners and lacks sharp steering. Engine options include a 1.7-litre diesel (later replaced by a more refined 1.6-litre version), a 2.0-litre turbocharged petrol in the GT model, and a plug-in hybrid offering excellent electric range for town driving. Real-world fuel economy from the diesel engines reaches the low 50s mpg, whilst the plug-in hybrid provides significant savings for regular charging. Kia's excellent reliability reputation and factory warranty coverage on many used examples make this a sensible choice for budget-conscious buyers seeking a spacious, well-equipped alternative to SUVs.

Best for: Budget-conscious buyers seeking a spacious saloon or estate, those wanting excellent value over premium badge appeal, and drivers interested in plug-in hybrid technology for town commuting.

Not ideal for: Enthusiasts prioritising sharp handling and engaging driving dynamics, or buyers seeking the refinement of premium German rivals.


Comparison vs Key Rivals



The Verdict

You should buy the Optima if: You're seeking excellent value, a spacious and well-equipped saloon or estate, or interested in plug-in hybrid technology for economical town driving.

Consider alternatives if: You prioritise sharp handling and engaging driving dynamics, or desire the refinement and prestige of premium German rivals.

Competitive Position: The Kia Optima (2016-2020) represents outstanding value in the used saloon market, offering more space and equipment than many rivals at a lower price point. Whilst it lacks the driving engagement of the Ford Mondeo or the premium feel of the Volkswagen Passat, its combination of practicality, comfort, reliability, and affordability makes it an excellent choice for budget-conscious buyers. The plug-in hybrid variant adds another dimension, providing genuine savings for those with regular charging access. With SUVs commanding premium prices, the Optima saloon and Sportswagon estate offer significantly more car for considerably less money, making it a highly sensible purchase.
