While money spent in fuel is not important for (wealthy) Ferrari, Lamborghini and McLaren owners I think there's some media pressure as not to portray their companies as environmentally insensitive or something.
Therefore we got Ferrari, McLaren, Porsche hybrid supercars.
Will flexi-fuel (ethanol) sports cars follow?
I heard that current ethanol-gasoline fuel mixture sensors aren't accurate enough to be used in hi-power cars. Is it true?
Will such an incorrect fuel air mixture lead to nasty polluting, backfiring, or even engine damage when demanding high power from them?
