Well, these are two pretty similar cars we have here! It's only details that could potentially make the difference. Not only that they both belong to the executive car segment and utilize the same 4-door sedan body style, they are even powered by the same Audi-developed diesel engine! There is not much there to point us towards one vehicle or the other. Or is it?

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, still it doesn't help us solve our dilemma, does it? On the other hand, when it comes to weight, a factor that most people underestimate, Phaeton offers a considerable difference of 22% 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. That's the official data, while our visitors describe reliability of Audi, as well as Volkswagen, with the same average rating of 4.2 out of 5. The same official information place A8 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 these two vehicles rank it on average as 4.6 out of 5.

Audi is a bit more agile, reaching 100km/h in 0.9 seconds less than its competitor. In addition to that it accelerates all the way to 243 kilometers per hour, 7km/h more than the other car. When it comes to fuel economy the winner has to be Audi A8, averaging around 8.5 liters of fuel per 100 kilometers (33 mpg), in combined cycle. We can't ignore that 12% 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! 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. Also, you could use the oportunity to find out which car, everything taken into account, would be the perfect choice for you in the eyes of the virtual adviser™, among thousands of similar, yet so different vehicles.
