It’s been rumored for some time and now we can finally confirm that the first Nissan GT-R
Nismo prototype has begun testing. The news comes to us from Autocar which, speaking with Nissan
exec Andy Palmer, not only clarified the existence of the prototype but also that the GT-R Nismo will be "the fastest GT-R ever." No other technical details were given but Palmer did reveal that "the majority of the exterior changes are aero and downforce related."
