Kenworth SuperTruck 2

We Saved The World's Best For Last

Kenworth invented the aero truck with the T600 and the trend continues to the most aerodynamic production truck yet, the T680. The SuperTruck 2 was developed over a 6-year period as part of a collaboration with the Department of Energy’s (DOE) SuperTruck program, designed to challenge truck makers with improving freight efficiency using a diesel engine as the main power source.
