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 FIAT-engineered powertrain under the hood, a 5-cylinder, 10-valves 150hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 180hp 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 it doesn't do much to help us decide between the two. Furthermore, if we'd like to consider vehicle mass in this context too, which we definitely should, the Italian car offers a marginal difference of 9% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Lancia does have a slight advantage, at least on all of the models level. These are the official statistics, 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. The same official information place 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 3.3, while the one under the competitor's bonnet gets 4.3 out of 5.

Audi is undoubtly more agile, reaching 100km/h in 2 seconds less than its competitor. In addition to that it accelerates all the way to 230 kilometers per hour, 24km/h more than the other car. When it comes to fuel economy the winner has to be the German car, averaging around 7 liters of fuel per 100 kilometers (40 mpg), in combined cycle. We can't ignore that 17% 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.
