Peterbilt
Based off of the
company’s Model 579
design, Peterbilt introduced
the UltraLoft
80” integral on-highway
cab and sleeper
design earlier this
year.
Peterbilt is a division
of Paccar.
A subsequent result
of the SuperTruck
One program, the
introduction of the
EPIQ package
available to spec
on all Peterbilt 579
models – including
the UltraLoft – provides
features such
as better aerodynamics,
predictive
cruise control and
a more efficient
integrated Paccar
powertrain.
Spec’d on the 579
UltraLoft, the EPIQ
package provides 2
percent improvement
on aerodynamics and
1 percent better fuel
economy than the
company’s discrete
sleeper models.
For the vocational
market, Peterbilt
remains committed
to clean energy with
the discussion on
an all-electric refuse
truck. The Model 520
all-electric provides
an 80-mile range on
one six-hour charge,
with 400 hp electric
motor and four battery
modules with
315 kWH capacity.
Peterbilt is currently
testing 16 trucks in LA
County.
Also with regards to
vocational applications
on traditional
models, Peterbilt
vocational trucks now
have the option of
spec’ing the Paccar
20,000-lb and 22,000-
lb standard track
version steer axles.

Kenworth
Kenworth, a Paccar company, continues its focus with
the on-highway T680 and vocational T880, with an
emphasis on the rollout of the Paccar 12-speed automated
transmission.
“In 2017, approximately 70 percent of our line haul customers
purchased automated transmissions, up from
about 30 percent in 2013,” Kurt Swihart, Kenworth
marketing director, says. “We received a very positive
response from fleets involved during the Paccar transmission’s
testing and validation program.”
In terms of axle lineup, Kenworth now offers front
axles with standard track options of 20,000-lb and
22,800-lb, ideally suited for the Kenworth T880 and
other Kenworth Class 8 vocational models.
Entering into the alternative fuels market, Kenworth
also recently introduced two cargo transport vehicles:
the T680 HECT (Hybrid Electric Cargo Transport) tractor,
introduced at ACT Expo 2018, and the T680 ZECT
tractor introduced at the 2018 Consumer Electronics
Show. The T680 ZECT runs on a hydrogen fuel cell. It
works by combining compressed hydrogen
gas and air to produce electricity.
Mack Trucks
Mack Trucks began production
of its Mack Anthem, designed
specifically for on-highway
use. Several configurations are
available including a day cab,
48” flat top sleeper and 70”
stand-up sleeper.
Constructed of only three pieces
each, the Anthem features a
redesigned hood and bumper
to improve aerodynamics and
aid in decreased service time
or pre-trip inspections.
The Mack Anthem comes
standard with the 2017 MP
series engine. Fleets can opt
for the 13L Mack MP8 engine,
providing 505 hp and 1,860
lb-ft of torque, or the 11L Mack
MP7 engine, with up to 425
hp and 1,560 lb-ft of torque.
An optional SuperEconodyne
downspeeding package is available
for both engines.
The 12-speed mDRIVE automated
manual transmission
comes standard. An optional
13-speed or 14-speed mDRIVE
HD with low-ratio creeper gears
is also available for applications
requiring more frequent shifting
or heavier loads.
Both engines feature serviceability
enhancements, like a
two-piece valve cover, shimless
rockers and low-pressure fuel
system with an integrated
aftertreatment dosing module.
In addition, an updated
double-walled EGR flow sensor
helps with reducing cold
weather condensation and
soot buildup. A new intake
throttle also enables faster
warmups at engine ignition.
Mack Trucks added Over the
Air remote diagnostics and
programming capabilities to its
Mack Connect software suite.
Other functionality already
available with Mack Connect
includes the Mack GuardDog
Connect telematics and Mack
ASIST service management
system. For all Mack Trucks
featuring 2017 or newer
engines, the Over the Air
remote software functionality
provides fleets the ability to
update powertrain components
and vehicle parameters.

Rainier Truck and Chassis
Particularly due to the recent boom
in e-commerce deliveries, Gary Jones,
president of Rainier Truck and Chassis
predicts an upswing in Class 7/8
cabovers for intercity delivery applications,
where a conventional truck has
trouble maneuvering.
Branching into the heavy duty market,
Rainier has added a Class 7 version to
its lineup. The company also updated
the exterior look of all truck models
beginning with 2018 production.
“All Rainier cab-over-engine truck
models share a rugged and reliable
common chassis-cab platform,” Jones
says. “This was intentional to help
dealers and customers keep the overall
cost of doing business down.”
Intended for delivery, service and
refuse applications, Rainier vehicles
come standard with the following:
• Cummins B 6.7L turbo-charged
diesel engine, with 300hp
and 660 lb-ft of torque
• Allison 2500RDS 6-speed
automatic transmission with
push-button shift selector
• 12V electrical system
• Air brakes with auto slack adjusters
• Four-wheel, four-sensor ABS
with traction control
• Air ride driver and passenger
side seats
• LED high/low beam headlamps,
clearance and marker lamps
• Heated air dryer, heated remote
fuel filter and heated moisture
ejectors for air tanks
Fleets have a choice of load leveling
air ride for front and rear suspensions
or leaf, with no up charge, and
a choice of any wheel base with no
up charge.
