Two significantly similar cars, no doubt about that. Still, each one has something different to offer. Having both cars powered by diesel engines and utilizing the 4-door sedan 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 Ford and front in the case of the Opel). The first one has a Peugeot-engineered powertrain under the hood, a 4-cylinder, 16-valves 150hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 140hp engine designed by FIAT.

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 same number of safety stars gained in the process. Still, apart from the official crash test results there are other things we need to be aware of. 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, taking kerb weight as an important factor into account, the American car offers a marginal difference of 4% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Ford does have a slight advantage, at least on all of the models level. 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. Some independent research have also placed Mondeo as average reliability-wise, and Insignia 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 4.6, while the one under the competitor's bonnet gets 4.5 out of 5.

Ford is a bit more agile, reaching 100km/h in 0.2 seconds less than its competitor. In addition to that it accelerates all the way to 215 kilometers per hour, 10km/h more than the other car. When it comes to fuel economy the winner has to be the German car, averaging around 3.7 liters of fuel per 100 kilometers (76 mpg), in combined cycle. We can't ignore that 30% difference compared to the American 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 American car offers slightly better overall protection and takes the lead. It all continues in the same direction, with Ford offering somewhat better performance, just enough to call it quicker. 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. Nevertheless, let's not forget that people have different preferences and needs, so what really counts is your personal feel. I'm only here to help. 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.
