Why are we funding light duty hybrid before heavy duty?
“The only heavy-duty hybrid truck funding available since 2007 has been used to conduct in-use and laboratory evaluations on hybrid vehicles, mostly delivery trucks and transit bus applications. None of this funding was for hybrid R&D. Since 2007, the $1 million to $1.5 million per year for heavy-duty R&D has been focused on aerodynamics, thermal management, and friction and wear reduction. Although there were no congressional requests for FY 2007 through FY 2010 that specifically targeted 21CTP heavy-duty hybrids, the work cited above was completed under the DOE’s Office of Vehicle Technologies, which has included both light-duty and heavy-duty advanced vehicle testing and R&D activities, with some of these being hybrid-specific. Project funding since 2007 is shown in Table 4-2.”
