Virtual Adviser's™ opinion
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 KIA being a large family car and the Hyundai representing luxury car vehicle class.
SafetyBoth vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the same number of safety stars gained in the process. That aside, let's consider some other aspects which affect safety. The second 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, when it comes to weight, a factor that most people underestimate, Sonata offers a marginal difference of 4% more metal.
ReliabilityReliability is not the best thing to consider on the make level, but it is worth mentioning that Hyundai does have a slight advantage, when all the models are taken into account. These are the results of an independent reasearch, while our visitors describe reliability of KIA with an average rating of 4.6, and models under the Hyundai badge with 4.5 out of 5. Independent research findings rank Magentis as average reliability-wise, and Sonata 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.
Performance & Fuel economyThere's not enough data for me to elaborate on the subject, I'm affraid.
Verdict
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. 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.
