Virtual Adviser's™ opinion

Overview

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 (front for the Alfa Romeo and rear in the case of the Nissan). 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 300hp engine designed by Nissan.

Safety

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. Moving further on, let's take a closer look at some additional safety-related facts. Both vehicles belong to the sports car segment, which is generally classifying them somewhere in the middle safety-wise, but it doesn't do much to help us decide between the two. Furthermore, if we'd like to consider vehicle mass in this context too, which we definitely should, the Italian car offers a marginal difference of 2% more metal.

Reliability

I don't like generalizing things when it comes to reliability, although it does seem that Nissan 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 Nissan badge with 4.3 out of 5. The same official information place Brera as average reliability-wise, and 350Z 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 out of 5, exactly the same as the other one.

Performance & Fuel economy

Nissan is a bit more agile, reaching 100km/h in 0.7 seconds less than its competitor. In addition to that it accelerates all the way to 250 kilometers per hour, 10km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 11.8 liters of fuel per 100 kilometers (24 mpg), in combined cycle.


Verdict

Nissan 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. From there things take a different direction, with Nissan offering somewhat better performance, just enough to call it quicker. 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 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. Also, you could use the oportunity to find out which car, everything taken into account, would be the perfect choice for you in the eyes of the virtual adviser, among thousands of similar, yet so different vehicles.
