Well, these are two pretty similar cars we have here! It's only details that could potentially make the difference. Considering they both belong to the suv segment and utilize the same 5-door suv body style and the front wheel drive system, it all comes up to the specific diesel engine choice they offer. The first one has a Mazda-engineered powertrain under the hood, a 4-cylinder, 16-valves 105hp unit, while the other one gets its power and torque from a 4-cylinder, 8-valves 110hp engine designed by Renault.

A starting point here would be to take a look at the results from European New Car Assessment Programme (Euro NCAP) tests which were performed on both of the cars, with the Mercedes Benz 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, but that fact doesn't break the tie between the two cars. On the other hand, when it comes to weight, a factor that most people underestimate, the German car offers a marginal difference of 2% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Mazda as a brand displays somewhat better results, at least on all of the models level. These are the official statistics, while our visitors describe reliability of Mazda with an average rating of 4.4, and models under the Mercedes Benz badge with 4.3 out of 5. Independent research findings rank CX-3 as average reliability-wise, and GLA is more or less at the same level.That apart, owners of different cars powered by the same engine as the Japanese car rank it on average as 1.0, while the one under the competitor's bonnet gets 4.3 out of 5.

Mazda is undoubtly more agile, reaching 100km/h in 1.2 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 177 kilometers per hour, 13km/h less than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 3.9 liters of fuel per 100 kilometers (72 mpg), in combined cycle.

Mercedes Benz 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 German car offers much better overall protection, which launches it ahead of the other contender. When it comes to performance, both vehicles provide similar experience, so I wouldn't point any of them out. the German car still consumps less fuel, which needs to be taken into consideration. All together, there's not much more to say, in this case I wouldn't even consider anything but Mercedes Benz. Nevertheless, let's not forget that people have different preferences and needs, so what really counts is your personal feel. I'm only here to help. 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.
