SuperTruck semi achieves 54-percent increase in fuel economy

Cummins and Peterbilt have created a new demonstration tractor trailer that boasts a 54 percent increase in fuel economy over current trucks. This particular Class 8 Peterbilt 587 uses a high-efficiency Cummins ISX15 engine and managed to average 9.9 miles per gallon over 11 runs over the 312-mile route between Fort Worth and Vernon, TX with a gross combined weight of 65,000 pounds. For comparison's sake, most modern trucks manage between 5.5 and 6.5 mpg. For most long-haul truck drivers, an increase in fuel economy of 54 percent would equate to a savings of around $25,000 per year at current diesel prices.

The SuperTruck uses light-weight materials, an efficient engine and aerodynamic improvements to net its fuel economy increase. Peterbilt also worked with Eaton to develop a special driveline with fewer parasitic losses and better gearing, and the truck manufacturer says many of the features demonstrated on this particular truck may show up on production models in the near future.

good job but they couldn't make the front of the cab more aerodynamic? looks like the exact same cab to me with covers on the drive wheels.

10 mpg hauling 65,000 pounds is pretty damned impressive!

lot of aerodynamic work on the truck, covering the rear tires, trailer skirts, and the boat tail thing at the rear of the trailer

not compared to a train.

i'm still amazed we don't move more by train than truck.

Some actually have large plastic sheets for lack of a better word. that or its a hard vinyl. Either way they act as covers. Lots of them bring over our BMWs and MIni's that way. Our Lexus, Acura and Infiniti's come on a standard open air carrier

Peterbilt was doing 11mpg back in 1988 with a trick 372 cabover rig.

SteVTEC

468 mpg per ton for the CSX
This truck is doing 9.9 mpg with 32.5 tons = 322 mpg per ton

Something like that?
