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 petrol engine choice they offer. The first one has a Alfa Romeo-engineered powertrain under the hood, a 6-cylinder, 24-valves 215hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 256hp 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. Still, apart from the official crash test results there are other things we need to be aware of. 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 Italian car offers a considerable difference of 17% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Lancia does have a slight advantage, all the models observed together. That's the official data, while our visitors describe reliability of Lancia with an average rating of 4.1, and models under the Audi badge with 4.2 out of 5. Independent research findings rank Thesis as average reliability-wise, and A6 is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as the Italian car rank it on average as 3.0, while the one under the competitor's bonnet gets 4.8 out of 5.

Audi is undoubtly more agile, reaching 100km/h in 2.3 seconds less than its competitor. In addition to that it accelerates all the way to 250 kilometers per hour, 16km/h more than the other car. When it comes to fuel economy an obvious choice would be the German car, averaging around 9.7 liters of fuel per 100 kilometers (29 mpg), in combined cycle. That's 40% difference compared to the Italian 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 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. To make things even better, it consumps less fuel! All together, there's not much more to say, in this case I wouldn't even consider anything but 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™, out of 12.000+ vehicles we currently have in our database.
