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 large 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 136hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 170hp engine designed by Opel.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), 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 large family car 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 12% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Hyundai does have a slight advantage, all the models observed together. That's the official data, 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 i40 as average reliability-wise, and Insignia 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 4.6, while the one under the competitor's bonnet gets 3.0 out of 5.

Opel is undoubtly more agile, reaching 100km/h in 1.8 seconds less than its competitor. In addition to that it accelerates all the way to 215 kilometers per hour, 20km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 6.4 liters of fuel per 100 kilometers (44 mpg), in combined cycle.

Hyundai is apparently more reliable, not too much, but just enough. 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 significantly better overall protection, taking the lead here. It all continues in the same direction, with Opel outracing its opponent in any situation possible, making it better choice for boy racers. It does come at a cost though, and that's the fuel consumption... No mistake, whatever you decide here, but I'd still go for 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. In case you have two minutes to spare I invite you to define your needs, desires and budget and see which car would be chosen by the virtual adviser™, among thousands of similar, yet so different vehicles.
