I always love watching these videos from Hawaii, because they make me feel warm just watching the drive in the sunshine (it's wet and cold in London). On a serious note, I've done a similar amount of miles in my Prius to you, and despite having 15 inch tyres and driving in Eco mode, the odo is showing the equivalent of 49 mpg US. That's way lower than your 72.9mpg. I suspect the big factor is the difference in temperature between England and Hawaii during the winter.
absolutely. although, with a gasser running the engine full time, the drop off in the cold is probably less.
Just winding down some after a whirlwind user conference and compressed training sessions. I guess I was in a Looney Tunes mood.
