Daycab configurations for Peterbilt Model 579 EPIQ

Peterbilt Motors Company (www.peterbilt.com) has introduced a daycab version of its aerodynamic, fuel-efficient Model 579 EPIQ sleeper tractor.

“Fleets wanting to operate fuel-efficient daycabs have been an underserved market,” said Robert Woodall, Peterbilt assistant general manager, sales and marketing, during the model’s unveiling at the 2016 ATA Management Conference & Exhibition in Las Vegas. “Its comprehensive, optimized aerodynamic package, fuel-efficient powertrain and other technologies can provide customers up to 14 percent improved fuel economy. 

“It is ideal for fuel-conscious day-cab fleet customers in regional, tanker and bulk haul applications, helping lower operating costs and bringing new levels of productivity, uptime and driver satisfaction.” 

Enhancements

Among the aerodynamic enhancements on the Model 579 EPIQ daycab:

• Multi-piece aerodynamic hood available in both 117” and 123” lengths.
• Three-piece collapsible roof fairing. (An industry-unique design that in a few minutes allows the roof fairing to be lowered, allowing the truck to be transported without the need to completely remove the roof fairing, as is common with most daycabs.)
• Chassis fairings with rubber skirts from the quarter fender to the back of the cab and aerodynamic rubber closeouts under the sides of the cab.
• Three-piece aerodynamic bumper.
• Bumper air dam and bumper-to-hood seals. 
• Front wheel closeouts and fender liners.
• Chassis fairing kickouts.

Paccar engines

The Peterbilt Model 579 EPIQ daycab is available with the recently improved, fuel-efficient Paccar MX-13 or MX-11 engine in a wide range of horsepower and torque ratings, Woodall said. 

“Fuel efficiency is further enhanced with the Paccar MX engine paired with the Fuller Advantage automated transmission. This powertrain features precise communication and proprietary control logic between the engine and transmission.”

Other features of the Model 579 EPIQ package include low rolling resistance tires, the SmarTire Tire Pressure Monitoring System and a single horizontal exhaust configuration.
