Virtual Adviser's™ opinion
Two significantly similar cars, no doubt about that. Still, each one has something different to offer. Having both cars powered by petrol engines and utilizing the 4-door sedan body style within the same 'Large family car' segment, the only major difference here really is their wheel drive configuration (4 x 4 for the Alfa Romeo and front in the case of the Peugeot). The first one has a Alfa Romeo-engineered powertrain under the hood, a 6-cylinder, 24-valves 260hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 210hp engine designed by Peugeot.
SafetyBoth vehicles got tested by European New Car Assessment Programme (Euro NCAP), 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 large family car segment, which is generally a good thing safety-wise, still it doesn't help us solve our dilemma, does it? Furthermore, taking kerb weight as an important factor into account, the Italian car offers a marginal difference of 6% more metal.
ReliabilityI don't like generalizing things when it comes to reliability, although it does seem 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. Some independent research have also placed 159 as average reliability-wise, and 407 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 4.0 out of 5.
Performance & Fuel economyAlfa Romeo is undoubtly more agile, reaching 100km/h in 1.4 seconds less than its competitor. In addition to that it accelerates all the way to 240 kilometers per hour, 5km/h more than the other car. When it comes to fuel economy the winner has to be the French car, averaging around 9.8 liters of fuel per 100 kilometers (29 mpg), in combined cycle. We can't ignore that 17% difference compared to the Italian car.
Verdict
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 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. 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 Peugeot. 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.
