Two significantly similar cars, no doubt about that. Still, each one has something different to offer. Having both cars powered by petrol 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 Mercedes Benz and front in the case of the FIAT). The first one has a Mercedes Benz-engineered powertrain under the hood, a 4-cylinder, 16-valves 360hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 110hp engine designed by FIAT.

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. Still, apart from the official crash test results there are other things we need to be aware of. 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? Furthermore, if we'd like to consider vehicle mass in this context too, which we definitely should, the German car offers a considerable difference of 14% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that FIAT as a brand displays somewhat better results, at least on all of the models level. These are the results of an independent reasearch, while our visitors describe reliability of Mercedes Benz, as well as FIAT, with the same average rating of 4.3 out of 5. The same official information place GLA as average reliability-wise, and 500X is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as the German car rank it on average as 3.5, while the one under the competitor's bonnet gets 3.3 out of 5.

Mercedes Benz is way more agile, reaching 100km/h in 6.9 seconds less than its competitor. In addition to that it accelerates all the way to 250 kilometers per hour, 70km/h more than the other car. When it comes to fuel economy the winner has to be the Italian car, averaging around 6 liters of fuel per 100 kilometers (47 mpg), in combined cycle. We can't ignore that 15% difference compared to the German car.

FIAT 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 beats the other contender by far, making it the best choice without even considering other things. It all continues in the same direction, with Mercedes Benz outracing its opponent in any situation possible, making it better choice for boy racers. It does come at a cost though, and that's the fuel consumption... All together, there's not much more to say, in this case I wouldn't even consider anything but 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. Also, you could use the oportunity to find out which car, everything taken into account, would be the perfect choice for you in the eyes of the virtual adviser™, among thousands of similar, yet so different vehicles.
