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 4-door sedan 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 Opel-engineered powertrain under the hood, a 6-cylinder, 24-valves 170hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 145hp engine designed by Hyundai.

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 large family car segment, which is generally a good thing safety-wise, still it doesn't help us solve our dilemma, does it? Furthermore, when it comes to weight, a factor that most people underestimate, the German car offers a marginal difference of 8% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Hyundai does have a slight advantage, at least on all of the models level. That's the official data, while our visitors describe reliability of Opel with an average rating of 4.2, and models under the Hyundai badge with 4.5 out of 5. The same official information place Vectra as average reliability-wise, and Elantra is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as the German car rank it on average as 5.0, while the one under the competitor's bonnet gets 4.7 out of 5.

Opel is a bit more agile, reaching 100km/h in 0.6 seconds less than its competitor. In addition to that it accelerates all the way to 230 kilometers per hour, 24km/h more than the other car. When it comes to fuel economy the winner has to be the Korean car, averaging around 8.2 liters of fuel per 100 kilometers (34 mpg), in combined cycle. We can't ignore that 20% difference compared to the German car.

Hyundai 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 slightly better overall protection and takes the lead. It all continues in the same direction, with Opel offering somewhat better performance, just enough to call it quicker. 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 Hyundai. 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. 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.
