Navistar Statement on Final GHG/Fuel Efficiency Regulations from EPA and NHTSA

WARRENVILLE, IL--August 9, 2011: Following is a statement from Daniel C. Ustian, Navistar chairman, president and chief executive officer, about the recent announcement of final Greenhouse Gas (GHG) and fuel efficiency regulations for commercial vehicles:

“With this rule, EPA and NHTSA have now set an example for what could be a worldwide GHG and fuel efficiency regulation for heavy duty trucks and engines.”

“Navistar commends the Environmental Protection Agency (EPA) and the National Highway Traffic Safety Administration (NHTSA) for developing one single, national standard for GHG and fuel efficiency for medium- and heavy-duty engines and trucks. We were pleased to be part of the process providing the agencies with information on the positive impact of total vehicle technology integration on fuel efficiency and GHG emissions.”

“As a fuel-efficiency leader, Navistar is always focused on delivering value to our customers, and we currently have plans in place to continue to support this competitive position by delivering integrated truck and engine technology solutions that achieve maximum fuel economy for our customers. We feel this customer-focused approach aligns Navistar with the intent of the new proposed GHG rule.
