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, 8-valves 115hp unit, while the other one gets its power and torque from a 4-cylinder, 8-valves 120hp 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. Moving further on, let's take a closer look at some additional safety-related facts. 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. On the other hand, 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, all the models observed together. That's the official data, 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. Independent research findings rank Stilo as average reliability-wise, and Astra is more or less at the same level.That apart, owners of different cars powered by the same engine as the Italian car rank it on average as 4.0, while the one under the competitor's bonnet gets 4.5 out of 5.

Opel is a bit more agile, reaching 100km/h in 0.2 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 193 kilometers per hour, 1km/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 (51 mpg), in combined cycle.

Opel 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. the Italian car still consumps less fuel, which needs to be taken into consideration. It's really tough to make a final decision here, but if I'd need to, I'd say Opel. 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.
