Peterbilt unveils its Model 579 UltraLoft improving driver comfort, fuel efficiency


Peterbilt Motors Co. introduced the new Model 579 UltraLofta new integral cab and sleeper design for Peterbilt’s on-highway Model 579. The driver experience was the key factor in designing the new UltraLoft, the manufacturer noted. By optimizing the space available, the new sleeper model includes a massive amount of storage and Peterbilt line-up leading comfort. The UltraLoft gives drivers ultra wide upper and lower bunk mattresses, impressive headroom in both bunks and some creature comforts of home with space to accommodate a large microwave and enough room to fit a 32 in. flat screen TV.

“The UltraLoft was designed and tested in close collaboration with customers and drivers,” said Kyle Quinn, Peterbilt Motors Co. general manager and PACCAR senior vice president.

The improvements are not limited to the driver experience. The UltraLoft provides an estimated 2% aerodynamic improvement, compared to the Model 579 discreet sleeper.

Plenty of room to stretch out.

“Throughout the design process we asked ourselves, what is best for the drivers to be the most comfortable and productive? So, we added headroom, storage and improved the overall space to maximize the driver’s experience,” said Scott Newhouse, chief engineer with Peterbilt Motors Co. “The expansive loft style space, the increase in efficiency and the reduction in overall tractor weight are a testament to the team’s focus on maximizing the driver experience.”

The 579 UltraLoft is available for order now and production scheduled to begin in the summer. Stay tuned to Fleet Equipment for an in-depth conversation with the Peterbilt team that brought the UltraLoft to life.
