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 General Motors-engineered powertrain under the hood, a 4-cylinder, 16-valves 101hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 115hp engine designed by Nissan.

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. Moving further on, let's take a closer look at some additional safety-related facts. 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. On the other hand, when it comes to weight, a factor that most people underestimate, the French car offers a marginal difference of 7% 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, all the models observed together. These are the official statistics, while our visitors describe reliability of Opel, as well as Renault, with the same average rating of 4.2 out of 5. Independent research findings rank Astra as average reliability-wise, and Megane 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 5.0, while the one under the competitor's bonnet gets 3.0 out of 5.

Renault is undoubtly more agile, reaching 100km/h in 2.8 seconds less than its competitor. In addition to that it accelerates all the way to 190 kilometers per hour, 5km/h more than the other car. When it comes to fuel economy an obvious choice would be the German car, averaging around -0.2 liters of fuel per 100 kilometers (-1413 mpg), in combined cycle. That's 1% 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... No mistake, whatever you decide here, but I'd still go for the Opel. 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.
