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 5-door wagon 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.

The first thing to look into here would be the results from European New Car Assessment Programme (Euro NCAP) tests performed on the two cars. Good thing is that both vehicles got tested, 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? Furthermore, when it comes to weight, a factor that most people underestimate, the German car offers a considerable difference of 18% 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. These are the results of an independent reasearch, 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 3.6 out of 5.

Opel is undoubtly more agile, reaching 100km/h in 2 seconds less than its competitor. In addition to that it accelerates all the way to 270 kilometers per hour, 35km/h more than the other car. When it comes to fuel economy an obvious choice would be the American car, averaging around 7.5 liters of fuel per 100 kilometers (38 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 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. 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.
