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 luxury car segment and utilize the same 4-door sedan body style and the front wheel drive system, it all comes up to the specific diesel engine choice they offer. The first one has a Volvo-engineered powertrain under the hood, a 5-cylinder, 20-valves 163hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 170hp engine designed by Volkswagen.

The fact that the Audi got tested by the European New Car Assessment Programme (Euro NCAP), while the other contender didn't, puts it sky-high safety-wise, in my eyes at least. Moving further on, let's take a closer look at some additional safety-related facts. Both vehicles belong to the luxury car segment, which is generally a very good thing safety-wise, but that fact doesn't break the tie between the two cars. On the other hand, if we'd like to consider vehicle mass in this context too, which we definitely should, the German car offers a marginal difference of 4% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears 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 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 A6 is more or less at the same level.Above it all, drivers of cars with the same engine as the Swedish car rank it on average as 4.9, while the one under the competitor's bonnet gets 4.2 out of 5.

Audi is a bit more agile, reaching 100km/h in 0.8 seconds less than its competitor. In addition to that it accelerates all the way to 225 kilometers per hour, 10km/h more than the other car. When it comes to fuel economy the winner has to be the Swedish car, averaging around 4.9 liters of fuel per 100 kilometers (58 mpg), in combined cycle. We can't ignore that 16% difference compared to the German car.

Volvo 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 beats the other contender by far, making it the best choice without even considering other things. It all continues in the same direction, with Audi offering somewhat better performance, just enough to call it quicker. It does come at a cost though, and that's the fuel consumption... 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.
