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 (4 x 4 for the Nissan and front in the case of the Mercedes Benz). Both the engines are Renault-engineered . The first one has a 4-cylinder, 16-valves 129hp unit, while the other one gets its power and torque from a 4-cylinder, 8-valves 110hp one.

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 suv segment, which is generally a very good thing safety-wise, but it doesn't do much to help us decide between the two. Furthermore, when it comes to weight, a factor that most people underestimate, the Japanese car offers a considerable difference of 11% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning that Nissan as a brand displays somewhat better results, when all the models are taken into account. That's the official data, while our visitors describe reliability of Nissan with an average rating of 4.3, and models under the Mercedes Benz badge with 4.4 out of 5. Independent research findings rank Qashqai as average reliability-wise, and GLA is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as the Japanese car rank it on average as 4.6, while the one under the competitor's bonnet gets 4.2 out of 5.

Nissan 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 190 kilometers per hour, exactly the same as the other car does. When it comes to fuel economy the winner has to be the German car, averaging around 3.8 liters of fuel per 100 kilometers (74 mpg), in combined cycle. We can't ignore that 29% difference compared to the Japanese car.

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 Japanese car offers significantly better overall protection, taking the lead here. It all continues in the same direction, with Nissan offering somewhat better performance, just enough to call it quicker. It does come at a cost though, and that's the fuel consumption... It's really tough to make a final decision here, but if I'd need to, I'd say Mercedes Benz. 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.
