Mr. Sanchez (EPA) gave an overview of the current EPA activities. He emphasized that transmissions are becoming more important in the evaluation of hybrid vehicles. A post-transmission powerpack method therefore is suitable test method. He indicated that EPA will give their input to the HDH drafting group. EPA is willing to test within their internal programs the WHVC with slopes, but powerpack validation will likely be used instead of chassis dyno validation. |
