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 (4 x 4 for the Mercedes Benz and front in the case of the Mazda). The first one has a Mercedes Benz-engineered powertrain under the hood, a 6-cylinder, 24-valves 367hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 192hp engine designed by Mazda.

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 large family car segment, which is generally a good thing safety-wise, but that fact doesn't break the tie between the two cars.

I don't like generalizing things when it comes to reliability, although it does seem that Mazda as a brand displays somewhat better results, all the models observed together. These are the results of an independent reasearch, while our visitors describe reliability of Mercedes Benz, as well as Mazda, with the same average rating of 4.4 out of 5. Some independent research have also placed C as average reliability-wise, and 6 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 1.0, while the one under the competitor's bonnet gets 3.0 out of 5.

There's not enough data for me to elaborate on the subject, I'm affraid.

Mazda 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 this case though, it seems that both cars show similar levels of passenger protection all together, so that won't break a tie. When it comes to performance, both vehicles provide similar experience, so I wouldn't point any of them out. Fuel consumption is more or less the same. No mistake, whatever you decide here, but I'd still go for the Mazda. 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.
