This Mysterious Nismo 370Z Will Be Unveiled Tomorrow

The Nissan 370Z Nismo is already the Z to have, thanks to a bump up to 350 horsepower and a host of other performance enhancements. That may not be the case anymore after tomorrow, depending on the secret Nissan has in store for us.

Nissan just announced on Twitter that "a special global Nismo debut" will take place tomorrow afternoon at 1 p.m. ET in North Carolina. They offer this picture with it, but sadly no other clues as to what it is. Clearly, it's some kind of Z, but we don't know if it's a new special edition or just a concept.

Nissan PR guy Dan Bedore says this debut will happen at ZDayZ, a big annual Z event at Fontana Village Resort.

Okay, this one kind of caught us by surprise. Any guesses or clues what it might be?
