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 diesel engine choice they offer. The first one has a Mercedes Benz-engineered powertrain under the hood, a 5-cylinder, 10-valves 163hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 140hp engine designed by Hyundai.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the same number of safety stars gained in the process. 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, when it comes to weight, a factor that most people underestimate, the German car offers a marginal difference of 6% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning that KIA does have a slight advantage, all the models observed together. These are the results of an independent reasearch, while our visitors describe reliability of Mercedes Benz with an average rating of 4.4, and models under the KIA badge with 4.6 out of 5. Independent research findings rank ML as average reliability-wise, and Sorento is more or less at the same level.Above it all, drivers of cars with the same engine as the German car rank it on average as 4.4, while the one under the competitor's bonnet gets 5.0 out of 5.

Mercedes Benz is undoubtly more agile, reaching 100km/h in 2.4 seconds less than its competitor. In addition to that it accelerates all the way to 185 kilometers per hour, 15km/h more than the other car. When it comes to fuel economy the winner has to be the Korean car, averaging around 7.7 liters of fuel per 100 kilometers (37 mpg), in combined cycle. We can't ignore that 22% difference compared to the German car.

KIA 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 being considerably quicker, thus putting more smile on driver's face. 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. 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.
