Chevrolet’s new Corvette Z06 halo car will officially debut tomorrow during the Detroit Auto Show, but more information about the car is leaking ahead of its ceremonial introduction.

If leaked information that showed up on Hot Rod magazine’s website is correct, the car has a beastly 620 hp and 635 lb-ft of torque sent through an eight-speed automatic. Yes, the Z06 will be offered with both a seven-speed stick and an eight-speed auto.

It is also supposed to have the same wheel and tire sized as the old ZR1. The torque tube is made of carbon fiber, although that’s sure to be one of many parts made of the same material.

Finally, it sounds like the car is going to be offered with three trim levels with increasing levels of aerodynamic performance. The top-trim version will be called the Z07. Everything will come out tomorrow at 10 a.m. when Chevrolet holds its press conference when there’s sure to be more exciting details on tap.
