Virtual Adviser's™ opinion


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 5-door wagon body style within the same 'Large family car' segment, the only major difference here really is their wheel drive configuration (front for the Opel and 4 x 4 in the case of the Alfa Romeo). The first one has a Opel-engineered powertrain under the hood, a 6-cylinder, 24-valves 230hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 260hp engine designed by Alfa Romeo.


Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the Alfa Romeo 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 large family car segment, which is generally a good thing safety-wise, but that fact doesn't break the tie between the two cars. On the other hand, taking kerb weight as an important factor into account, the Italian car offers a marginal difference of 6% more metal.


Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Opel as a brand displays somewhat better results, at least on all of the models level. That's the official data, while our visitors describe reliability of Opel, as well as Alfa Romeo, with the same average rating of 4.2 out of 5. Independent research findings rank Vectra as average reliability-wise, and 159 is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as the German car rank it on average as 3.0, while the one under the competitor's bonnet gets 5.0 out of 5.

Performance & Fuel economy

Alfa Romeo is a bit more agile, reaching 100km/h in 0.3 seconds less than its competitor. In addition to that it accelerates all the way to 248 kilometers per hour, 3km/h more than the other car. When it comes to fuel economy the winner has to be the German car, averaging around 10.4 liters of fuel per 100 kilometers (27 mpg), in combined cycle. We can't ignore that 7% difference compared to the Italian car.


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 much better overall protection, which launches it ahead of the other contender. It all continues in the same direction, with Alfa Romeo offering somewhat better performance, just enough to call it quicker. 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 Alfa Romeo. 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, among thousands of similar, yet so different vehicles.
