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 well-equipped and practical saloon or Sportswagon estate, offering a strong alternative to the popular SUV trend. While it competes with established rivals like the Ford Mondeo and VW Passat, its generous interior space, including 505 litres of boot space in the saloon (552 litres in the Sportswagon, 440 litres for the PHEV), and solid build quality make it a compelling used buy. All models feature a user-friendly touchscreen infotainment system with satnav, and higher trims boast advanced safety features and premium sound systems.

Driving dynamics prioritise comfort over sportiness, soaking up road imperfections effectively, though steering can lack sharpness. Engine options include a refined 1.6-litre diesel (replacing an earlier 1.7-litre), a 2.0-litre turbo petrol in the GT model, and an economical plug-in hybrid with significant real-world range. Running costs are reasonable, with diesels achieving low 50s mpg, and all engines featuring timing chains for reduced maintenance. Kia's excellent reliability and long warranty coverage add further appeal to this practical family car.

Best for: Drivers seeking a spacious, well-equipped, and reliable family car at a good used price, especially those considering a frugal plug-in hybrid for urban driving.

Not ideal for: Buyers prioritising engaging driving dynamics, those needing maximum boot space in a PHEV, or those sensitive to engine refinement in earlier diesel models.

While it may not offer the most engaging driving experience compared to some rivals, its practicality, robust standard equipment, and the availability of an economical plug-in hybrid make it a strong contender.
