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 large family car segment and utilize the same 5-door wagon body style and the front wheel drive system, it all comes up to the specific petrol engine choice they offer. Both the engines are Opel-engineered . The first one has a 4-cylinder, 16-valves 175hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 220hp 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 same number of safety stars gained in the process. Still, apart from the official crash test results there are other things we need to be aware of. 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, when it comes to weight, a factor that most people underestimate, the German car offers a considerable difference of 13% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that both brands display similar results in faults and breakdowns, at least on all of the models level. These are the official statistics, while our visitors describe reliability of SAAB with an average rating of 4.1, and models under the Opel badge with 4.2 out of 5. Some independent research have also placed 9-3 as average reliability-wise, and Insignia is more or less at the same level.That apart, owners of different cars powered by the same engine as the Swedish car rank it on average as 4.0, while the one under the competitor's bonnet gets 4.7 out of 5.

Opel is a bit more agile, reaching 100km/h in 0.9 seconds less than its competitor. In addition to that it accelerates all the way to 236 kilometers per hour, 21km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 8.4 liters of fuel per 100 kilometers (34 mpg), in combined cycle.

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 German car offers significantly better overall protection, taking the lead here. It all continues in the same direction, with Opel 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 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.
