Once only passable by foot or horseback, Yosemite National Park now allows visitors to enjoy the pristine surroundings onboard new low-emissions, fuel-friendly vehicles powered by Eaton’s hybrid electric systems. Eaton worked with the U.S. General Services Administration and Delaware North Companies Parks and Resorts, which handles the majority of the park’s transportation needs, to deliver four Class 8 tractors fitted with the Eaton systems.

“We are definitely realizing fuel consumption reductions, currently averaging about 6.7 mpg with the tram tractors,” said Dan Anthonijsz, village garage manager at Yosemite. “That’s a huge improvement over the 1 mpg that we were getting with the propane trucks that the new vehicles replaced.”
