2013 L99, the Range costs me about 2-3 mpg.
It is worth it to me. On highway driving I can remove the Range and increase my mpg's by the 2-3 referenced above.
I agree with the posters saying it works, as I said in another post, I find it hard to believe GM put the technology in the car, at an extra cost, for no reason.
I believe I read somewhere that it is supposed to give a 10 percent increase in FE.
The Range gives me the option, and is worth it.
