Two significantly similar cars, no doubt about that. Still, each one has something different to offer. Having both cars powered by diesel engines and utilizing the 4-door sedan body style within the same 'Luxury car' segment, the only major difference here really is their wheel drive configuration (4 x 4 for the Audi and front in the case of the Volvo). Both the engines are Audi-engineered . The first one has a 6-cylinder, 24-valves 233hp unit, while the other one gets its power and torque from a 5-cylinder, 20-valves 140hp one.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the Audi being a slightly better choice apparently. 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.

I don't like generalizing things when it comes to reliability, although it does seem that Volvo does have a slight advantage, when all the models are taken into account. These are the results of an independent reasearch, 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. The same official information place A6 as average reliability-wise, and S80 is more or less at the same level.That apart, owners of different cars powered by the same engine as the German car rank it on average as 4.6, while the one under the competitor's bonnet gets 3.0 out of 5.

There's not enough data for me to elaborate on the subject, I'm affraid.

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. When it comes to performance, both vehicles provide similar experience, so I wouldn't point any of them out. Fuel consumption is more or less the same. No mistake, whatever you decide here, but I'd still go for the Audi. Anyway, that's the most objective conclusion I could've came up with and it's based solely on the information found on this website. Aspects such as design, practicality, brand value and driving experience are there for you to measure them out.
