Virtual Adviser's™ opinion
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 Opel-engineered powertrain under the hood, a 4-cylinder, 16-valves 155hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 140hp engine designed by Nissan.
SafetyBoth 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 German car offers a marginal difference of 6% more metal.
ReliabilityI don't like generalizing things when it comes to reliability, although it does seem that Nissan does have a slight advantage, at least on all of the models level. These are the results of an independent reasearch, while our visitors describe reliability of Opel with an average rating of 4.2, and models under the Nissan badge with 4.3 out of 5. Independent research findings rank Vectra as average reliability-wise, and Primera 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 3.0, while the one under the competitor's bonnet gets 4.2 out of 5.
Performance & Fuel economyNissan is a bit more agile, reaching 100km/h in 0.2 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 200 kilometers per hour, 12km/h less than the other car. When it comes to fuel economy the winner has to be the German car, averaging around 8.1 liters of fuel per 100 kilometers (35 mpg), in combined cycle. We can't ignore that 12% difference compared to the Japanese car.
Verdict
Nissan 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 German car offers slightly better overall protection and takes the lead. From there things take a different direction, with Nissan offering somewhat better performance, just enough to call it quicker. 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 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.
