Virtual Adviser's™ opinion

Overview

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 (front for the Alfa Romeo and rear in the case of the Opel). The first one has a Alfa Romeo-engineered powertrain under the hood, a 4-cylinder, 16-valves 185hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 264hp engine designed by Opel.

Safety

Unfortunatelly, neither of the two vehicles was submitted to the European New Car Assessment Programme (Euro NCAP) testing. This makes it virtually impossible for me to pick one over the other and I'm generally against buying such cars as the safety should really always come first. That aside, let's consider some other aspects which affect safety. 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. Furthermore, taking kerb weight as an important factor into account, the Italian car offers a considerable difference of 15% more metal.

Reliability

Reliability is not the best thing to consider on the make level, but it is worth mentioning that Opel as a brand displays somewhat better results, all the models observed together. These are the official statistics, while our visitors describe reliability of Alfa Romeo, as well as Opel, with the same average rating of 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. That apart, owners of different cars powered by the same engine as the Italian car rank it on average as 4.5, while the one under the competitor's bonnet gets 3.0 out of 5.

Performance & Fuel economy

Opel is way more agile, reaching 100km/h in 3.1 seconds less than its competitor. In addition to that it accelerates all the way to 229 kilometers per hour, 7km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 9.3 liters of fuel per 100 kilometers (30 mpg), in combined cycle.


Verdict

Alfa Romeo 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 Italian car offers significantly better overall protection, taking the lead here. From there things take a different direction, with Opel outracing its opponent in any situation possible, making it better choice for boy racers. 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. I suggest you spend two more minutes in order to find out which car, based on your needs and budget, would be picked by the virtual adviser, out of 12.000+ vehicles we currently have in our database.
