Kia K5: engines, hybrid and trims
The Kia K5 is a mid-size sedan that has replaced the Optima in many markets since 2019. In Lithuania, it is most often imported from Korea or the USA. We look at how the previous and updated versions differ, which engines are offered, how the trims vary, and what to check before buying a used K5.
K5 in brief
The K5 (DL3) is Kia's mid-size sedan with a coupe-like silhouette, a wide front grille, and a more modern interior. In many markets, it replaced the Optima, and in Korea, the name K5 has been used since 2010.
The car is spacious and boasts a good amount of equipment for a reasonable price. In Europe, it was officially sold in limited numbers, so most of the cars seen on the market are imports.
Versions — what's the difference
Until around 2023, the first DL3 version was produced, after which the car was updated: the front and rear were changed, the interior and multimedia system were refreshed.
When choosing, pay attention to which market the car was sold in — Korean and US versions differ in engines, names, and equipment.
Engines and transmissions
The offered petrol engines are 2.0 and 2.5-litre naturally aspirated, 1.6-litre turbo, and the more powerful 2.5 turbo (in the GT version). In Korea, there is also a hybrid version and an LPG (dual-fuel) modification.
An automatic transmission is most commonly fitted, with 8 speeds in most variants. The drive is usually front-wheel, but all-wheel drive is available in some markets.
What to check when buying a used K5
Check the imported car's history using the VIN and request documents about previous repairs and accidents. Inspect the bodywork and paint thickness carefully.
Test the engine and gearbox — they should run smoothly, without any juddering. For LPG versions, make sure to check the system's condition and paperwork.
Check that all the electronics work, paying extra attention to the infotainment and assistance systems.

Frequently asked questions
Are the K5 and Optima the same?
The K5 replaced the Optima in many markets from 2019. The new-generation car is entirely new, so there's no reason to confuse it with earlier Optima generations.
Is the K5 available in Europe?
It wasn't widely sold in Europe, so cars spotted in Lithuania are usually imported from Korea or the USA.
Which engine is the best?
For most, the 2.0 or 2.5-litre naturally aspirated engine is the way to go for simplicity, while performance enthusiasts might prefer the 1.6 turbo or 2.5 turbo.
