Two significantly similar cars, no doubt about that. Still, each one has something different to offer. Having both cars powered by petrol engines and utilizing the 2-door cabriolet body style within the same 'Sports car' segment, the only major difference here really is their wheel drive configuration (rear for the FIAT and front in the case of the Opel). The first one has a FIAT-engineered powertrain under the hood, a 4-cylinder, 16-valves 170hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 140hp engine designed by Opel.

The fact that the FIAT got tested by the European New Car Assessment Programme (Euro NCAP), while the other contender didn't, offers a slight advantage, as the 4-star rating is better than none. Still, apart from the official crash test results there are other things we need to be aware of. Both vehicles belong to the sports 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, when it comes to weight, a factor that most people underestimate, the German car offers a self-explainatory difference of 51% 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, at least on all of the models level. 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. Unfortunatelly, I don't have enough insight that would allow me to comment in more details on the specific models level. We should definitely mention that owners of cars with the same powertrain as the Italian car rank it on average as 4.8, while the one under the competitor's bonnet gets 4.0 out of 5.

FIAT is way more agile, reaching 100km/h in 4.1 seconds less than its competitor. In addition to that it accelerates all the way to 232 kilometers per hour, 25km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 6.4 liters of fuel per 100 kilometers (44 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 this case though, it seems that both cars show similar levels of passenger protection all together, so that won't break a tie. But one thing that actually could is the performance, with FIAT 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. In case you have two minutes to spare I invite you to define your needs, desires and budget and see which car would be chosen by the virtual adviser™, among thousands of similar, yet so different vehicles.
