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 98hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 65hp engine designed by Opel.

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. 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, but that fact doesn't break the tie between the two cars. Furthermore, when it comes to weight, a factor that most people underestimate, the French car offers a marginal difference of 4% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Renault does have a slight advantage, when all the models are taken into account. That's the official data, 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. The same official information place Megane as average reliability-wise, and Astra is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as the French car rank it on average as 3.8, while the one under the competitor's bonnet gets 4.8 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 182 kilometers per hour, 22km/h more than the other car. When it comes to fuel economy the winner has to be the German car, averaging around 6.2 liters of fuel per 100 kilometers (46 mpg), in combined cycle. We can't ignore that 13% difference compared to the French car.

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 French car offers slightly better overall protection and takes the lead. It all continues in the same 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... 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. 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™, out of 12.000+ vehicles we currently have in our database.
