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 2-door cabriolet 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 163hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 170hp engine designed by Opel.

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, but that fact doesn't break the tie between the two cars. 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 8% 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 results of an independent reasearch, while our visitors describe reliability of Renault, as well as Opel, with the same average rating of 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.Above it all, drivers of cars with the same engine as the French car rank it on average as 4.3, while the one under the competitor's bonnet gets 3.0 out of 5.

Renault is a bit more agile, reaching 100km/h in 0.8 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 220 kilometers per hour, 4km/h less than the other car. When it comes to fuel economy the winner has to be the French car, averaging around 7.9 liters of fuel per 100 kilometers (36 mpg), in combined cycle. We can't ignore that 16% difference compared to the German car.

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 German car offers slightly better overall protection and takes the lead. When it comes to performance, both vehicles provide similar experience, so I wouldn't point any of them out. the French car , on the other hand, consumps significantly less fuel, and that's a big plus. It's not difficult to say then that if I'd need to make a choice, it would definitely be the Renault. In any case that's my personal view, built upon all the data available to me. What should decide here though is the way you feel about the two vehicles, and I hope you'll find my guidelines useful in the process.
