Overview

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 12-cylinder, 48-valves 450hp unit, while the other one gets its power and torque from a 12-cylinder, 48-valves 420hp one.

Safety

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. On the other hand, taking kerb weight as an important factor into account, Phaeton offers a considerable difference of 16% more metal.

Reliability

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. 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 50% below average, and Phaeton is more or less at the same level.That apart, owners of different cars powered by the same engine as Audi A8 rank it on average as 2.3, while the one under the competitor's bonnet gets 2.0 out of 5.

Performance & Fuel economy

Audi is undoubtly more agile, reaching 100km/h in 1 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 the winner has to be Audi A8, averaging around 14.7 liters of fuel per 100 kilometers (19 mpg), in combined cycle. We can't ignore that 6% difference compared to Phaeton.

Verdict

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! It's not difficult to say then that if I'd need to make a choice, it would definitely be the 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.
