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 diesel engine choice they offer. The first one has a FIAT-engineered powertrain under the hood, a 4-cylinder, 16-valves 120hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 150hp engine designed by Volkswagen.

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, 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 potentially life-saving difference of 31% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Škoda does have a slight advantage, all the models observed together. That's the official data, while our visitors describe reliability of Opel with an average rating of 4.2, and models under the Škoda badge with 4.4 out of 5. Some independent research have also placed Insignia as average reliability-wise, and Octavia is more or less at the same level.That apart, owners of different cars powered by the same engine as the German car rank it on average as 2.5, while the one under the competitor's bonnet gets 4.6 out of 5.

Škoda is way more agile, reaching 100km/h in 3.8 seconds less than its competitor. In addition to that it accelerates all the way to 216 kilometers per hour, 26km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 4.1 liters of fuel per 100 kilometers (70 mpg), in combined cycle.

Škoda 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 much better overall protection, which launches it ahead of the other contender. From there things take a different direction, with Škoda 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... It's really tough to make a final decision here, but if I'd need to, I'd say Škoda. 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.
