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 Renault-developed diesel engine! There is not much there to point us towards one vehicle or the other. Or is it?

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 Renault 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 suv segment, which is generally a very 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 Japanese car offers a marginal difference of 1% 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, all the models observed together. That's the official data, while our visitors describe reliability of Renault with an average rating of 4.2, and models under the Nissan badge with 4.3 out of 5. Independent research findings rank Koleos as average reliability-wise, and X-Trail 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 4.8 out of 5.

Renault is a bit more agile, reaching 100km/h in 0.1 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 191 kilometers per hour, 9km/h less than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 7.5 liters of fuel per 100 kilometers (38 mpg), in combined cycle.

Nissan 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. When it comes to performance, both vehicles provide similar experience, so I wouldn't point any of them out. the Japanese 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 Nissan. Anyway, that's the most objective conclusion I could've came up with and it's based solely on the information found on this website. Aspects such as design, practicality, brand value and driving experience are there for you to measure them out. In case you have two minutes to spare I invite you to define your needs, desires and budget and see which car would be chosen by the virtual adviser™, among thousands of similar, yet so different vehicles.
