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 petrol engine choice they offer. Both the engines are Alfa Romeo-engineered . The first one has a 4-cylinder, 16-valves 240hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 200hp 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. Moving further on, let's take a closer look at some additional safety-related facts. 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, when it comes to weight, a factor that most people underestimate, Delta offers a marginal difference of 8% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning that Lancia as a brand displays somewhat better results, at least on all of the models level. That's the official data, 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.Above it all, drivers of cars with the same engine as Giulietta rank it on average as 3.0, while the one under the competitor's bonnet gets 3.4 out of 5.

Alfa Romeo 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 242 kilometers per hour, 12km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 7.7 liters of fuel per 100 kilometers (37 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, Delta offers slightly better overall protection and takes the lead. From there things take a different direction, with Alfa Romeo offering somewhat better performance, just enough to call it quicker. To make things even better, it consumps less fuel! It's really tough to make a final decision here, but if I'd need to, I'd say Alfa Romeo. 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.
