There are no rivalries quite as vicious as the one between the
Nissan GT-R and
Porsche 911. The two are constantly playing a revolving game of one-upmanship with constant revisions and updates, each aimed at staying at the top of their game - and ahead of the other. The battle typically takes place on the
Nurburgring, that most vaunted of circuits that is Porsche's back yard and where
Nissan has set up shop. But of course it's not only street-legal supercars that battle it out at the
Green Hell.
