Very cool technology and not all that complicated.
I dont think any vettes had VVT besides the LT5... I think only some SUV's got them, along with the new camaro with the L99 (VVT version of the LS3)
Does the corvette need it? Probably not. The Z06 already gets close to 30 MPG with 505 HP and no VVT.
