New ‘Super Truck’ Promises Huge Fuel Savings for Big Rigs

Peterbilt and Cummins have successfully demonstrated a tractor-trailer that gets just under 10 mpg under real-world conditions.

A single-digit fuel economy rating doesn’t sound like much to brag about, but in the world of tractor-trailers, it’s a massive improvement over the status quo. In fact, it’s a full 54 percent increase in fuel economy over the average tractor-trailer on the road today. The corresponding fuel savings could save owners around $25,000 in diesel costs a year, and would reduce annual greenhouse emissions by 35 percent per truck.
