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 large family 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 Alfa Romeo-engineered powertrain under the hood, a 4-cylinder, 16-valves 185hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 163hp engine designed by Peugeot.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the same number of safety stars gained in the process. That aside, let's consider some other aspects which affect safety. Both vehicles belong to the large family car segment, which is generally a good thing safety-wise, but it doesn't do much to help us decide between the two. On the other hand, taking kerb weight as an important factor into account, the French car offers a marginal difference of 2% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Peugeot is significantly less fault-prone, at least on all of the models level. These are the official statistics, while our visitors describe reliability of Alfa Romeo with an average rating of 4.2, and models under the Peugeot badge with 4.3 out of 5. The same official information place 159 as average reliability-wise, and 407 is more or less at the same level.That apart, owners of different cars powered by the same engine as the Italian car rank it on average as 4.8, while the one under the competitor's bonnet gets 4.3 out of 5.

Alfa Romeo is undoubtly more agile, reaching 100km/h in 1.8 seconds less than its competitor. In addition to that it accelerates all the way to 222 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 9.4 liters of fuel per 100 kilometers (30 mpg), in combined cycle.

Peugeot 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 offers slightly better overall protection and takes the lead. From there things take a different direction, with Alfa Romeo being considerably quicker, thus putting more smile on driver's face. Fuel consumption is more or less the same. It's really tough to make a final decision here, but if I'd need to, I'd say Alfa Romeo. Nevertheless, let's not forget that people have different preferences and needs, so what really counts is your personal feel. I'm only here to help. 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.
