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 200hp 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 13% more metal.

Reliability

I don't like generalizing things when it comes to reliability, although it does seem that Opel as a brand displays somewhat better results, at least on all of the models level. 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. Above it all, drivers of cars with the same engine as the Italian car rank it on average as 3.4, while the one under the competitor's bonnet gets 3.0 out of 5.

Performance & Fuel economy

Opel is undoubtly more agile, reaching 100km/h in 2.2 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 229 kilometers per hour, 3km/h less than the other car. When it comes to fuel economy the winner has to be the Italian car, averaging around 8.2 liters of fuel per 100 kilometers (34 mpg), in combined cycle. We can't ignore that 12% difference compared to the German car.


Verdict

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 Italian car offers significantly better overall protection, taking the lead here. From there things take a different direction, with Opel being considerably quicker, thus putting more smile on driver's face. It does come at a cost though, and that's the fuel consumption... It's not difficult to say then that if I'd need to make a choice, it would definitely be the Alfa Romeo. 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. Also, you could use the oportunity to find out which car, everything taken into account, would be the perfect choice for you in the eyes of the virtual adviser, among more than 12.000 different ones in our database.
