We are here considering two somewhat similar cars, but we can't deny some of the obvious differences. For a start, they are not even classified under the same segment, with the Renault being a luxury car and the Opel representing large family car vehicle class. 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 175hp 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 Renault being a slightly better choice apparently. That aside, let's consider some other aspects which affect safety. The first vehicle is a luxury car and that gives it a marginal advantage over the large family car competitor, at least that's what statistics show. Furthermore, taking kerb weight as an important factor into account, the French car offers a marginal difference of 9% more metal.

I don't like generalizing things when it comes to reliability, although it does seem 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 with an average rating of 4.1, and models under the Opel badge with 4.2 out of 5. Unfortunatelly, I don't have enough insight that would allow me to comment in more details on the specific models level. We should definitely mention that owners of cars with the same powertrain as the French car rank it on average as 4.4, while the one under the competitor's bonnet gets 4.0 out of 5.

Opel is a bit more agile, reaching 100km/h in 0.2 seconds less than its competitor. In addition to that it accelerates all the way to 220 kilometers per hour, 10km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 9.3 liters of fuel per 100 kilometers (30 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 beats the other contender by far, making it the best choice without even considering other things. From there things take a different direction, with Opel offering somewhat better performance, just enough to call it quicker. To make things even better, it consumps less fuel! It's really tough to make a final decision here, but if I'd need to, I'd say 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. I suggest you spend two more minutes in order to find out which car, based on your needs and budget, would be picked by the virtual adviser™, among thousands of similar, yet so different vehicles.
