I saw this over at AutoSpies.com (that saw it at 4wheelsblog.com), horrible writing and horrible technical details, but other then that the car is pretty cool.
Geigercars, the well-known German tuning company unveiled its latest masterpiece: the Corvette Black Edition Z06. What is so different about this Corvette? Well, the LS7 7.0-liter V8 engine has been modified and is now capable of developing 592hp. A good improvement if we look that the “standard” Z06 develops 512hp (TDC Note: Or rather, 505hp…). Not at last, the car come with 19″ black wheels in order to provide better hadling at high speeds (TDC Note: Black wheels provide better handling apparently). According to the manufacturer the vehicle can easily achieve 300+ km/h while the sprint from 0-100 km/h is made under 5 seconds (TDC Note: I hope so considering that a stock Z06 does it in 3.4 seconds).
