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 wagon body style and the front wheel drive system, it all comes up to the specific diesel engine choice they offer. Both the engines are FIAT-engineered . The first one has a 5-cylinder, 20-valves 200hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 195hp one.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), 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, but that fact doesn't break the tie between the two cars.

I don't like generalizing things when it comes to reliability, although it does seem that FIAT does have a slight advantage, all the models observed together. These are the results of an independent reasearch, while our visitors describe reliability of FIAT with an average rating of 4.3, and models under the Opel badge with 4.2 out of 5. The same official information place Croma 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 Italian car rank it on average as 4.7, while the one under the competitor's bonnet gets 5.0 out of 5.

FIAT is a bit more agile, reaching 100km/h in 0.4 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 216 kilometers per hour, 9km/h less than the other car. When it comes to fuel economy an obvious choice would be the German car, averaging around 5.1 liters of fuel per 100 kilometers (55 mpg), in combined cycle. That's 41% difference compared to the Italian car!

FIAT 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 this case though, it seems that both cars show similar levels of passenger protection all together, so that won't break a tie. When it comes to performance, both vehicles provide similar experience, so I wouldn't point any of them out. the German car is in a different dimension economy-wise, and many people will find that crucial. All together, there's not much more to say, in this case I wouldn't even consider anything but 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.
