Meanwhile, Kia said on Monday it has released a revamped version of its K5 midsize sedan with an improved value proposition and a suite of feature upgrades.

The latest K5 features expanded safety and convenience options across its trims, with Kia adding a new entry-level trim called Smart Selection to the 2-litre gasoline engine model, offering a more affordable price point.

Kia has also standardised features, such as LED lighting on the sun visor and glove box, rear-seat floor mat hooks and an in-car fire extinguisher on all trims.

Starting from the Prestige trim, previously optional features like steering wheel vibration alerts and steering wheel heating are now standard.

A Kia official stated, "This year's updated model has significantly enhanced safety and convenience features, incorporating extensive customer feedback on the previous year's product improvement model to further elevate its competitive edge."
