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 4-door sedan body style within the same 'Large family car' segment, the only major difference here really is their wheel drive configuration (4 x 4 for the Opel and front in the case of the Peugeot). The first one has a Opel-engineered powertrain under the hood, a 4-cylinder, 16-valves 250hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 165hp engine designed by Peugeot.

The first thing to look into here would be the results from European New Car Assessment Programme (Euro NCAP) tests performed on the two cars. Good thing is that both vehicles got tested, with the same number of safety stars gained in the process. 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. Furthermore, when it comes to weight, a factor that most people underestimate, the German car offers a considerable difference of 19% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Peugeot does have a slight advantage, when all the models are taken into account. These are the official statistics, while our visitors describe reliability of Opel with an average rating of 4.2, and models under the Peugeot badge with 4.3 out of 5. Independent research findings rank Insignia as average reliability-wise, and 508 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 1.0, while the one under the competitor's bonnet gets 4.8 out of 5.

Opel is undoubtly more agile, reaching 100km/h in 1.1 seconds less than its competitor. In addition to that it accelerates all the way to 250 kilometers per hour, 40km/h more than the other car. When it comes to fuel economy an obvious choice would be the French car, averaging around 5.6 liters of fuel per 100 kilometers (50 mpg), in combined cycle. That's 39% difference compared to the German car!

Peugeot is apparently more reliable, not too much, but just enough. 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 being considerably quicker, thus putting more smile on driver's face. It does come at a cost though, and that's the fuel consumption... All together, there's not much more to say, in this case I wouldn't even consider anything but Peugeot. 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. 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 thousands of similar, yet so different vehicles.
