Volvo's European HQ is doing the same with a Cabover
Volvo fuel saving Concept( Cabover)
Mercedes is doing the same, do not know if their division Freightliner has a development?

I got 2mpg going up Jellico last year . ouch

Personally, I think the mpg results by a semi mfr are flawed as all the tests seem to be done on flat roads. Test them along I-81 thru VI, PA & NY. Hills out west. Headwinds and crosswinds. Then see what they claim.

Is this technology going to be shared with other truck manufacturers since they received 20 million dollars of tax payer money? "The US Department of Energy gave Volvo $20 million to work with and the truck maker matched the funding, and then some.". That is a huge fuel savings the best I ever seen in a Volvo was 8 pulling 38,000# on flat roads.

Thermal efficiency and aerodynamics are huge improvements!

My company just bought a new rig but I've heard it only gets 9mpg when one of our machines is on the back.
