Virtual Adviser's™ opinion
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 Opel-engineered powertrain under the hood, a 4-cylinder, 16-valves 140hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 112hp engine designed by Renault.Safety
The first thing to look into here would be the results from European New Car Assessment Programme (Euro NCAP) tests performed on the two cars. Good thing is that both vehicles got tested, 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, taking kerb weight as an important factor into account, the German car offers a marginal difference of 8% more metal.Reliability
Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Renault does have a slight advantage, at least on all of the models level. 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 17% below average, and Megane 19% above the first one. Above it all, drivers of cars with the same engine as the German car rank it on average as 4.5, while the one under the competitor's bonnet gets 3.9 out of 5.Performance & Fuel economy
Opel is a bit more agile, reaching 100km/h in 0.4 seconds less than its competitor. In addition to that it accelerates all the way to 209 kilometers per hour, 14km/h more than the other car. When it comes to fuel economy the winner has to be the French car, averaging around 6.9 liters of fuel per 100 kilometers (41 mpg), in combined cycle. We can't ignore that 12% 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. It all continues in the same direction, with Opel offering somewhat better performance, just enough to call it quicker. It does come at a cost though, and that's the fuel consumption... I believe that, when we take all into account, we have only one winner here - 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.
