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 Audi being a executive car and the Volvo representing luxury car vehicle class. The first one has a Volkswagen-engineered powertrain under the hood, a 12-cylinder, 48-valves 500hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 243hp engine designed by Volvo.

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 first 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, if we'd like to consider vehicle mass in this context too, which we definitely should, the German car offers a considerable difference of 25% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning that Volvo 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 with an average rating of 4.2, and models under the Volvo badge with 4.6 out of 5. Some independent research have also placed A8 as average reliability-wise, and S80 is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as the German car rank it on average as 5.0, while the one under the competitor's bonnet gets 3.0 out of 5.

Audi is way more agile, reaching 100km/h in 3.5 seconds less than its competitor. In addition to that it accelerates all the way to 250 kilometers per hour, 15km/h more than the other car. When it comes to fuel economy an obvious choice would be the Swedish car, averaging around 9.4 liters of fuel per 100 kilometers (30 mpg), in combined cycle. That's 32% difference compared to the German 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 much better overall protection, which launches it ahead of the other contender. It all continues in the same direction, with Audi outracing its opponent in any situation possible, making it better choice for boy racers. It does come at a cost though, and that's the fuel consumption... It's really tough to make a final decision here, but if I'd need to, I'd say 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. 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.
