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 diesel engine choice they offer. Both the engines are Audi-engineered . The first one has a 8-cylinder, 32-valves 275hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 240hp 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. Still, apart from the official crash test results there are other things we need to be aware of. 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, when it comes to weight, a factor that most people underestimate, Phaeton offers a considerable difference of 15% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Volkswagen does have a slight advantage, when all the models are taken into account. These are the official statistics, while our visitors describe reliability of Audi, as well as Volkswagen, with the same average rating of 4.2 out of 5. Some independent research have also placed A8 as average reliability-wise, and Phaeton is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as Audi A8 rank it on average as 4.5, while the one under the competitor's bonnet gets 5.0 out of 5.

Audi is undoubtly more agile, reaching 100km/h in 1.9 seconds less than its competitor. In addition to that it accelerates all the way to 250 kilometers per hour, 13km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 9.4 liters of fuel per 100 kilometers (30 mpg), in combined cycle.

Volkswagen 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, 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. It does come at a cost though, and that's the fuel consumption... At the end, as much as I'd like to give you a winner here, it's simply a pure tie if you ask me. 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. In case you have two minutes to spare I invite you to define your needs, desires and budget and see which car would be chosen by the virtual adviser™, out of 12.000+ vehicles we currently have in our database.
