Well, these are two pretty similar cars we have here! It's only details that could potentially make the difference. Not only that they both belong to the suv segment and utilize the same 5-door suv body style, they are even powered by the same Peugeot-developed diesel engine! There is not much there to point us towards one vehicle or the other. Or is it?

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), 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 suv segment, which is generally a very good thing safety-wise, but it doesn't do much to help us decide between the two. On the other hand, taking kerb weight as an important factor into account, the French car offers a marginal difference of 4% 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. Some independent research have also placed Grandland X as average reliability-wise, and 5008 is more or less at the same level.That apart, owners of different cars powered by the same engine as these two vehicles rank it on average as 4.3 out of 5.

Peugeot is a bit more agile, reaching 100km/h in 0.4 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 188 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 4.3 liters of fuel per 100 kilometers (66 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 French car offers slightly better overall protection and takes the lead. It all continues in the same direction, with Peugeot offering somewhat better performance, just enough to call it quicker. To make things even better, it consumps less fuel! It's not difficult to say then that if I'd need to make a choice, it would definitely be the Peugeot. In any case that's my personal view, built upon all the data available to me. What should decide here though is the way you feel about the two vehicles, and I hope you'll find my guidelines useful in the process. 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™, out of 12.000+ vehicles we currently have in our database.
