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 Mazda-engineered powertrain under the hood, a 4-cylinder, 16-valves 160hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 155hp 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 Ford being a slightly better choice apparently. 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, but it doesn't do much to help us decide between the two. Furthermore, 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, all the models observed together. That's the official data, while our visitors describe reliability of Ford with an average rating of 4.4, and models under the Opel badge with 4.2 out of 5. Independent research findings rank Mondeo 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 American car rank it on average as 5.0, while the one under the competitor's bonnet gets 3.0 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 being considerably quicker, thus putting more smile on driver's face. To make things even better, it consumps less fuel! It's really tough to make a final decision here, but if I'd need to, I'd say Opel. In any case that's my personal view, built upon all the data available to me. What should decide here though is the way you feel about the two vehicles, and I hope you'll find my guidelines useful in the process. In case you have two minutes to spare I invite you to define your needs, desires and budget and see which car would be chosen by the virtual adviser™, among thousands of similar, yet so different vehicles.
