Virtual Adviser's™ opinion

Overview

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, 8-valves 120hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 173hp engine designed by Renault.

Safety

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the Renault being a slightly better choice apparently. That aside, let's consider some other aspects which affect safety. 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, if we'd like to consider vehicle mass in this context too, which we definitely should, the French car offers a marginal difference of 8% more metal.

Reliability

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. That's the official data, while our visitors describe reliability of Opel, as well as Renault, with the same average rating of 4.2 out of 5. Independent research findings rank Signum as average reliability-wise, and Vel Satis 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 4.5, while the one under the competitor's bonnet gets 4.8 out of 5.

Performance & Fuel economy

Renault is undoubtly more agile, reaching 100km/h in 2.5 seconds less than its competitor. In addition to that it accelerates all the way to 211 kilometers per hour, 18km/h more than the other car. When it comes to fuel economy the winner has to be the German car, averaging around 5.9 liters of fuel per 100 kilometers (48 mpg), in combined cycle. We can't ignore that 24% difference compared to the French car.


Verdict

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 being considerably quicker, thus putting more smile on driver's face. It does come at a cost though, and that's the fuel consumption... No mistake, whatever you decide here, but I'd still go for 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. 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, out of 12.000+ vehicles we currently have in our database.
