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 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 Opel and front in the case of the Ford). The first one has a Opel-engineered powertrain under the hood, a 6-cylinder, 24-valves 325hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 240hp 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 same number of safety stars gained in the process. 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, still it doesn't help us solve our dilemma, does it? Furthermore, when it comes to weight, a factor that most people underestimate, the German car offers a considerable difference of 12% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Ford does have a slight advantage, at least on all of the models level. 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. Independent research findings rank Insignia 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 5.0, while the one under the competitor's bonnet gets 4.3 out of 5.

Opel is undoubtly more agile, reaching 100km/h in 1.9 seconds less than its competitor. In addition to that it accelerates all the way to 270 kilometers per hour, 30km/h more than the other car. When it comes to fuel economy an obvious choice would be the American car, averaging around 7.3 liters of fuel per 100 kilometers (39 mpg), in combined cycle. That's 45% difference compared to the German car!

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, the German car offers significantly better overall protection, taking the lead here. It all continues in the same direction, with Opel being considerably quicker, thus putting more smile on driver's face. It does come at a cost though, and that's the fuel consumption... No mistake, whatever you decide here, but I'd still go for the Ford. 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.
