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 hatchback body style and the front wheel drive system, it all comes up to the specific diesel engine choice they offer. The first one has a Peugeot-engineered powertrain under the hood, a 4-cylinder, 16-valves 130hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 136hp engine designed by General Motors.

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, still it doesn't help us solve our dilemma, does it? On the other hand, taking kerb weight as an important factor into account, the German car offers a marginal difference of 1% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Peugeot does have a slight advantage, when all the models are taken into account. These are the results of an independent reasearch, while our visitors describe reliability of Peugeot with an average rating of 4.3, and models under the Opel badge with 4.2 out of 5. The same official information place 508 as average reliability-wise, and Insignia is more or less at the same level.Above it all, drivers of cars with the same engine as the French car rank it on average as 4.0, while the one under the competitor's bonnet gets 3.9 out of 5.

Peugeot is a bit more agile, reaching 100km/h in 0.8 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 210 kilometers per hour, 1km/h less than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 4.1 liters of fuel per 100 kilometers (70 mpg), in combined cycle.

Peugeot 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 slightly better overall protection and takes the lead. When it comes to performance, both vehicles provide similar experience, so I wouldn't point any of them out. the French car still consumps less fuel, which needs to be taken into consideration. It's really tough to make a final decision here, but if I'd need to, I'd say 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.
