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 small family car segment and utilize the same 3-door hatchback 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 4-cylinder, 16-valves 90hp unit, while the other one gets its power and torque from a 4-cylinder, 8-valves 100hp one.

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 Opel being a slightly better choice apparently. Still, apart from the official crash test results there are other things we need to be aware of. Both vehicles belong to the small family car segment, which is generally classifying them somewhere in the middle safety-wise, but it doesn't do much to help us decide between the two. Furthermore, if we'd like to consider vehicle mass in this context too, which we definitely should, the German car offers a marginal difference of 1% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning that FIAT does have a slight advantage, all the models observed together. These are the official statistics, while our visitors describe reliability of Opel with an average rating of 4.2, and models under the FIAT badge with 4.3 out of 5. Independent research findings rank Astra as average reliability-wise, and Stilo is more or less at the same level.That apart, owners of different cars powered by the same engine as the German car rank it on average as 4.1, while the one under the competitor's bonnet gets 4.4 out of 5.

There's not enough data for me to elaborate on the subject, I'm affraid.

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 my opinion, everything taken into account, the German car offers much better overall protection, which launches it ahead of the other contender. When it comes to performance, both vehicles provide similar experience, so I wouldn't point any of them out. Fuel consumption is more or less the same. I believe that, when we take all into account, we have only one winner here - the 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. 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.
