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 4-cylinder, 16-valves 147hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 145hp engine designed by Hyundai.

The first thing to look into here would be the results from European New Car Assessment Programme (Euro NCAP) tests performed on the two cars. Good thing is that both vehicles got tested, with the Opel 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 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. Furthermore, when it comes to weight, a factor that most people underestimate, the German car offers a marginal difference of 9% 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. These are the official statistics, 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. Independent research findings rank 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 4.2, while the one under the competitor's bonnet gets 4.7 out of 5.

Hyundai is undoubtly more agile, reaching 100km/h in 1.2 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 208 kilometers per hour, 8km/h less than the other car. When it comes to fuel economy the winner has to be the Korean car, averaging around 7.6 liters of fuel per 100 kilometers (37 mpg), in combined cycle. We can't ignore that 13% 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 much better overall protection, which launches it ahead of the other contender. From there things take a different direction, with Hyundai being considerably quicker, thus putting more smile on driver's face. To make things even better, it consumps less fuel! It's not difficult to say then that if I'd need to make a choice, it would definitely be the Hyundai. In any case that's my personal view, built upon all the data available to me. What should decide here though is the way you feel about the two vehicles, and I hope you'll find my guidelines useful in the process.
