Cummins-Peterbilt SuperTruck hits 10.7 MPG in latest trial

摘要

Cummins Inc and Peterbilt Motors Co, a division of PACCAR, announced February 18 that the latest version of their SuperTruck demonstration tractor-trailer achieved 10.7 mpg last month under real-world driving conditions. The vehicle was on display the same day President Barack Obama announced a new push to boost medium- and heavy-duty truck fuel economy. Developing a truck that could meet or exceed 10 mpg when fully loaded was considered unlikely, if not impossible, just a few years back, with most trucks averaging between 5.5 and 6.5 mpg, according to Cummins officials. However, with advances in engines, aerodynamics, and more, SuperTruck has proven that 10 mpg is attainable.
