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 8-cylinder, 32-valves 420hp unit, while the other one gets its power and torque from a 8-cylinder, 40-valves 335hp 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. That aside, let's consider some other aspects which affect safety. 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. On the other hand, when it comes to weight, a factor that most people underestimate, Phaeton offers a considerable difference of 11% 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, 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. Independent research findings rank 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 3.0 out of 5, exactly the same as the other one.

Audi is undoubtly more agile, reaching 100km/h in 2.3 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 Audi A8, averaging around 9.4 liters of fuel per 100 kilometers (30 mpg), in combined cycle. That's 33% difference compared to Phaeton!

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 being considerably quicker, thus putting more smile on driver's face. 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. Nevertheless, let's not forget that people have different preferences and needs, so what really counts is your personal feel. I'm only here to help.
