Virtual Adviser's™ opinion
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 4 x 4 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 430hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 485hp engine designed by Nissan.
SafetyUnfortunatelly, 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. That aside, let's consider some other aspects which affect safety. 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, taking kerb weight as an important factor into account, the Japanese car offers a considerable difference of 18% more metal.
ReliabilityI 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. That's the official data, while our visitors describe reliability of Porsche with an average rating of 3.7, and models under the Nissan badge with 4.3 out of 5. Independent research findings rank 911 as average reliability-wise, and GT-R is more or less at the same level.Above it all, drivers of cars with the same engine as the German car rank it on average as 3.0 out of 5, exactly the same as the other one.
Performance & Fuel economyNissan is a bit more agile, reaching 100km/h in 0.9 seconds less than its competitor. In addition to that it accelerates all the way to 310 kilometers per hour, 6km/h more than the other car. When it comes to fuel economy an obvious choice would be the German car, averaging around 9.9 liters of fuel per 100 kilometers (29 mpg), in combined cycle. That's 25% difference compared to the Japanese car!
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 Japanese car offers significantly better overall protection, taking the lead here. It all continues in the same 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... No mistake, whatever you decide here, but I'd still go for the Porsche. 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™, among thousands of similar, yet so different vehicles.
