“The school buses that transport visitors into Denali National Park and Preserve each summer could be on the way out. While the diesel buses are charming in an old-fashioned way, there is nothing pretty about them when thinking green and looking under the hood. With that in mind, the park is testing a new hybrid bus that promises to run cleaner and cheaper. The 230-horse power hybrid bus — white and sporting scenic views of Denali on its sides — went on a drive in the park Thursday. The plan is to test the hybrid this summer to determine its potential for replacing the park’s 110 diesel buses. Park managers do not allow visitors to drive cars the length of the park road.” (07/21/08)
