It's almost 40 years since the first Australian Kenworth rolled
off the Melbourne production line on the second of March, 1971 - a
defining moment for Kenworth and the future of the Australian road
transport industry.
Four decades on, Kenworth is still leading the way; defining
tomorrow - as only Kenworth can - with the launch of the exciting
new 2011 range.
Driven by a continuous innovation and product development
process , and also by customer and driver feedback, Kenworth has
redesigned the entire model line up, starting with the T359 to the
T609 and flagship K200.
Each model is packed with new features and benefits. In line
with forthcoming regulatory changes on engine emissions from
January 1st 2011, the new range also fully complies with ADR 80/03,
following a major project to integrate and optimise solutions for
Australian customers and applications.
"The 2011 Kenworth range proves yet again Kenworth's ability to
develop and deliver trucks that best fit Australian applications,
meeting or exceeding the needs of our customers with versatile,
reliable and most of all productive solutions," said Andrew
Hadjikakou, Director Sales and Marketing for PACCAR Australia.
PLANNING AND DEVELOPMENT
As Andrew explains, "Preparations for the new range commenced
well over two years ago - effectively as soon as the launch of the
2008 range was completed. Whilst the need to change for 2011 was
initially driven by new emission standards, it also allowed us to
further refine and enhance many other aspects of the range in line
with our own research and development, and feedback from our broad
customer base"
"We have consulted widely with our customers and involved them
in our test program to ensure that the new range continues to meet
their needs and applications in our dynamic road transport
environment ", Andrew continued.
TESTING
By the end of this year Kenworth will have concluded the
construction and deployment of over 30 test vehicles, and millions
of kilometres of road testing in some of Australia's harshest
conditions and applications.
Of paramount importance in delivering the new range was the need
to maintain the outstanding performance, quality, durability and
productivity for which Kenworth is renowned. Local testing of the
technology used to meet the new standards, to supplement the US EPA
07 experience gained elsewhere in the PACCAR group over the past
three years, was a critical part of the mix.
In combination with all the technical testing, the knowledge
gained from this real life experience in the Australian environment
will deliver the best range of 2011 compliant heavy-duty trucks
available.
FEATURES AND BENEFITS
The 2011 Kenworth range features a wide range of important
enhancements - from new generation exterior styling and cooling
system advances, to significant driver environment improvements,
additional safety features and a host of key mechanical
improvements.
Every truck across the Kenworth range now also meets the target
emissions performance ratings for ADR 80/03.
New Exterior Styling
Let's start with the most obvious changes...the exterior
styling.
The athletic stance and sweeping aerodynamics of the new aero
conventional models are striking...head turning for all the right
reasons.
Like all Kenworths, everything begins with the grille. A grille
that's now bigger, bolder and from which Kenworth's design DNA now
flows more freely around a wider, more contoured engine
compartment, more muscular wheel arches and more streamlined side
fairings.
Completing the picture...the new aero models also feature more
efficient, streamlined side air intakes, new swept back headlights
and new tapered, FUPS compliant bumpers
Increased cooling efficiency and
performance
For the aerodynamic models T609, T409 and T403, the FUPS bumper
now has design elements to improve the air flow to the radiator.
These models also have a new air intake system with improved seals
designed to improve cooling efficiency by delivering cold ambient
air flow to the engine for optimal engine performance.
The new cabover features a completely revised cooling package for
even better cooling performance in Australia's harsh
conditions.
Upgraded HVAC
The Delphi Heater, Ventilation and Air Conditioner unit, already
a proven performer in the cabover, has now been added across the
conventional range. The Delphi unit provides improved efficiency
and air flow and a better in-cab operating environment - keeping
drivers and passengers warmer in winter and cooler in summer. An
integrated serviceable filtration system helps provide a dust free
cab environment.
Improved cabin appointments and
ergonomics
New doors have been introduced with standard electric windows
across the entire range. The new doors also provide improved door
handles and central locking for greater operating ease. The
standard keys have been upgraded in heavy duty steel for enhanced
durability. There are wider padded arm rests with integrated window
and mirror controls for increased comfort and convenience.
