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 5-door hatchback body style and the front wheel drive system, it all comes up to the specific petrol engine choice they offer. Both the engines are Opel-engineered . The first one has a 4-cylinder, 16-valves 170hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 105hp 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. 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, but that fact doesn't break the tie between the two cars. 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 5% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that FIAT does have a slight advantage, at least on all of the models level. These are the official statistics, while our visitors describe reliability of Opel, as well as FIAT, with the same average rating of 4.2 out of 5. The same official information place 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 3.0, while the one under the competitor's bonnet gets 3.9 out of 5.

Opel is way more agile, reaching 100km/h in 3.4 seconds less than its competitor. In addition to that it accelerates all the way to 217 kilometers per hour, 34km/h more than the other car. When it comes to fuel economy an obvious choice would be the Italian car, averaging around 7 liters of fuel per 100 kilometers (40 mpg), in combined cycle. That's 30% difference compared to the German 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 my opinion, everything taken into account, the German car offers much better overall protection, which launches it ahead of the other contender. 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 FIAT. Anyway, that's the most objective conclusion I could've came up with and it's based solely on the information found on this website. Aspects such as design, practicality, brand value and driving experience are there for you to measure them out.
