Well, these are two pretty similar cars we have here! It's only details that could potentially make the difference. Considering they both belong to the large family car segment and utilize the same 5-door wagon body style and the front wheel drive system, it all comes up to the specific petrol engine choice they offer. The first one has a Renault-engineered powertrain under the hood, a 4-cylinder, 16-valves 136hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 136hp engine designed by Opel.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the same number of safety stars gained in the process. Still, apart from the official crash test results there are other things we need to be aware of. Both vehicles belong to the large family car segment, which is generally a good thing safety-wise, but it doesn't do much to help us decide between the two. Furthermore, taking kerb weight as an important factor into account, the French car offers a marginal difference of 3% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning 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 Renault, as well as Opel, with the same average rating of 4.2 out of 5. Independent research findings rank Laguna as average reliability-wise, and Vectra is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as the French car rank it on average as 3.6, while the one under the competitor's bonnet gets 5.0 out of 5.

Renault is a bit more agile, reaching 100km/h in 0.6 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 200 kilometers per hour, 7km/h less than the other car. When it comes to fuel economy the winner has to be the French car, averaging around 7.9 liters of fuel per 100 kilometers (36 mpg), in combined cycle. We can't ignore that 10% difference compared to the German 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 offers slightly better overall protection and takes the lead. When it comes to performance, both vehicles provide similar experience, so I wouldn't point any of them out. the French car , on the other hand, consumps significantly less fuel, and that's a big plus. All together, there's not much more to say, in this case I wouldn't even consider anything but Renault. 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.
