Overview

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 city car segment and utilize the same 5-door hatchback 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 109hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 87hp engine designed by Opel.

Safety

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the KIA 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 city car segment, which is generally not a very good thing 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, the German car offers a marginal difference of 2% more metal.

Reliability

Reliability is not the best thing to consider on the make level, but it is worth mentioning that both brands display similar results in faults and breakdowns, all the models observed together. These are the results of an independent reasearch, while our visitors describe reliability of KIA, as well as Opel, with the same average rating of 4.2 out of 5. Some independent research have also placed Rio as average reliability-wise, and Corsa 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 4.3, while the one under the competitor's bonnet gets 3.7 out of 5.

Performance & Fuel economy

KIA is a bit more agile, reaching 100km/h in 0.4 seconds less than its competitor. In addition to that it accelerates all the way to 183 kilometers per hour, 3km/h more than the other car. When it comes to fuel economy the winner has to be the German car, averaging around 4.3 liters of fuel per 100 kilometers (66 mpg), in combined cycle. We can't ignore that 19% difference compared to the Korean car.

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, the Korean car offers slightly better overall protection and takes the lead. It all continues in the same 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... It's really tough to make a final decision here, but if I'd need to, I'd say 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.
