Virtual Adviser's™ opinion
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 Volkswagen-developed petrol engine! There is not much there to point us towards one vehicle or the other. Or is it?
SafetyUnfortunatelly, 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, still it doesn't help us solve our dilemma, does it? Furthermore, when it comes to weight, a factor that most people underestimate, Phaeton offers a considerable difference of 21% more metal.
ReliabilityManufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Volkswagen does have a slight advantage, all the models observed together. These are the official statistics, 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 these two vehicles rank it on average as 3.0 out of 5.
Performance & Fuel economyAudi is a bit more agile, reaching 100km/h in 0.6 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 the winner has to be Audi A8, averaging around 11.9 liters of fuel per 100 kilometers (24 mpg), in combined cycle. We can't ignore that 10% 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 offering somewhat better performance, just enough to call it quicker. To make things even better, it consumps less fuel! No mistake, whatever you decide here, but I'd still go for the 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. 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™, among thousands of similar, yet so different vehicles.
