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 5-door wagon 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 100hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 101hp engine designed by General Motors.

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 same number of safety stars gained in the process. Moving further on, let's take a closer look at some additional safety-related facts. 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. Furthermore, if we'd like to consider vehicle mass in this context too, which we definitely should, the Korean car offers a marginal difference of 1% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Hyundai does have a slight advantage, when all the models are taken into account. These are the official statistics, while our visitors describe reliability of Hyundai with an average rating of 4.5, and models under the Opel badge with 4.2 out of 5. The same official information place i30 as average reliability-wise, and Astra is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as the Korean car rank it on average as 4.1, while the one under the competitor's bonnet gets 5.0 out of 5.

Hyundai is undoubtly more agile, reaching 100km/h in 1 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 181 kilometers per hour, 4km/h less than the other car. When it comes to fuel economy an obvious choice would be the German car, averaging around -0.2 liters of fuel per 100 kilometers (-1413 mpg), in combined cycle. That's 1% difference compared to the Korean car!

Opel 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 Hyundai 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. 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.