Mechanical improvements
The aerodynamic models also feature a new Hood Tilt Assist so
operators can gain far easier hood access for those all-important
daily checks. For greater durability, rear hood supports have now
been fitted directly to the chassis rails independently of the
cab.
Enhanced safety
At Kenworth, safety has always been a paramount consideration,
and we continue to invest heavily in developing a safer working
environment for road transport operators and other road users.
The 2011 range reflects this commitment, and all new models will
be available with the latest Kenworth EBSS Safety Package.
Designed to provide a class leading and reliable system for
Australasia's unique road conditions and applications, EBSS
incorporates a variety of safety features including ABS, Drag
Torque Control, Traction Control and ESP.
In addition, alloy Front Underrun Protection System (FUPS)
bumpers are now standard across the range, and include provision
for optional driving lights.
New automated transmissions
The 2011 range also sees the introduction of the new Eaton
"Ultrashift plus" automated transmissions.
Yet another way Kenworth is defining tomorrow, this two-pedal
transmission delivers significant improvements in performance,
superior acceleration and low speed manoeuvrability, along with the
following benefits:
- A revolutionary new clutch technology called ECA (Electric
Clutch Actuation) and intelligent shift selection software to
ensure trucks have maximum performance and efficiency, regardless
of the operating environment.
- Grade sensing, weight computation, and driver throttle commands
to make intelligent launch and shift decisions for reliability and
performance.
- Hill Start Aid, to ensure trucks can safely launch on a grade
without fear of rolling back.
ADR 80/03
Depending upon the engine specified, ADR 80/03 compliance is
achieved either by:
- Cooled Exhaust Gas Recirculation (EGR) with a Diesel Particulate
Filter (DPF), where the engine and after treatment perform as a
system to meet ADR80/03; or
- Selective Catalytic Reduction (SCR)
Kenworth's application engineering process has delivered
optimised solutions to integrate both EGR and SCR as required,
seamlessly across our engine range. So as well as being highly
efficient and low maintenance, for the Kenworth range, both cooled
EGR with DPF and SCR have little or no impact on payload and
efficiency. Kenworth customers get the emission compliance they
need with the proven performance and reliability of engines they
know and trust - all with the back up of our renowned local design
and manufacturing capability and Australia wide support network.
See appendix 1 for more detail on EGR with DPF and SCR emission
solutions.
MODEL LINE UP
T609 - Australia's Premium bonneted prime
mover:
The T609 reflects almost 25 years experience of aerodynamic
truck design in Australia starting with the groundbreaking T600.
Incorporating award winning design elements, it delivers
outstanding aerodynamic performance, with eye catching new
styling.
The bolder grille is now lower, allowing air to flow more freely
around a wider, more contoured engine compartment. Completing the
picture are more muscular wheel arches and streamlined side
fairings.
The new model also features more efficient, streamlined side air
intakes, new swept back headlights with chrome surrounds and new
tapered FUPS compliant bumpers. There is a great range of
contemporary trim colours including Crimson and all new colours in
Charcoal, Cedar, Eucalyptus, Shiraz and Wheat. The cab is quieter
with enhanced noise and heat shielding and there is.a wider landing
step for better visibility on exiting the cab.
Primarily suited to on-highway applications the T609 offers a
range of engines up to 615 peak hp, improved cooling efficiency and
state of the art interior appointments. The T609 provides the power
to haul the biggest payloads, efficiently and in comfort, and is
well suited to multiple trailer combinations. For outright
versatility and road presence in an aerodynamic package, there is
no finer truck than the T609.
The T609 ADR 80/03 engine options include Cummins ISX and
Signature cooled EGR with integrated DPF, and ratings up to 615
peak hp and 2050ftlb torque. All complemented by class leading
cooling packages now with a wider, lower grille opening in front of
the high efficiency radiator.
K200 - Revolutionary redesign...
Since first introduced in 1971, well in excess of 11,000
Australian designed and manufactured K series C.O.E.'s have been
sold in Australia and New Zealand. In this time there have been
many new K series models and enhancements. However the K200
represents a step change in this journey. New design technologies
abound in the new model, including enhanced cooling capacity,
exterior and interior styling, improved access, storage and much
much more.
