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 160hp engine designed by Mazda.

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 Ford 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. On the other hand, if we'd like to consider vehicle mass in this context too, which we definitely should, the American car offers a marginal difference of 2% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Ford does have a slight advantage, when all the models are taken into account. These are the official statistics, while our visitors describe reliability of Opel with an average rating of 4.2, and models under the Ford badge with 4.4 out of 5. Some independent research have also placed Vectra as average reliability-wise, and Mondeo 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 5.0 out of 5.

Opel is undoubtly more agile, reaching 100km/h in 1.2 seconds less than its competitor. In addition to that it accelerates all the way to 210 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 7.8 liters of fuel per 100 kilometers (36 mpg), in combined cycle. We can't ignore that 19% difference compared to the American car.

Ford is apparently more reliable, not too much, but just enough. 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 American car offers much better overall protection, which launches it ahead of the other contender. From there things take a different direction, with Opel outracing its opponent in any situation possible, making it better choice for boy racers. To make things even better, it consumps less fuel! No mistake, whatever you decide here, but I'd still go for the Opel. Nevertheless, let's not forget that people have different preferences and needs, so what really counts is your personal feel.
