Well, these are two pretty similar cars we have here! It's only details that could potentially make the difference. Having both cars powered by diesel engines and utilizing the 5-door suv body style within the same 'SUV' segment, the only major difference here really is their wheel drive configuration (front for the Nissan and 4 x 4 in the case of the Renault).

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. That aside, let's consider some other aspects which affect safety. 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 7% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that both brands display similar results in faults and breakdowns, all the models observed together. These are the results of an independent reasearch, while our visitors describe reliability of Nissan with an average rating of 4.3, and models under the Renault badge with 4.1 out of 5. The same official information place X-Trail as average reliability-wise, and Koleos is more or less at the same level.Above it all, drivers of cars with the same engine as these two vehicles rank it on average as 4.5 out of 5.

Nissan is undoubtly more agile, reaching 100km/h in 1.1 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 199 kilometers per hour, 3km/h less than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 5.5 liters of fuel per 100 kilometers (52 mpg), in combined cycle.

Renault 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. From there things take a different direction, with Nissan being considerably quicker, thus putting more smile on driver's face. It does come at a cost though, and that's the fuel consumption... No mistake, whatever you decide here, but I'd still go for the Renault. Nevertheless, let's not forget that people have different preferences and needs, so what really counts is your personal feel.
