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 city car segment and utilize the same 5-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 70hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 75hp 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 displaying significantly better structural stability. Still, apart from the official crash test results there are other things we need to be aware of. Both vehicles belong to the city car segment, which is generally not a very good thing safety-wise, still it doesn't help us solve our dilemma, does it? 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 considerable difference of 25% 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, when all the models are taken into account. 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 Panda as average reliability-wise, and Corsa 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 4.3, while the one under the competitor's bonnet gets 4.0 out of 5.

FIAT is undoubtly more agile, reaching 100km/h in 1.5 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 160 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 4.5 liters of fuel per 100 kilometers (63 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 beats the other contender by far, making it the best choice without even considering other things. From there things take a different direction, with FIAT being considerably quicker, thus putting more smile on driver's face. To make things even better, it consumps less fuel! No mistake, whatever you decide here, but I'd still go for the Opel. 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.
