A few months ago, we wrote about the public-private partnership between the U.S. Department of Energy and Class 8 truck makers to create concepts called SuperTrucks. The four manufacturers involved designed lighter, more aerodynamic, and more fuel-frugal trucks to hit escalating freight efficiency targets in each phase of the program. Daimler, Navistar, Peterbilt, and Volvo spent the past 18 months showing the results of the SuperTruck 2 phase while work gets going on SuperTruck 3. This month, Volvo becomes the first of that group to debut an all-new truck incorporating lessons learned in the SuperTruck program. Starting with a clean sheet of paper, the new Volvo VNL is said to be as much as 10% more fuel efficient than before, a stat to get fleet managers and owner-operators to pay attention.
