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 'Executive car' segment, the only major difference here really is their wheel drive configuration (rear for the Mercedes Benz and 4 x 4 in the case of the Volkswagen). The first one has a Mercedes Benz-engineered powertrain under the hood, a 8-cylinder, 32-valves 316hp unit, while the other one gets its power and torque from a 10-cylinder, 20-valves 313hp engine designed by Volkswagen.

Unfortunatelly, neither of the two vehicles was submitted to the European New Car Assessment Programme (Euro NCAP) testing. This makes it virtually impossible for me to pick one over the other and I'm generally against buying such cars as the safety should really always come first. Moving further on, let's take a closer look at some additional safety-related facts. Both vehicles belong to the executive car segment, which is generally a fortune safety-wise, but it doesn't do much to help us decide between the two. On the other hand, if we'd like to consider vehicle mass in this context too, which we definitely should, Phaeton offers a considerable difference of 22% 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, at least on all of the models level. That's the official data, while our visitors describe reliability of Mercedes Benz with an average rating of 4.4, and models under the Volkswagen badge with 4.2 out of 5. Some independent research have also placed S as average reliability-wise, and Phaeton is more or less at the same level.Above it all, drivers of cars with the same engine as Mercedes Benz S rank it on average as 3.0, while the one under the competitor's bonnet gets 4.7 out of 5.

Mercedes Benz 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 250 kilometers per hour, exactly the same as the other car does. When it comes to fuel economy an obvious choice would be Mercedes Benz S, averaging around 9.4 liters of fuel per 100 kilometers (30 mpg), in combined cycle. That's 21% difference compared to Phaeton!

Volkswagen 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, Phaeton offers significantly better overall protection, taking the lead here. From there things take a different direction, with Mercedes Benz offering somewhat better performance, just enough to call it quicker. To make things even better, it consumps less fuel! It's not difficult to say then that if I'd need to make a choice, it would definitely be the 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.
