Super charged. Fuel ecomony. Are you on drugs.
I've driven a few super charged range rovers & after the initial £10 worth of fuel to start the fecker you can watch the fuel gauge moving as you drive.
Actually, I am on drugs, for pain, but they haven't impacted my ability for recall and I don't recall mentioning anything about fuel economy
My brother in laws RR drinks it up and he's proud of the fact he can do 8mpg.
I drove it once, the time my son said "Uncle Mark, my daddy is a better driver than you!"
I got it up to 13mpg in just a few miles.... He drove a bit more conservatively after that, well, until he dropped us off at least