The K200 story starts with dramatic new styling from a wider and
lower grille opening and chrome surround. This wider opening, along
with the standard contoured FUPS bumper, promotes greater air flow
through the new cooling package, which includes a new charge air
cooler, moulded fan shroud and 9 blade fan, for increased cooling
efficiency.
The improved cooling package consists of a new Charge Air Cooler
(CAC) optimized for performance and minimized shadowing of the
radiator. The auxiliary coolers have been relocated for remote
cooling and to reduce shadowing. Revised radiator seals and fan
shroud enhances air draw and management through the cooling
package, improving cooling performance and promoting fuel
economy.
Cab height has been raised by 50mm with enhanced under cab and
engine tunnel heat and noise shielding. The double skinned engine
tunnel has been improved, and a double skinned floor now extends
across driver and passenger areas for improved heat and noise
insulation.
There are new dual 7" round contoured chrome headlight
surrounds, and LED high visibility front turn signal.
The new cab access system provides a larger free flowing top
step that supplements existing access standards, which already
provide for consistent step dimensions, and allow the driver to
maintain continuous three points of contact at all times by
utilising grab rails and steps.
The steps also feature durable non-slip surfaces and LED
illumination within the cab foot wells. The LED step lights are
integrated with the remote control central locking system to
automatically illuminate the cab access steps when the cab is
unlocked. This enhances safe night-time entry and exit from the
cab.
The new doors enhance driver comfort and safety by offering an
excellent field of vision from the seated position, out towards the
sides, and into the rear view mirrors, as well as the enhanced
comfort and convenience of the wider armrests with integrated
controls for mirrors and the standard electric windows.
Once inside the cab, the K200 interior features a luxurious high
quality finish with greater use of soft ‘plush' vinyl and
recessed panels, as well as a fresh contemporary range of new trim
colours.
There are new seat options and locations, aligning the driver's
seat with the steering wheel, providing both driver and rider with
30mm more shoulder room and more rider leg room .
The new cab floor is almost flat, with a lower engine tunnel so
a six foot tall driver can stand upright in the aerodyne version.
The gearshift has a wider gate for easier shifts. A fold-away gear
lever allows easy access to the sleeper area. There's also space
under the bunk for two 30lt fridges or storage drawers, all within
easy reach of the driver.
The instrument layout features a warning light cluster designed
to provide the driver with all the required warning devices and
signals within the same dash location, enabling the driver to be
less distracted from the road ahead.
The overhead console includes a further storage locker and
recessed panels for improved finish incorporating provision for
dealer fitted GPS navigation or other driver information
displays.
Power and performance come from a range of engines including
Cummins ISX or Signature, both with cooled EGR and DPF and up to
615 peak hp and 2050lbft of torque - complemented by class leading
cooling packages.
Like other models in the range, the K200 also offers access to
the full suite of EBSS, tested and proven in Australia for our
Australasian operating conditions and applications, and the option
of Ultrashift plus for the ultimate in automatic transmissions, and
the enhanced ease, safety and convenience that they represent for
all drivers.
These combined features have been specifically designed to
enhance driver appeal, comfort and safety with an even higher level
of overall quality.
The Kenworth K200 cab-over is the best choice when it comes to
maximising your bottom line for B-Double applications. The K200
provides operators with exceptional power and flexibility, so they
can haul bigger loads with greater ease. The K200 is versatile
enough to suit most applications in Australia, particularly 25m and
26m B-Double and B-Triple combinations.
The K200 has been designed first and foremost with maximum
productivity in mind. It is now not uncommon for line-haul B-double
customers to be pushing past 450,000 kms per annum utilisation. To
do that you need a truck with the right amount of power and one
that can be relied upon to be available for work day-in, day-out. A
truck that offers maximum flexibility in specifications in a
package drivers want to drive - the K200 certainly fits the
bill.
T4 Series - Overview
Kenworth has placed a lot of emphasis on enhancing the T4 series
model range for 2011. The new T4 series range features three new
models, the aerodynamic T409 and T403 and the more traditionally
styled T409SAR.
