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 Mazda-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 125hp engine designed by Opel.

The fact that the Opel got tested by the European New Car Assessment Programme (Euro NCAP), while the other contender didn't, isn't really an advantage, taken the poor 3-star rating it received. That aside, let's consider some other aspects which affect safety. Both vehicles belong to the mpv segment, which is generally a good thing safety-wise, but it doesn't do much to help us decide between the two. On the other hand, when it comes to weight, a factor that most people underestimate, the German car offers a considerable difference of 13% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that both brands display similar results in faults and breakdowns, 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 Opel badge with 4.2 out of 5. Independent research findings rank Carens as average reliability-wise, and Zafira is more or less at the same level.Above it all, drivers of cars with the same engine as the Korean car rank it on average as 5.0, while the one under the competitor's bonnet gets 4.7 out of 5.

KIA is a bit more agile, reaching 100km/h in 0.2 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 185 kilometers per hour, 3km/h less than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 8.6 liters of fuel per 100 kilometers (33 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 beats the other contender by far, making it the best choice without even considering other things. From there things take a different direction, with KIA offering somewhat better performance, just enough to call it quicker. Fuel consumption is more or less the same. No mistake, whatever you decide here, but I'd still go for 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.
