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 small family car segment and utilize the same 5-door hatchback body style and the front wheel drive system, it all comes up to the specific diesel engine choice they offer. Both the engines are FIAT-engineered . The first one has a 4-cylinder, 16-valves 105hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 120hp one.

The first thing to look into here would be the results from European New Car Assessment Programme (Euro NCAP) tests performed on the two cars. Good thing is that both vehicles got tested, with the same number of safety stars gained in the process. Still, apart from the official crash test results there are other things we need to be aware of. Both vehicles belong to the small family car segment, which is generally classifying them somewhere in the middle safety-wise, but that fact doesn't break the tie between the two cars. On the other hand, if we'd like to consider vehicle mass in this context too, which we definitely should, Delta offers a marginal difference of 8% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Lancia as a brand displays somewhat better results, all the models observed together. These are the official statistics, while our visitors describe reliability of Alfa Romeo with an average rating of 4.2, and models under the Lancia badge with 4.1 out of 5. Some independent research have also placed Giulietta as average reliability-wise, and Delta is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as Giulietta rank it on average as 2.8, while the one under the competitor's bonnet gets 4.3 out of 5.

Lancia is a bit more agile, reaching 100km/h in 0.6 seconds less than its competitor. In addition to that it accelerates all the way to 194 kilometers per hour, 9km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 4.6 liters of fuel per 100 kilometers (61 mpg), in combined cycle.

Lancia 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, Delta offers slightly better overall protection and takes the lead. It all continues in the same direction, with Lancia offering somewhat better performance, just enough to call it quicker. It does come at a cost though, and that's the fuel consumption... It's really tough to make a final decision here, but if I'd need to, I'd say Lancia. Anyway, that's the most objective conclusion I could've came up with and it's based solely on the information found on this website. Aspects such as design, practicality, brand value and driving experience are there for you to measure them out. 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.
