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 mpv segment and utilize the same 5-door MPV body style and the front wheel drive system, it all comes up to the specific diesel engine choice they offer. The first one has a General Motors-engineered powertrain under the hood, a 4-cylinder, 16-valves 110hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 128hp engine designed by Hyundai.

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 Opel being a slightly better choice apparently. Still, apart from the official crash test results there are other things we need to be aware of. Both vehicles belong to the mpv segment, which is generally a good thing safety-wise, but that fact doesn't break the tie between the two cars. Furthermore, if we'd like to consider vehicle mass in this context too, which we definitely should, the German car offers a marginal difference of 1% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that both brands display similar results in faults and breakdowns, when all the models are taken into account. These are the official statistics, while our visitors describe reliability of Opel with an average rating of 4.2, and models under the KIA badge with 4.6 out of 5. Independent research findings rank Meriva as average reliability-wise, and Soul is more or less at the same level.Above it all, drivers of cars with the same engine as the German car rank it on average as 3.6, while the one under the competitor's bonnet gets 4.0 out of 5.

KIA is undoubtly more agile, reaching 100km/h in 1.7 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 180 kilometers per hour, 5km/h less than the other car. When it comes to fuel economy the winner has to be the German car, averaging around 3.8 liters of fuel per 100 kilometers (74 mpg), in combined cycle. We can't ignore that 32% difference compared to the Korean car.

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, the German car offers much better overall protection, which launches it ahead of the other contender. From there things take a different direction, with KIA being considerably quicker, thus putting more smile on driver's face. It does come at a cost though, and that's the fuel consumption... All together, there's not much more to say, in this case I wouldn't even consider anything but Opel. 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.
