Earth Day Texas:10.7 mpg Peterbilt
Chris Roseberry of the North Texas Renewable Energy Group got to see this rig in Dallas.He had slides but there were so many questions today at their meeting that we never made it that far on the PowerPoint presentation.
The rig sounds interesting,although nothing like the Bullet Truck.Here's a link

Base line was likely 6 to 8 mpg.

interesting.. numbers.. is that hauling at capacity load or "dead heading"? either way 10.7 at minimum wieght is impressive as hell. Apparently it is realworld testing...80,000 lbs.
Maybe it needs a trip from New York to Anchorage via Sacramento, according to google it is only a 600 gallon trip @ 10.7 mpg with 50 gallons to spare.
Imagine how far those little 6 or 8 bolt trucks that people drive as urban warrior cummuters could get, if they utilized some of that technology in the 150's, Rams, and Sierra's.
I am impressed.

I do wonder why those rear tires aren't enclosed. Of course there is the risk of building up snow, but a simple cover with a few exterior screws would be easy to take on and off. Impressive return.

Sure there is still room for improvements on both the aerodynamic and weight reduction, but I still don't see an owner-operator really willing to pay the difference on the initial purchase cost of a new rig.

Owner-ops haven't embraced any mods around here. It'll be the company trucks, then trickle into the owner-ops second hand.
Interesting use of a splitter w/ high clearance.

What is the lifespan of and average long hauler 1 million to 2 plus miles.
That is a cost savings of 73 thousand gallons plus. I am sure the price different between a new ECO truck and your standard fuel pig could not be that big????? nearly 400 thousand dollars on the first million miles up here and Canada land.

And the ever-increasing costs of petroleum-derived fuels may also increase the savings from the efficiency improvements.
