Well, these are two pretty similar cars we have here! It's only details that could potentially make the difference. Not only that they both belong to the small family car segment and utilize the same 5-door hatchback body style, they are even powered by the same FIAT-developed diesel engine! There is not much there to point us towards one vehicle or the other. Or is it?

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the Opel being a slightly better choice apparently. That aside, let's consider some other aspects which affect safety. Both vehicles belong to the small family car segment, which is generally classifying them somewhere in the middle safety-wise, still it doesn't help us solve our dilemma, does it? On the other hand, when it comes to weight, a factor that most people underestimate, the Italian car offers a marginal difference of 1% more metal.

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 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. The same official information place Astra as average reliability-wise, and Stilo is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as these two vehicles rank it on average as 4.5 out of 5.

Opel 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 191 kilometers per hour, 3km/h less than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 5.6 liters of fuel per 100 kilometers (50 mpg), in combined cycle.

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 slightly better overall protection and takes the lead. It all continues in the same direction, with Opel offering somewhat better performance, just enough to call it quicker. It does come at a cost though, and that's the fuel consumption... At the end, as much as I'd like to give you a winner here, it's simply a pure tie if you ask me. Nevertheless, let's not forget that people have different preferences and needs, so what really counts is your personal feel. I'm only here to help.
