Well, these are two pretty similar cars we have here! It's only details that could potentially make the difference. Considering they both belong to the small family car segment and utilize the same 4-door sedan body style and the front wheel drive system, it all comes up to the specific petrol engine choice they offer. The first one has a Hyundai-engineered powertrain under the hood, a 4-cylinder, 12-valves 90hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 88hp engine designed by Mazda.

Unfortunatelly, neither of the two vehicles was submitted to the European New Car Assessment Programme (Euro NCAP) testing. This makes it virtually impossible for me to pick one over the other and I'm generally against buying such cars as the safety should really always come first. Still, apart from the official crash test results there are other things we need to be aware of. Both vehicles belong to the small family car segment, which is generally classifying them somewhere in the middle safety-wise, but it doesn't do much to help us decide between the two. On the other hand, if we'd like to consider vehicle mass in this context too, which we definitely should, Sephia offers a marginal difference of 7% more metal.

Reliability 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 Hyundai with an average rating of 4.5, and models under the KIA badge with 4.6 out of 5. Unfortunatelly, I don't have enough insight that would allow me to comment in more details on the specific models level. That apart, owners of different cars powered by the same engine as Accent rank it on average as 3.0 out of 5, exactly the same as the other one.

Hyundai is undoubtly more agile, reaching 100km/h in 1.3 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 169 kilometers per hour, 11km/h less than the other car. When it comes to fuel economy the winner has to be Accent, averaging around 6.4 liters of fuel per 100 kilometers (44 mpg), in combined cycle. We can't ignore that 23% difference compared to Sephia.

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, Sephia offers slightly better overall protection and takes the lead. From there things take a different direction, with Hyundai being considerably quicker, thus putting more smile on driver's face. To make things even better, it consumps less fuel! All together, there's not much more to say, in this case I wouldn't even consider anything but 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. In case you have two minutes to spare I invite you to define your needs, desires and budget and see which car would be chosen by the virtual adviser™, among thousands of similar, yet so different vehicles.
