13 mpg semi

Interesting article, thx for posting. Thirteen MPG for a vehicle and load that large is significant. The ability to move a huge mass and a very large weight at highway speeds at that MPG is amazing progress from what I recall from my very limited experience driving much smaller commercial trucks 45 + years ago.

Good article, in that it details the research and development that went into this study. This is one 'study' that actually has practical use.;)
