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 4-door sedan body style within the same 'Large family car' segment, the only major difference here really is their wheel drive configuration (rear for the Mercedes Benz and front in the case of the KIA). The first one has a Mercedes Benz-engineered powertrain under the hood, a 6-cylinder, 18-valves 354hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 170hp engine designed by Hyundai.

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. That aside, let's consider some other aspects which affect safety. Both vehicles belong to the large family car segment, which is generally a good thing safety-wise, but it doesn't do much to help us decide between the two. 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 10% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that KIA does have a slight advantage, at least on all of the models level. These are the results of an independent reasearch, while our visitors describe reliability of Mercedes Benz with an average rating of 4.3, and models under the KIA badge with 4.2 out of 5. Independent research findings rank C as average reliability-wise, and Magentis 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 3.0, while the one under the competitor's bonnet gets 1.0 out of 5.

Mercedes Benz is way more agile, reaching 100km/h in 3.6 seconds less than its competitor. In addition to that it accelerates all the way to 250 kilometers per hour, 41km/h more than the other car. When it comes to fuel economy the winner has to be the Korean car, averaging around 10.3 liters of fuel per 100 kilometers (27 mpg), in combined cycle. We can't ignore that 12% difference compared to the German car.

Mercedes Benz is apparently more reliable, not too much, but just enough. 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. 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. 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.
