The GTR performance argument is getting old. There are many factors that go into the decision making process when you purchase a new vehicle. 'Enthusiasts' would consider track performance and 0-60 times etc as one of those variables. But I stress ONE of those variables. It is silly to think that the consumer (even a sports car enthusiast) just wants the fastest car.
The flip side is that the auto industry is also not trying to just develop the fastest street legal car. BMW is not and does not want to produce an M3competitive with the GTR. They have no reason to. They are balancing the needs of different consumers to provide a solution that works for a number of individuals with different priorities. Every enthusiast doesn't necessarily want to have the fastest car on the track with major compromises for everyday livability. Not to mention the GTR is so loaded with technical 'helpers' that the driver often becomes detached from the experience.
Based on the fact that you seem to believe everyone is out to produce the fastest car, I guess Nissan needs to go back to the drawing board since the Viper ACR is significantly faster on the track. So Dodge must be light years ahead of Porsche and Nissan
.
This is laughable. Nissan built a very nice fast car at a reasonable price, but it hardly resets the standard for other manufacturers with different goals.
On a side note, if you read most professional reviews of the GTR, it seems the writers would ultimately take a Porsche over a GTR even though it may produce a slower lap - back to the basic concept that achieving the fastest lap isn't the 'end all be all' of a performance car.