They all feature bulkhead electrical connections for better cab
sealing, the new Delphi heating/air-conditioner unit for enhanced
cab comfort, and new doors with standard electric windows, wider
armrests with central locking, integrated mirror and window
controls.
The in cab environment has been even further improved with a
wide choice of contemporary trim colours for the T409 and
T409SAR.
For the aerodynamic T409 and T403, the new models include a host
of customer benefits including revised styling, enhanced cooling
efficiency with streamlined side air intakes and improved seals,
and wider restyled aerodynamic hood and grille. The standard
contoured FUPS bumper also directs air into the engine compartment
for cooling efficiency.
There are new hood mounts located on the chassis rail and
independent of the cab for greater durability, and a new hood tilt
assist system for added safety and convenience.
Both the T409 and T409SAR models are also available with 28",
revised 36" and 50" integrated "aero" sleeper options. The 36"
recessed back version provides additional dip clearance for maximum
deck space 26m refrigerated operations.
Again, Kenworth's application engineering process has delivered
optimized installations to integrate EGR emission solutions
seamlessly across the T4 series.
The T4 series of truck has been designed to offer our customers
a very versatile truck range - the ideal solution for customers
operating 19m and 26m combinations where a conventional is the
preferred choice.
T409
The T409 has been developed in Australia as a flexible and
aerodynamic solution for on-highway operation. It offers the ideal
aerodynamic conventional solution for general freight or tanker
operations. With up to 550 peak hp available, the T409 is the
perfect truck for maximum capacity 19 and 26m combinations where
overall length is critical.
The T409 has ADR 80/03 compliant Cummins engine options with
ratings up to 550hp and 1850lbft.
With sleek styling the T409 has been designed with aerodynamic
efficiency and fuel economy in mind. The new larger hood and
styling incorporates a new grille, eye catching aerodynamic side
fairings and full fuel tank fairing option and new aero style FUPS
compliant alloy bumper.
T409 SAR
The T409SAR offers similar features to the T409 but in a more
traditional package.
With its set forward front axle setting, the truck has been
specifically designed to provide maximum payload for 19m B-Double
and 19m Quad Dog applications. It also fits within the 26m envelope
for B-Doubles.
Reflecting its function as a tough workhorse, the T409SAR features
the classic Kenworth flat grille and hood.
The front axle location allows increased payload for 19m quad
dog applications. There is also a standard "Texas style" alloy FUPS
compliant bumper and FUPS bull bar options.

trailer, some vocational 19m B-Double and rigid applications, the
T403 utilises set back front axles and optimal bumper to back of
cab dimensions, and can deliver up to 70 tonnes under PBS in tipper
and dog applications.
Distinctive with painted grille and headlight surrounds, the
T403 delivers aerodynamic excellence in eye catching style. The
T403 offers similar features to the T409 but with a Cummins ISX
cooled EGR with DPF engine set at 450hp (465 peak hp) for optimal
power and economy in its target applications.
Two trim colours are now available - Wheat and Shiraz;
contemporary alternatives for the new T403s.
T359
The tight turning circle and short bumper to back of cab
measurement makes the T359 the ultimate performer for urban and
intrastate operations, with great manoeuvrability and
visibility.
T3 series customers are already aware of the benefits of running
this truck in urban and intrastate operations where previously they
may have thought a cab over was the only sensible option.
Customers who operate interstate line-haul style long distance
haulage operations expect maximum productivity and high
utilization, and therefore reliability and durability. Many of
these customers are now demanding the same vehicle attributes for
their local operations running into and out of Distribution Centres
24/7.
The T359 is an ideal choice for these high capacity metropolitan
applications, where it goes to work as in prime mover and rigid
versions; perfect for where access is limited, excelling as it
moves in and out of tight spaces and through traffic day in day out
- an urban classic.
It is also a good example of Kenworth's ability to application
engineer specific models and features for niche markets - for
example high volume urban concrete operations, where the T359A
delivers as a highly durable but low tare weight truck able to cart
the maximum amount of cubic meters of concrete over a long life
span.
The T359 and T359A are available in 6 x 4, 8 x 4 and now 10 x 6
axle configurations. With good turning circle and exceptional
driver visibility they offer optimum payload and maximum concrete
carrying capabilities respectively.
