GaToRr ?
Exocet ?

"Exocet" is awesome!!!
Much better, than the dumb I thought of, "bwitched" (or shorter version) coz they guys will be stunned as they see a Z chick drive by.
Or what about "Demon", "Diable", "Alchemy", "Semtex", "rictor" as in off the rictor scale, or "Seismic", "quake". Those are naff I'll think of more.
Pity it's not a white one, then you could have "Noise" or "Noiz", as in white noise.
My Z has a cool nickname, that it will be plated out with very soon. Not let the cat out of the bag yet.
