Robert - great poll question!

I suspect: never. That's it, as far as high-efficiency internal combustion autos go, at least for the North American market.

(Assuming plug-in hybrids don't count.)

And as an aside, I don't buy the statement that crash protection necessarily means weight gains.

EDIT: both Mazda and Ford have publicly stated several times that they aim to trim a serious amount of weight from their vehicles - on the order of 10+%. Are their cars going to be 10% less safe? I don't think so.
