Overview

Two significantly similar cars, no doubt about that. Still, each one has something different to offer. Having both cars powered by hybrid 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 (front for the DS and rear in the case of the Mercedes Benz). The first one has a Peugeot-engineered powertrain under the hood, a 4-cylinder, 16-valves 225hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 306hp engine designed by Mercedes Benz.

Safety

A starting point here would be to take a look at the results from European New Car Assessment Programme (Euro NCAP) tests which were performed on both of the cars, with the Mercedes Benz being a slightly better choice apparently. Moving further on, let's take a closer look at some additional safety-related facts. Both vehicles belong to the luxury car segment, which is generally a very good thing safety-wise, but it doesn't do much to help us decide between the two. On the other hand, when it comes to weight, a factor that most people underestimate, the German car offers a marginal difference of 8% more metal.

Reliability

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that DS as a brand displays somewhat better results, at least on all of the models level. That's the official data, while our visitors describe reliability of DS with an average rating of 4.0, and models under the Mercedes Benz badge with 4.3 out of 5. Unfortunatelly, I don't have enough insight that would allow me to comment in more details on the specific models level. That apart, owners of different cars powered by the same engine as the French car rank it on average as 3.0 out of 5, exactly the same as the other one.

Performance & Fuel economy

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 240 kilometers per hour, exactly the same as the other car does. When it comes to fuel economy things look pretty much the same for both cars, averaging around 1.6 liters of fuel per 100 kilometers (177 mpg), in combined cycle.

Verdict

DS 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 much better overall protection, which launches it ahead of the other contender. It all continues in the same direction, with Mercedes Benz being considerably quicker, thus putting more smile on driver's face. Fuel consumption is more or less the same. It's not difficult to say then that if I'd need to make a choice, it would definitely be the 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.
