Overview

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 6-cylinder, 18-valves 245hp unit, while the other one gets its power and torque from a 6-cylinder, 12-valves 190hp engine designed by Chrysler.

Safety

The fact that the Mercedes Benz got tested by the European New Car Assessment Programme (Euro NCAP), while the other contender didn't, offers a slight advantage, as the 4-star rating is better than none. 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, but that fact doesn't break the tie between the two cars. Furthermore, when it comes to weight, a factor that most people underestimate, the German car offers a considerable difference of 17% more metal.

Reliability

Reliability is not the best thing to consider on the make level, but it is worth mentioning that both brands display similar results in faults and breakdowns, when all the models are taken into account. These are the official statistics, while our visitors describe reliability of Mercedes Benz with an average rating of 4.3, and models under the Jeep badge with 4.0 out of 5. Some independent research have also placed ML 50% below average, and Grand Cherokee those same 50% above the first one. We should definitely mention that owners of cars with the same powertrain as the German car rank it on average as 4.1, while the one under the competitor's bonnet gets 3.0 out of 5.

Performance & Fuel economy

Mercedes Benz is undoubtly more agile, reaching 100km/h in 2.2 seconds less than its competitor. In addition to that it accelerates all the way to 205 kilometers per hour, 16km/h more than the other car. When it comes to fuel economy the winner has to be the German car, averaging around 14.1 liters of fuel per 100 kilometers (20 mpg), in combined cycle. We can't ignore that 13% difference compared to the American car.

Verdict

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 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. To make things even better, it consumps less fuel! 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.
