This is a supercar.
This is not.
Let's review why.
Supercar:
A supercar is usually defined by more than performance. It is defined by price, power, rarity, & build quality on the usual basis. You could even consider the customer service on a long end. But a supercar includes all of these.
Price:
Your typical supercar sells for over $250,000-$275,000 these days. There are many cars beyond this point new, but price does not define the category alone.
Power:
Supercars perform at a level beyond most. 600Bhp has now become the new standard in the current. These cars are usually at the top of leaderboards as well. But like before, power & times alone do not define.
Rarity:
If there is 1 thing a supercar has, it's rarity. Although this does heavily depend on location, take note of how many examples are made of said supercar per year which is typically under 1,000. Look at today's current, or just slightly older supercars.
1,270 Carrera GT's = 635 cars per year.
3,500 total SLR's = 835 per year if it stopped now. However, there are not 3,500 SLR's built.
Murcielago 6.2 = 400 units per year leading to 1,600.
Murcielago 6.5 = 350 units per year leading to 700. A little higher though.
Enzo = 400 produced.
Zonda F = 25 produced according to factory.
Koenigsegg CCR = Under 50 units per year.
Veyron = 300 expected.
Notice how rarity is a huge similarity between supercars.
Build Quality
Yes, build quality is something in all supercars. Look at a 911 Carrera, and then look at a Carrera GT. The CGT just has so much more time invested in its building process. These supercars are built to the highest degree. Even if companies such as Ferrari & Porsche do it for all their models, you notice it's still higher in the Enzo or CGT. These cars are hand built, and put into conditions that push the car in every way. These cars are tested in the factory, out on the track, and back in the factory. If the car doesn't meet a standard though, it's back to see why. These cars are built this way to make sure you get your $300,000 worth. Having a car just do a break-ins means nothing as every manufacturer will do this for certain cars. It's to generally make sure they work properly. Supercars just go another level.
There is a reason is a supercar is a supercar. You have to look at the things all supercars share. You can't just have a car be equal in price, and claim it's a supercar. You can't just have the car be built in numbers of 20 limited editions. And you certainly can't just have a car set an equal lap time, and call it a supercar. A supercar hits all of these and more. Want proof? Go look at an Enzo or a Zonda. Notice how both cars have the same traits, not just 1 or 2.
Yes, there are many cars that could be questionably called supercars such as the Ultima or the SSC, and yes, I've also let out other traits such as presence.
The point is though, the GT-R is
not a supercar, and never will be. Supercars are a class of their own. They all have certain traits that make them that. The only thing a GT-R has in common is a performance time. It still does not have build time, rarity or presence any of the cars I listed above have.
If the GT-R is a supercar, it is a
Japanese supercar. Outside of Japan though, it's nothing more than a high-performance sports car.
