Well, these are two pretty similar cars we have here! It's only details that could potentially make the difference. Considering they both belong to the executive car segment and utilize the same 4-door sedan body style and the 4 x 4 wheel drive system, it all comes up to the specific petrol engine choice they offer. Both the engines are Volkswagen-engineered . The first one has a 6-cylinder, 24-valves 280hp unit, while the other one gets its power and torque from a 8-cylinder, 32-valves 420hp one.

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 that fact doesn't break the tie between the two cars. Furthermore, taking kerb weight as an important factor into account, Phaeton offers a considerable difference of 10% 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. These are the results of an independent reasearch, while our visitors describe reliability of Volkswagen, as well as Audi, with the same average rating of 4.2 out of 5. Some independent research have also placed Phaeton as average reliability-wise, and A8 is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as Phaeton rank it on average as 5.0, while the one under the competitor's bonnet gets 3.0 out of 5.

Audi is way more agile, reaching 100km/h in 4 seconds less than its competitor. In addition to that it accelerates all the way to 250 kilometers per hour, exactly the same as the other car does. When it comes to fuel economy an obvious choice would be Audi A8, averaging around 9.4 liters of fuel per 100 kilometers (30 mpg), in combined cycle. That's 22% 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 Audi outracing its opponent in any situation possible, making it better choice for boy racers. To make things even better, it consumps less fuel! All together, there's not much more to say, in this case I wouldn't even consider anything but Audi. 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.
