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 FIAT-engineered powertrain under the hood, a 5-cylinder, 20-valves 185hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 215hp engine designed by Peugeot.

The fact that the Citroen 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 that fact doesn't break the tie between the two cars. On the other hand, when it comes to weight, a factor that most people underestimate, the French car offers a marginal difference of 2% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning that both brands display similar results in faults and breakdowns, at least on all of the models level. That's the official data, while our visitors describe reliability of Lancia with an average rating of 4.3, and models under the Citroen badge with 4.0 out of 5. The same official information place Thesis as average reliability-wise, and C6 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 5.0, while the one under the competitor's bonnet gets 3.0 out of 5.

Lancia is a bit more agile, reaching 100km/h in 0.5 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 224 kilometers per hour, 6km/h less than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 11.2 liters of fuel per 100 kilometers (25 mpg), in combined cycle.

Lancia 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 French car beats the other contender by far, making it the best choice without even considering other things. When it comes to performance, both vehicles provide similar experience, so I wouldn't point any of them out. the Italian car still consumps less fuel, which needs to be taken into consideration. All together, there's not much more to say, in this case I wouldn't even consider anything but Citroen. 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™, among thousands of similar, yet so different vehicles.
