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 'Large family car' segment, the only major difference here really is their wheel drive configuration (4 x 4 for the Volkswagen and front in the case of the Mercedes Benz). The first one has a Volkswagen-engineered powertrain under the hood, a 4-cylinder, 16-valves 177hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 136hp engine designed by Mercedes Benz.

The fact that the Mercedes Benz got tested by the European New Car Assessment Programme (Euro NCAP), while the other contender didn't, puts it sky-high safety-wise, in my eyes at least. Moving further on, let's take a closer look at some additional safety-related facts. Both vehicles belong to the large family car segment, which is generally a good thing safety-wise, still it doesn't help us solve our dilemma, does it? Furthermore, taking kerb weight as an important factor into account, Passat CC offers a marginal difference of 7% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning that Volkswagen does have a slight advantage, all the models observed together. That's the official data, while our visitors describe reliability of Volkswagen with an average rating of 4.2, and models under the Mercedes Benz badge with 4.3 out of 5. Some independent research have also placed Passat CC as average reliability-wise, and CLA is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as Passat CC rank it on average as 3.9, while the one under the competitor's bonnet gets 5.0 out of 5.

Volkswagen is a bit more agile, reaching 100km/h in 0.9 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 220 kilometers per hour, exactly the same as the other car does. When it comes to fuel economy the winner has to be CLA, averaging around 4.4 liters of fuel per 100 kilometers (64 mpg), in combined cycle. We can't ignore that 30% difference compared to Passat CC.

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, CLA beats the other contender by far, making it the best choice without even considering other things. From there things take a different direction, with Volkswagen offering somewhat better performance, just enough to call it quicker. 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. 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.
