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 Nissan-engineered powertrain under the hood, a 4-cylinder, 16-valves 132hp unit, while the other one gets its power and torque from a 3-cylinder, 12-valves 105hp engine designed by General Motors.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the same number of safety stars gained in the process. That aside, let's consider some other aspects which affect safety. Both vehicles belong to the small family car segment, which is generally classifying them somewhere in the middle safety-wise, still it doesn't help us solve our dilemma, does it? Furthermore, taking kerb weight as an important factor into account, the French car offers a marginal difference of 7% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Renault does have a slight advantage, when all the models are taken into account. These are the results of an independent reasearch, 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.That apart, owners of different cars powered by the same engine as the French car rank it on average as 5.0, while the one under the competitor's bonnet gets 3.0 out of 5.

Renault is a bit more agile, reaching 100km/h in 0.7 seconds less than its competitor. In addition to that it accelerates all the way to 198 kilometers per hour, 3km/h more than the other car. When it comes to fuel economy the winner has to be the German car, averaging around 4.3 liters of fuel per 100 kilometers (66 mpg), in combined cycle. We can't ignore that 23% difference compared to the French car.

Renault 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 French car offers slightly better overall protection and takes the lead. It all continues in the same direction, with Renault offering somewhat better performance, just enough to call it quicker. It does come at a cost though, and that's the fuel consumption... At the end, as much as I'd like to give you a winner here, it's simply a pure tie if you ask me. 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.
