Peterbilt Model 579 EPIQs Superior Fuel Efficiency Now Available in Day Cab Configurations
Based on the success of the aerodynamic Model 579 EPIQ sleeper truck, Peterbilt has introduced the aerodynamic, fuel efficient Model 579 EPIQ day cab, Peterbilt Motors Company announced during the ATA Management Conference & Exhibition in Las Vegas.
“Fleets wanting to operate fuel-efficient day cabs have been an underserved market, and Peterbilt is pleased to provide the new Model 579 EPIQ day cab,” said Robert Woodall, Peterbilt Assistant General Manager of Sales and Marketing. “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.”
Among the aerodynamic enhancements on the Model 579 EPIQ day cab are:
• Multi-piece aerodynamic hood available in both 117- and 123-inch lengths;
• A three-piece collapsible roof fairing;
• 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;
• A three-piece aerodynamic bumper;
• A bumper air dam and bumper-to-hood seals;
• Front wheel closeouts and fender liners; and
• Chassis fairing kickouts.
Customers can specify the full aero package through Peterbilt dealerships for simplified ordering or customize it for specific needs, such as an aero bumper-to-back-of-cab package or an aero bumper-to-front-tandem package. The aerodynamic components and packages are also available through Peterbilt dealerships for aftermarket installation.
Peterbilt’s Model 579 EPIQ day cab is available with the fuel-efficient PACCAR MX-13 or MX-11 engine in a wide range of horsepower and torque ratings. 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.
The three-piece collapsible roof fairing is an industry-unique design that in a few minutes allows the roof fairing to be lowered. This allows the truck to be transported without the need to completely remove the roof fairing, as is common with most day cabs.
Other features of Peterbilt’s Model 579 EPIQ package include low rolling resistance tires, the SmarTire Tire Pressure Monitoring System and a single horizontal exhaust configuration.
