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 petrol engine choice they offer. The first one has a Hyundai-engineered powertrain under the hood, a 4-cylinder, 16-valves 124hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 105hp engine designed by Opel.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the Opel being a slightly better choice apparently. Moving further on, let's take a closer look at some additional safety-related facts. 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. On the other hand, taking kerb weight as an important factor into account, the German car offers a marginal difference of 4% 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, at least on all of the models level. 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 Opel badge with 4.2 out of 5. The same official information place Carens as average reliability-wise, and Zafira is more or less at the same level.That apart, owners of different cars powered by the same engine as the Korean car rank it on average as 4.9, while the one under the competitor's bonnet gets 3.8 out of 5.

KIA is undoubtly more agile, reaching 100km/h in 2.7 seconds less than its competitor. In addition to that it accelerates all the way to 178 kilometers per hour, 2km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 7.2 liters of fuel per 100 kilometers (40 mpg), in combined cycle.

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... I believe that, when we take all into account, we have only one winner here - the Opel. Anyway, that's the most objective conclusion I could've came up with and it's based solely on the information found on this website. Aspects such as design, practicality, brand value and driving experience are there for you to measure them out. Also, you could use the oportunity to find out which car, everything taken into account, would be the perfect choice for you in the eyes of the virtual adviser™, among thousands of similar, yet so different vehicles.
