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.

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.
