Overview

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 diesel engine choice they offer. The first one has a Nissan-engineered powertrain under the hood, a 4-cylinder, 16-valves 126hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 125hp engine designed by Opel.

Safety

The 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 same number of safety stars gained in the process. Moving further on, let's take a closer look at some additional safety-related facts. Both vehicles belong to the large family car segment, which is generally a good thing safety-wise, still it doesn't help us solve our dilemma, does it? On the other hand, taking kerb weight as an important factor into account, the German car offers a marginal difference of 7% more metal.

Reliability

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Nissan does have a slight advantage, all the models observed together. That's the official data, while our visitors describe reliability of Nissan with an average rating of 4.3, and models under the Opel badge with 4.2 out of 5. Independent research findings rank Primera 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 Japanese car rank it on average as 3.0, while the one under the competitor's bonnet gets 3.9 out of 5.

Performance & Fuel economy

Nissan is undoubtly more agile, reaching 100km/h in 1.3 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 195 kilometers per hour, exactly the same as the other car does. When it comes to fuel economy things look pretty much the same for both cars, averaging around 6.1 liters of fuel per 100 kilometers (47 mpg), in combined cycle.

Verdict

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 German car offers slightly better overall protection and takes the lead. From there things take a different direction, with Nissan being considerably quicker, thus putting more smile on driver's face. It does come at a cost though, and that's the fuel consumption... It's really tough to make a final decision here, but if I'd need to, I'd say 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.
