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 4 x 4 wheel drive system, it all comes up to the specific petrol engine choice they offer. The first one has a Mercedes Benz-engineered powertrain under the hood, a 4-cylinder, 16-valves 306hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 300hp engine designed by Volkswagen.

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 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, still it doesn't help us solve our dilemma, does it? Furthermore, when it comes to weight, a factor that most people underestimate, GLA 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 Volkswagen does have a slight advantage, at least on all of the models level. That's the official data, while our visitors describe reliability of Mercedes Benz with an average rating of 4.3, and models under the Volkswagen badge with 4.2 out of 5. Unfortunatelly, I don't have enough insight that would allow me to comment in more details on the specific models level. Above it all, drivers of cars with the same engine as GLA rank it on average as 3.0, while the one under the competitor's bonnet gets 5.0 out of 5.

Volkswagen is a bit more agile, reaching 100km/h in 0.3 seconds less than its competitor. In addition to that it accelerates all the way to 250 kilometers per hour, exactly the same as the other car does. When it comes to fuel economy the winner has to be T-Roc, averaging around 7.8 liters of fuel per 100 kilometers (36 mpg), in combined cycle. We can't ignore that 18% difference compared to GLA.

Volkswagen 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, GLA offers significantly better overall protection, taking the lead here. From there things take a different direction, with Volkswagen offering somewhat better performance, just enough to call it quicker. To make things even better, it consumps less fuel! It's not difficult to say then that if I'd need to make a choice, it would definitely be the Volkswagen. 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.
