We are here considering two somewhat similar cars, but we can't deny some of the obvious differences. For a start, they are not even classified under the same segment, with the Volvo being a luxury car and the Audi representing executive car vehicle class. The first one has a Volvo-engineered powertrain under the hood, a 8-cylinder, 32-valves 315hp unit, while the other one gets its power and torque from a 8-cylinder, 32-valves 350hp engine designed by Volkswagen.

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. The second vehicle is a executive car and that gives it a marginal advantage over the luxury car competitor, at least that's what statistics show. Furthermore, taking kerb weight as an important factor into account, the German car offers a marginal difference of 5% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Volvo does have a slight advantage, at least on all of the models level. These are the official statistics, while our visitors describe reliability of Volvo with an average rating of 4.6, and models under the Audi badge with 4.2 out of 5. Some independent research have also placed S80 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 the Swedish car rank it on average as 3.0, while the one under the competitor's bonnet gets 4.9 out of 5.

Audi is a bit more agile, reaching 100km/h in 0.4 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 the German car, averaging around 10.9 liters of fuel per 100 kilometers (26 mpg), in combined cycle. We can't ignore that 9% difference compared to the Swedish car.

Audi 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, the German car offers significantly better overall protection, taking the lead here. It all continues in the same direction, with Audi offering somewhat better performance, just enough to call it quicker. 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. 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.
