Peterbilt Motors introduced enhancements to its Model 579 EPIQ that it says can improve fuel efficiency up to 14 percent. The company also announced new models or expanded versions of existing models, including improvements in its natural gas-powered offerings.
The 579 EPIQ’s fuel gains come from aerodynamics, drivetrain, tire pressure monitoring and automatically generated driver performance tips, said Chief Engineer Scott Newhouse during the during the Mid-America Trucking Show. He detailed some key elements:
“The Model 579 is the most aerodynamic truck in Peterbilt’s 75-year history and when configured with the EPIQ package, it takes fuel economy to even greater levels,” said Darrin Siver, Peterbilt General Manager.
Peterbilt introduced a new 58-inch sleeper for its Model 579 in low- and mid-roof configurations, which it says is ideal for weight conscious short- and regional-haul operations.
The new sleeper, which goes into production during the fourth quarter, reduces weight by up to 100 pounds (versus the 80-inch sleeper) while including all of the amenities found on Peterbilt’s larger sleepers.
The new sleeper includes a full-length door to help facilitate loading personal gear and belongings. Full-length, integrated extenders to minimize trailer gap and improve aerodynamic efficiency. Other features include a television mount, refrigerator and microwave shelf.
