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 diesel engine choice they offer. The first one has a Ford-engineered powertrain under the hood, a 4-cylinder, 16-valves 120hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 110hp engine designed by General Motors.

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. 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 that fact doesn't break the tie between the two cars. Furthermore, taking kerb weight as an important factor into account, the American car offers a marginal difference of 4% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning 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. Independent research findings rank Mondeo as average reliability-wise, and Insignia 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 4.1, while the one under the competitor's bonnet gets 3.6 out of 5.

Ford is a bit more agile, reaching 100km/h in 0.1 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 192 kilometers per hour, 13km/h less than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 4 liters of fuel per 100 kilometers (71 mpg), in combined cycle.

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. Fuel consumption is more or less the same. 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. 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.
