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 250hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 245hp engine designed by Nissan.

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. 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, taking kerb weight as an important factor into account, the French car offers a considerable difference of 10% 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. 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. Some independent research have also placed 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 5.0, while the one under the competitor's bonnet gets 4.3 out of 5.

Opel 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.

Opel 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! No mistake, whatever you decide here, but I'd still go for the Opel. Anyway, that's the most objective conclusion I could've came up with and it's based solely on the information found on this website. Aspects such as design, practicality, brand value and driving experience are there for you to measure them out.
