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. The first one has a Peugeot-engineered powertrain under the hood, a 4-cylinder, 8-valves 112hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 105hp engine designed by FIAT.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), 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, the Italian car offers a marginal difference of 1% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Citroen as a brand displays somewhat better results, all the models observed together. That's the official data, while our visitors describe reliability of Citroen with an average rating of 4.1, and models under the Alfa Romeo badge with 4.2 out of 5. Some independent research have also placed DS4 as average reliability-wise, and Giulietta is more or less at the same level.Above it all, drivers of cars with the same engine as the French car rank it on average as 4.0, while the one under the competitor's bonnet gets 2.8 out of 5.

Alfa Romeo is undoubtly more agile, reaching 100km/h in 1.1 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 185 kilometers per hour, 5km/h less than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 4.4 liters of fuel per 100 kilometers (64 mpg), in combined cycle.

Citroen 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 Italian car offers slightly better overall protection and takes the lead. It all continues in the same direction, with Alfa Romeo being considerably quicker, thus putting more smile on driver's face. Fuel consumption is more or less the same. No mistake, whatever you decide here, but I'd still go for the Alfa Romeo. 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.
