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 Opel being a large family car and the Renault representing luxury car vehicle class. The first one has a FIAT-engineered powertrain under the hood, a 4-cylinder, 16-valves 150hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 173hp engine designed by Renault.

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 Renault being a slightly better choice apparently. Moving further on, let's take a closer look at some additional safety-related facts. The second 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, when it comes to weight, a factor that most people underestimate, the French car offers a marginal difference of 7% 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, as well as Renault, with the same average rating of 4.2 out of 5. The same official information place Signum as average reliability-wise, and Vel Satis is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as the German car rank it on average as 4.2, while the one under the competitor's bonnet gets 4.8 out of 5.

Renault is undoubtly more agile, reaching 100km/h in 1 seconds less than its competitor. In addition to that it accelerates all the way to 211 kilometers per hour, 2km/h more than the other car. When it comes to fuel economy the winner has to be the German car, averaging around 6 liters of fuel per 100 kilometers (47 mpg), in combined cycle. We can't ignore that 22% difference compared to the French 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 French car beats the other contender by far, making it the best choice without even considering other things. 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... I believe that, when we take all into account, we have only one winner here - the Renault. Nevertheless, let's not forget that people have different preferences and needs, so what really counts is your personal feel. I'm only here to help. 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.
