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 560hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 550hp engine designed by Nissan.

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, still it doesn't help us solve our dilemma, does it? On the other hand, if we'd like to consider vehicle mass in this context too, which we definitely should, the Japanese car offers a marginal difference of 8% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Nissan is significantly less fault-prone, all the models observed together. That's the official data, while our visitors describe reliability of Porsche with an average rating of 3.9, and models under the Nissan badge with 4.3 out of 5. Some independent research have also placed 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.

Nissan is a bit more agile, reaching 100km/h in 0.4 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 315 kilometers per hour, 3km/h less than the other car. When it comes to fuel economy an obvious choice would be the German car, averaging around 9.7 liters of fuel per 100 kilometers (29 mpg), in combined cycle. That's 22% difference compared to the Japanese car!

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 slightly better overall protection and takes the lead. When it comes to performance, both vehicles provide similar experience, so I wouldn't point any of them out. the German car is in a different dimension economy-wise, and many people will find that crucial. It's not difficult to say then that if I'd need to make a choice, it would definitely be 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™, out of 12.000+ vehicles we currently have in our database.
