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 Hyundai). The first one has a Audi-engineered powertrain under the hood, a 6-cylinder, 24-valves 240hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 150hp engine designed by Hyundai.

A starting point here would be to take a look at the results from European New Car Assessment Programme (Euro NCAP) tests which were performed on both of the cars, with the Audi being a slightly better choice apparently. 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 that fact doesn't break the tie between the two cars. Furthermore, taking kerb weight as an important factor into account, the German car offers a considerable difference of 13% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears 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.Above it all, drivers of cars with the same engine as the German car rank it on average as 5.0 out of 5, exactly the same as the other one.

Audi is way more agile, reaching 100km/h in 4.1 seconds less than its competitor. In addition to that it accelerates all the way to 250 kilometers per hour, 47km/h more than the other car. When it comes to fuel economy the winner has to be the Korean car, averaging around 6 liters of fuel per 100 kilometers (47 mpg), in combined cycle. We can't ignore that 12% difference compared to the German car.

Hyundai 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 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... 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. 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.
