Peterbilt broke new ground in aerodynamic efficiency and fuel economy
when it introduced its landmark Model 579 in 2012. The new EPIQ package
for the Model 579 provides an optimized combination of technologies and
components that allow customers to easily order and operate the most
fuel efficient Model 579 available, the company announced during the
Mid-America Trucking Show.
“The Model 579 was the result of the largest investment and most
comprehensive development process in Peterbilt’s history. Through an
extensive design and testing process, we were able to achieve new
standards of fuel efficiency, overall performance and a styling and
operating environment that drivers love,” said Peterbilt General Manager
and PACCAR Vice President Darrin Siver.
“We continue to enhance the Model 579, as we do with our entire product
lineup, and the new EPIQ package is the result of improved performance
of key components and creating an optimized spec that utilizes the most
fuel efficient options available for this vehicle. EPIQ is a truly
intelligent choice for greater fuel efficiency.”
According to Landon Sproull, Peterbilt Chief Engineer, the EPIQ package
can improve fuel efficiency of the Model 579 by up to 10 percent. “It
utilizes an enhanced drivetrain – including Peterbilt’s new combination
of the PACCAR MX-13 Engine and Fuller Advantage UltraShift transmission
– all available aerodynamic options and optimized spec’ing through our
proprietary software system used throughout our dealer network,” he said.
The EPIQ package includes:
-
Complete Aerodynamic Package: This feature combines all
fairings and aerodynamically enhanced components available for the
Model 579. The fairings include 18-inch sleeper side extenders with
8-inch rubber flares; full chassis fairings with rubber skirts from
the quarter fender to the front of the tandem axle with rubber
closeouts under the sides of the cab and sleeper; and roof fairings
with an exclusive rear wall closeout. Aerodynamically enhanced
components include a three-piece aero-style bumper; multi-piece
aero-style hood; painted outside sun visor; and an aero-style aluminum
battery box positioned on the passenger side, under the cab.
-
PACCAR MX-13 Engine: “The MX-13 was already an industry leader
in fuel efficiency, performance and reliability, making it the optimum
choice for the EPIQ package,” said Sproull. The MX-13 Engine delivers
improved fuel economy through electronically controlled fuel injection
pumps and high pressure rail technology.
-
Fuller Advantage Automated Transmission: The PACCAR MX-13
Engine is available in a new drivetrain pairing, designated as APEX,
with the Fuller Advantage Automated Transmission that is part of the
EPIQ model. This new combination features precise communication
between the engine and transmission, as well as proprietary control
logic to further enhance fuel economy. “This exclusive collaboration
is developed to deliver fully integrated powertrain performance and
superior fuel efficiency,” said Sproull. APEX is also available on
other Peterbilt products.
-
Single Horizontal Exhaust: To further increase aerodynamic
performance, the EPIQ package recommends a single horizontal exhaust
configuration or a single right-hand back-of-sleeper exhaust
configuration.
-
SmarTire Tire Pressure Monitoring System (TPMS): “Incorrect
tire pressure can play a significant factor in fuel efficiency so EPIQ
includes the TPMS to provide operators with real-time tire pressure
information,” Sproull said. TPMS monitors the pressure and temperature
of each tire and will warn the operator of tire-related problems.
-
Low Rolling Resistance Tires: Another way tires can improve
fuel economy is by minimizing friction between tires and the road. Low
Rolling Resistance Tires are designed to do this and are available on
the Model 579 spec’d with the EPIQ package.
-
Optimized Spec’ing Software: Peterbilt and its dealer network
use a proprietary spec’ing system to optimize vehicle performance and
exactly match customers’ business and application requirements. This
software has been enhanced to complement the Model 579 EPIQ by
recommending the most fuel efficient rear axle ratios and engine
settings, among other options.
