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 3-door hatchback 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 Opel-engineered powertrain under the hood, a 4-cylinder, 16-valves 90hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 98hp engine designed by Renault.

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, still it doesn't help us solve our dilemma, does it? On the other hand, when it comes to weight, a factor that most people underestimate, the French car offers a marginal difference of 1% 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. These are the official statistics, while our visitors describe reliability of Opel with an average rating of 4.2, and models under the Renault badge with 4.1 out of 5. The same official information place Astra as average reliability-wise, and Megane is more or less at the same level.Above it all, drivers of cars with the same engine as the German car rank it on average as 4.1, while the one under the competitor's bonnet gets 3.8 out of 5.

Renault is undoubtly more agile, reaching 100km/h in 1.1 seconds less than its competitor. In addition to that it accelerates all the way to 183 kilometers per hour, 3km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 6.5 liters of fuel per 100 kilometers (43 mpg), in combined cycle.

Renault 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 being considerably quicker, thus putting more smile on driver's face. 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 Renault. 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.
