Two significantly similar cars, no doubt about that. Still, each one has something different to offer. 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 Subaru). The first one has a Renault-engineered powertrain under the hood, a 4-cylinder, 16-valves 178hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 150hp engine designed by Subaru.

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 that fact doesn't break the tie between the two cars.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Nissan does have a slight advantage, at least on all of the models level. That's the official data, while our visitors describe reliability of Nissan with an average rating of 4.3, and models under the Subaru badge with 4.2 out of 5. Some independent research have also placed X-Trail as average reliability-wise, and Outback is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as X-Trail rank it on average as 4.5, while the one under the competitor's bonnet gets 4.7 out of 5.

Nissan 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 199 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 5.6 liters of fuel per 100 kilometers (50 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 this case though, it seems that both cars show similar levels of passenger protection all together, so that won't break a tie. But one thing that actually could is the performance, with Nissan offering somewhat better performance, just enough to call it quicker. Fuel consumption is more or less the same. It's really tough to make a final decision here, but if I'd need to, I'd say Nissan. 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.
