I love my '09 A8 but want to do my part with the environment by trading for an '07 W12. Yes that sounds backwards but it isn't. The W12 engine converts nicely to LPG. I've tried to convince advisors the Ontario Environment Minister that this is a great time (given the quality of the new technologies) for them to incentivize and encourage drivers to create their own Hybrids. It's been an uphill battle as their tunnel vision is clearly toward an electric future. That's cool but I think there's a demand for efforts we can make now and from what I've learned, Propane is a great alternative.
My eventual goal is to have my W12 converted. In the meantime, would like to hear from any of you who have any insight to this process before I head down the Isle and Marry this sweetheart!
