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 2-door cabriolet body style within the same 'Sports car' segment, the only major difference here really is their wheel drive configuration (rear for the Porsche and 4 x 4 in the case of the Alfa Romeo). The first one has a Porsche-engineered powertrain under the hood, a 6-cylinder, 24-valves 280hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 260hp engine designed by Alfa Romeo.

Unfortunatelly, neither of the two vehicles was submitted to the European New Car Assessment Programme (Euro NCAP) testing. This makes it virtually impossible for me to pick one over the other and I'm generally against buying such cars as the safety should really always come first. Still, apart from the official crash test results there are other things we need to be aware of. Both vehicles belong to the sports 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 considerable difference of 24% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning that both brands display similar results in faults and breakdowns, at least on all of the models level. These are the official statistics, while our visitors describe reliability of Porsche with an average rating of 3.7, and models under the Alfa Romeo badge with 4.2 out of 5. Unfortunatelly, I don't have enough insight that would allow me to comment in more details on the specific models level. We should definitely mention that owners of cars with the same powertrain as the German car rank it on average as 3.0, while the one under the competitor's bonnet gets 5.0 out of 5.

Porsche is undoubtly more agile, reaching 100km/h in 1.5 seconds less than its competitor. In addition to that it accelerates all the way to 268 kilometers per hour, 28km/h more than the other car. When it comes to fuel economy the winner has to be the German car, averaging around 10.4 liters of fuel per 100 kilometers (27 mpg), in combined cycle. We can't ignore that 11% difference compared to the Italian car.

Alfa Romeo 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 significantly better overall protection, taking the lead here. From there things take a different direction, with Porsche being considerably quicker, thus putting more smile on driver's face. To make things even better, it consumps less fuel! I believe that, when we take all into account, we have only one winner here - the Porsche. 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.