Power is from Cummins ISLe5 SCR with options from 260 - 380hp,
up to 1250 lbft torque and a powerful engine brake, It has
Autoshift capability, and an AdBlue tank and vertical or horizontal
Catalytic Muffler as part of the SCR system.
The T359 cabin is available in Slate coloured trim.
T659
With an unmatched reputation for being rugged, reliable and
tough, the Kenworth T659 is designed and built in Australia to
handle the most brutal jobs the country has to offer, both on and
off the highway. Whether you need to haul a triple road train on a
back road, or a load of logs out of a forest, you'll do it easily
and in more comfort and style when you're behind the wheel of a
T659.
The T659 is renowned for its ability to keep its cool on the
hottest of days and with the highest loads. Designed to offer many
years of trouble free operation in the harshest conditions
Australia can offer, the T659 builds on this heritage of a no fuss,
reliable and durable truck that is easy to maintain. So when you
are far from help on a lonely back road with 6 decks of cattle the
T659 provides the reassurance that it will get through and get you
home again.
The T659 is available with up to 615 peak hp and 2050lbft of
torque, from a choice of engines including Cummins ISX EGR and
Signature EGR. Both come with a larger 7" exhaust as standard.
Inside the cab still features a simple flat dash layout and
Kenworth's hard wearing trim for durability and comfort, but now
with new trim colours, new doors and the proven Delphi heater/air
conditioner unit.
T909
For sheer awe-inspiring road presence there is nothing on the
road that compares to the Kenworth T909. However Kenworth's
tradition of classic styling continues with much more than just
good looks.
An almost endless array of options and features, and a range of
both modular and integrated sleepers means Kenworth can tailor the
T909 to suit a multitude of applications and needs; from high

APPENDIX 1:
Exhaust Gas Recirculation with a Diesel Particulate
Filter
For the higher horsepower options, comprising Cummins cooled EGR
ISX and Signature engines, Kenworth will be introducing a Cummins
Particulate Filter integrated with the engine's cooled Exhaust Gas
Recirculation (EGR) technology.
The filter, which incorporates a diesel oxidation catalyst and a
diesel particulate filter to reduce NOx and particulate matter,
replaces the existing vehicle muffler. It reduces particulate
emissions by 90% from current levels and is designed to last the
life of the engine.
For T4 series and above utilizing Cummins ISX or Signature
engines, an important component of the Cummins DPF system is the
larger 7" exhaust diffuser tail pipes, which allow cool air to
travel up through the exhaust to help control exhaust
temperatures.
This DPF technology is not new to Kenworth or Cummins. In fact,
there are over 450,000 of these filter units in operation today in
North America, meeting the EPA 2007 and 2010 on-highway emissions
standards with proven success.
Exhaust flows out of the engine and into the Cummins Particulate
Filter. It passes through the diesel oxidation catalyst where
chemical reaction break down the NOx emissions. It then flows into
the diesel particulate filter where the particulate matter, or
soot, is collected on the walls of the filter.
The carbon (soot) collected is then oxidized to remove it from the
filter. This process is called regeneration, and takes one of two
forms:
- Passive Regeneration: Occurs automatically when the vehicle's
duty cycle and exhaust temperature drive the continuous oxidation
of carbon. No actions are required by the engine or operator to
keep the particulate filter clean.
In typical Australian B-double linehaul operations, passive
regeneration is expected to occur around 95% of the time.
- Active Regeneration: Occurs when the duty cycle does not
generate enough heat to convert all the carbon being collected in
the particulate filter.
In this case, the engine ECM initiates an active regeneration by
injecting a small amount of diesel into the exhaust stream, which
generates heat as it enters the filter. This additional heat
ensures that excess carbon is oxidized without any operator
intervention
Selective Catalytic Reduction
The Cummins ISLe5 utilises SCR to meet the new standard. The SCR
process purifies the NOx of diesel combustion engines by
introducing an additive, a urea solution, after the combustion
process. The urea solution then converts the exhaust emissions to
water and Nitrogen, meeting the 2011 regulations.
