Are kia and hyundai engines the same?

Y’all …I’m curious about something. Are Kia and Hyundai engines basically the same? I’ve heard they’re related companies, so I’m wondering if they share a lot of the same parts, including their engines. Can anyone shed some light on this?

When I was shopping for a new car a few years ago, I test-drove both a Kia Optima and a Hyundai Sonata. I noticed that the driving experience was strikingly similar between the two. Later, when I took the Kia to my local mechanic for a routine check, he mentioned that many of the engine components were nearly identical to those in Hyundai models he’d serviced. This piqued my interest and led me to do some research on the connection between Kia and Hyundai.

Kia and Hyundai are indeed related companies, with Hyundai owning a significant stake in Kia Motors. As a result, they share a lot of technology, including engine designs and other key components. While each brand has its unique styling and specific tuning, many of their engines are built on the same platforms and use similar parts. This collaboration helps both brands reduce costs and improve reliability across their vehicle lineups.

Kia and Hyundai are affiliated companies within the Hyundai Motor Group. While they share technologies and platforms, their engines differ in design and specifications.
