Virtual Adviser's™ opinion

Overview

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 sports car segment and utilize the same 2-door coupe body style and the rear wheel drive system, it all comes up to the specific petrol engine choice they offer. The first one has a Porsche-engineered powertrain under the hood, a 6-cylinder, 24-valves 530hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 320hp 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. 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 Japanese car offers a considerable difference of 12% more metal.

Reliability

I don't like generalizing things when it comes to reliability, although it does seem that Infiniti as a brand displays somewhat better results, when all the models are taken into account. These are the results of an independent reasearch, while our visitors describe reliability of Porsche with an average rating of 3.8, and models under the Infiniti badge with 4.6 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.

Performance & Fuel economy

Porsche is undoubtly more agile, reaching 100km/h in 2.1 seconds less than its competitor. In addition to that it accelerates all the way to 329 kilometers per hour, 80km/h more than the other car. When it comes to fuel economy an obvious choice would be the Japanese car, averaging around 10.5 liters of fuel per 100 kilometers (27 mpg), in combined cycle. That's 19% difference compared to the German car!


Verdict

Infiniti is apparently more reliable, not too much, but just enough. 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 Japanese 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. It does come at a cost though, and that's the fuel consumption... All together, there's not much more to say, in this case I wouldn't even consider anything but Infiniti. 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 more than 12.000 different ones in our database.
