Two significantly similar cars, no doubt about that. Still, each one has something different to offer. Having both cars powered by petrol engines and utilizing the 5-door wagon body style within the same 'Large family car' segment, the only major difference here really is their wheel drive configuration (4 x 4 for the Volkswagen and front in the case of the Opel). The first one has a Volkswagen-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 250hp engine designed by Opel.

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 Volkswagen being a slightly better choice apparently. That aside, let's consider some other aspects which affect safety. Both vehicles belong to the large family car segment, which is generally a good thing safety-wise, but that fact doesn't break the tie between the two cars. Furthermore, when it comes to weight, a factor that most people underestimate, Passat offers a considerable difference of 16% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that both brands display similar results in faults and breakdowns, when all the models are taken into account. These are the official statistics, while our visitors describe reliability of Volkswagen, as well as Opel, with the same average rating of 4.2 out of 5. Some independent research have also placed Passat as average reliability-wise, and Vectra is more or less at the same level.Above it all, drivers of cars with the same engine as Passat rank it on average as 4.3, while the one under the competitor's bonnet gets 5.0 out of 5.

Volkswagen is a bit more agile, reaching 100km/h in 0.3 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 243 kilometers per hour, 2km/h less than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 10.2 liters of fuel per 100 kilometers (28 mpg), in combined cycle.

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, Passat beats the other contender by far, making it the best choice without even considering other things. It all continues in the same direction, with Volkswagen offering somewhat better performance, just enough to call it quicker. To make things even better, it consumps less fuel! All together, there's not much more to say, in this case I wouldn't even consider anything but Volkswagen. 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.
