Two significantly similar cars, no doubt about that. Still, each one has something different to offer. Having both cars powered by petrol 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 Hyundai). The first one has a Volkswagen-engineered powertrain under the hood, a 6-cylinder, 30-valves 250hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 175hp engine designed by Hyundai.

The fact that the Audi got tested by the European New Car Assessment Programme (Euro NCAP), while the other contender didn't, isn't really an advantage, taken the poor 3-star rating it received. That aside, let's consider some other aspects which affect safety. Both vehicles belong to the luxury car segment, which is generally a very good thing safety-wise, but it doesn't do much to help us decide between the two. Furthermore, taking kerb weight as an important factor into account, the German car offers a considerable difference of 15% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning that Hyundai as a brand displays somewhat better results, 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 Hyundai badge with 4.5 out of 5. Independent research findings rank A6 as average reliability-wise, and Sonata 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 2.5, while the one under the competitor's bonnet gets 5.0 out of 5.

Audi is undoubtly more agile, reaching 100km/h in 2.9 seconds less than its competitor. In addition to that it accelerates all the way to 248 kilometers per hour, 38km/h more than the other car. When it comes to fuel economy the winner has to be the Korean car, averaging around 10.7 liters of fuel per 100 kilometers (26 mpg), in combined cycle. We can't ignore that 8% difference compared to the German car.

Hyundai is apparently more reliable, not too much, but just enough. 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 being considerably quicker, thus putting more smile on driver's face. It does come at a cost though, and that's the fuel consumption... At the end, as much as I'd like to give you a winner here, it's simply a pure tie if you ask me. 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.
