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 Hyundai-engineered powertrain under the hood, a 6-cylinder, 24-valves 248hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 272hp engine designed by Mercedes Benz.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), 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. On the other hand, if we'd like to consider vehicle mass in this context too, which we definitely should, the German car offers a marginal difference of 8% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that KIA does have a slight advantage, when all the models are taken into account. These are the results of an independent reasearch, while our visitors describe reliability of KIA with an average rating of 4.6, and models under the Mercedes Benz badge with 4.4 out of 5. The same official information place Sorento as average reliability-wise, and ML is more or less at the same level.Above it all, drivers of cars with the same engine as the Korean car rank it on average as 4.0, while the one under the competitor's bonnet gets 5.0 out of 5.

Mercedes Benz is a bit more agile, reaching 100km/h in 0.8 seconds less than its competitor. In addition to that it accelerates all the way to 225 kilometers per hour, 35km/h more than the other car. When it comes to fuel economy the winner has to be the Korean car, averaging around 10.8 liters of fuel per 100 kilometers (26 mpg), in combined cycle. We can't ignore that 6% difference compared to the German car.

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 slightly better overall protection and takes the lead. It all continues in the same direction, with Mercedes Benz offering somewhat better performance, just enough to call it quicker. It does come at a cost though, and that's the fuel consumption... No mistake, whatever you decide here, but I'd still go for the KIA. Anyway, that's the most objective conclusion I could've came up with and it's based solely on the information found on this website. Aspects such as design, practicality, brand value and driving experience are there for you to measure them out.
