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 hatchback 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 125hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 175hp engine designed by Opel.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), 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, when it comes to weight, a factor that most people underestimate, the German car offers a considerable difference of 13% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears 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 Ford with an average rating of 4.4, and models under the Opel badge with 4.2 out of 5. The same official information place Mondeo as average reliability-wise, and Signum is more or less at the same level.That apart, owners of different cars powered by the same engine as the American car rank it on average as 4.6, while the one under the competitor's bonnet gets 3.9 out of 5.

Opel is undoubtly more agile, reaching 100km/h in 1.5 seconds less than its competitor. In addition to that it accelerates all the way to 220 kilometers per hour, 15km/h more than the other car. When it comes to fuel economy the winner has to be the American car, averaging around 7.8 liters of fuel per 100 kilometers (36 mpg), in combined cycle. We can't ignore that 14% difference compared to the German car.

Ford 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 significantly better overall protection, taking the lead here. It all continues in the same direction, with Opel outracing its opponent in any situation possible, making it better choice for boy racers. 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. Also, you could use the oportunity to find out which car, everything taken into account, would be the perfect choice for you in the eyes of the virtual adviser™, among thousands of similar, yet so different vehicles.
