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 (rear for the Infiniti and 4 x 4 in the case of the Porsche). The first one has a Nissan-engineered powertrain under the hood, a 6-cylinder, 24-valves 320hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 480hp engine designed by Porsche.

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, still it doesn't help us solve our dilemma, does it? Furthermore, when it comes to weight, a factor that most people underestimate, the Japanese car offers a considerable difference of 14% 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, at least on all of the models level. These are the results of an independent reasearch, while our visitors describe reliability of Infiniti with an average rating of 4.6, and models under the Porsche badge with 3.8 out of 5. Unfortunatelly, I don't have enough insight that would allow me to comment in more details on the specific models level. Above it all, drivers of cars with the same engine as the Japanese car rank it on average as 5.0, while the one under the competitor's bonnet gets 3.0 out of 5.

Performance & Fuel economy

Porsche is undoubtly more agile, reaching 100km/h in 2.2 seconds less than its competitor. In addition to that it accelerates all the way to 310 kilometers per hour, 60km/h more than the other car. When it comes to fuel economy the winner has to be the Japanese car, averaging around 11.9 liters of fuel per 100 kilometers (24 mpg), in combined cycle. We can't ignore that 8% 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. Anyway, that's the most objective conclusion I could've came up with and it's based solely on the information found on this website. Aspects such as design, practicality, brand value and driving experience are there for you to measure them out. 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, out of 12.000+ vehicles we currently have in our database.
