Two significantly similar cars, no doubt about that. Still, each one has something different to offer. For a start, they are not even classified under the same segment, with the Hyundai being a luxury car and the KIA representing large family car vehicle class.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the same number of safety stars gained in the process. Moving further on, let's take a closer look at some additional safety-related facts. The first vehicle is a luxury car and that gives it a marginal advantage over the large family car competitor, at least that's what statistics show. Furthermore, if we'd like to consider vehicle mass in this context too, which we definitely should, Sonata offers a marginal difference of 4% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Hyundai does have a slight advantage, when all the models are taken into account. That's the official data, while our visitors describe reliability of Hyundai with an average rating of 4.5, and models under the KIA badge with 4.6 out of 5. Independent research findings rank Sonata as average reliability-wise, and Magentis is more or less at the same level.Above it all, drivers of cars with the same engine as these two vehicles rank it on average as 4.7 out of 5.

There's not enough data for me to elaborate on the subject, I'm affraid.

KIA appears just a bit more reliable, although the difference is truly marginal. The most important thing when deciding between any two vehicles should always be safety, both passive and active. In my opinion, everything taken into account, Sonata offers significantly better overall protection, taking the lead here. When it comes to performance, both vehicles provide similar experience, so I wouldn't point any of them out. Fuel consumption is more or less the same. It's really tough to make a final decision here, but if I'd need to, I'd say Hyundai. Nevertheless, let's not forget that people have different preferences and needs, so what really counts is your personal feel. I'm only here to help.
