Who would pay if GM came up with some kind of conversion kit to allow your Lade to get 25 or 30 mpg? BTW, does anyone believe such a thing could be possible. I know that thing can getbetter gas mileage. lol
My 600 hp Z06 got 30 mpg on the highway, of course that was because it had 2 overdrives. My Escalade with the computer reprogrammed gets 18-19 on the highway, which I am very happy with for the size of the truck. So it would depend on the cost.
