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 Renault-engineered powertrain under the hood, a 4-cylinder, 16-valves 130hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 100hp engine designed by Opel.

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. Still, apart from the official crash test results there are other things we need to be aware of. 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. On the other hand, if we'd like to consider vehicle mass in this context too, which we definitely should, the German car offers a marginal difference of 3% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning that Renault does have a slight advantage, at least on all of the models level. These are the official statistics, while our visitors describe reliability of Renault with an average rating of 4.1, and models under the Opel badge with 4.2 out of 5. Some independent research have also placed Megane as average reliability-wise, and Astra is more or less at the same level.Above it all, drivers of cars with the same engine as the French car rank it on average as 3.3, while the one under the competitor's bonnet gets 4.5 out of 5.

Renault is way more agile, reaching 100km/h in 4.5 seconds less than its competitor. In addition to that it accelerates all the way to 200 kilometers per hour, 25km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 6 liters of fuel per 100 kilometers (47 mpg), in combined cycle.

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 German car offers much better overall protection, which launches it ahead of the other contender. From there things take a different direction, with Renault 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.
