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.

A starting point here would be to take a look at the results from European New Car Assessment Programme (Euro NCAP) tests which were performed on both of the cars, with the same number of safety stars gained in the process. Still, apart from the official crash test results there are other things we need to be aware of. 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, taking kerb weight as an important factor into account, Sonata offers a marginal difference of 4% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Hyundai does have a slight advantage, at least on all of the models level. 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 4.2 out of 5. The same official information place Sonata as average reliability-wise, and Magentis is more or less at the same level.We should definitely mention that owners of cars with the same powertrain 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.

Hyundai 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. I believe that, when we take all into account, we have only one winner here - the Hyundai. In any case that's my personal view, built upon all the data available to me. What should decide here though is the way you feel about the two vehicles, and I hope you'll find my guidelines useful in the process.
