Virtual Adviser's™ opinion
Two significantly similar cars, no doubt about that. Still, each one has something different to offer. Having both cars powered by diesel engines and utilizing the 4-door sedan body style within the same 'Luxury 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 Hyundai). The first one has a Mercedes Benz-engineered powertrain under the hood, a 6-cylinder, 24-valves 211hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 150hp engine designed by Hyundai.
SafetyBoth vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the Mercedes Benz being a slightly better choice apparently. That aside, let's consider some other aspects which affect safety. Both vehicles belong to the luxury car segment, which is generally a very good thing safety-wise, but that fact doesn't break the tie between the two cars. Furthermore, if we'd like to consider vehicle mass in this context too, which we definitely should, the German car offers a marginal difference of 5% more metal.
ReliabilityI don't like generalizing things when it comes to reliability, although it does seem that Hyundai as a brand displays somewhat better results, at least on all of the models level. These are the official statistics, while our visitors describe reliability of Mercedes Benz with an average rating of 4.4, and models under the Hyundai badge with 4.5 out of 5. The same official information place E as average reliability-wise, and Sonata is more or less at the same level.That apart, owners of different cars powered by the same engine as the German car rank it on average as 3.0, while the one under the competitor's bonnet gets 5.0 out of 5.
Performance & Fuel economyMercedes Benz is way more agile, reaching 100km/h in 3.5 seconds less than its competitor. In addition to that it accelerates all the way to 244 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 6 liters of fuel per 100 kilometers (47 mpg), in combined cycle. We can't ignore that 20% difference compared to the German car.
Verdict
Hyundai 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 offers much better overall protection, which launches it ahead of the other contender. 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... At the end, as much as I'd like to give you a winner here, it's simply a pure tie if you ask me. 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.
