Virtual Adviser's™ opinion
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 Opel-engineered powertrain under the hood, a 6-cylinder, 24-valves 230hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 245hp engine designed by Nissan.
SafetyThe 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. Still, apart from the official crash test results there are other things we need to be aware of. 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 considerable difference of 10% more metal.
ReliabilityManufacturers 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, as well as Renault, with the same average rating of 4.2 out of 5. Some independent research have also placed Signum 50% below average, and Vel Satis those same 50% above the first one. That apart, owners of different cars powered by the same engine as the German car rank it on average as 3.0, while the one under the competitor's bonnet gets 4.3 out of 5.
Performance & Fuel economyOpel is a bit more agile, reaching 100km/h in 0.7 seconds less than its competitor. In addition to that it accelerates all the way to 243 kilometers per hour, 8km/h more than the other car. When it comes to fuel economy the winner has to be the German car, averaging around 10.6 liters of fuel per 100 kilometers (27 mpg), in combined cycle. We can't ignore that 8% 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. From there things take a different direction, with Opel being considerably quicker, thus putting more smile on driver's face. 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 Opel. 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.
