ONE of the highlights at PACCAR World was the new ergonomically designed Kenworth cab interior, which will be introduced to the entire conventional truck range from May this year.

The new cab was on show in a cut-away cab exhibit.

Kenworth's conventional cab has undergone a major upgrade - both inside and out.

It includes a host of innovations which greatly improve driver comfort, safety and productivity.

The new Business Class interior is decked out in fresh, contemporary colour schemes and styling.

It includes Kenworth's Smart Wheel steering wheel with finger-tip controls, a curved dash and overhead console, and a privacy curtain; all of which make a more roomy, functional driver environment.

Full-length grab rails provide safer entry and exit from the vehicle, by enabling three-point contact to be maintained at all times.

Andrew Hadjikakou says the new conventional cab and Business Class interior is the result of two years research and development, and takes cues from Kenworth's K200 cab-over interior, which received rave reviews from customers following its recent interior upgrade.

"We were overwhelmed by the positive response to the K200's new interior.  Operators were impressed with the driver-friendly innovations and overall spaciousness and comfort. That feedback inspired us to go one step further with the cabs in our conventional trucks," he said.

Andrew said the first challenge was developing an identical cab across the conventional range, not only in look and feel but also dimension.

The end result provided a bonus for customers of the T359, T659 and C509 models.  The new, uniform cab is larger than their previous cabs.

"The new T359 cab has a higher ceiling and more depth. This provides more head space and room for seat adjustment which will benefit larger drivers.

"The T659 and the C509 cabs also have more seat room and a curved windscreen, which is now standard across the conventional truck range," he explained.

The first thing you notice inside the cab is the ergonomically-designed dash and overhead console which curves around the driver. This improves visibility and provides easier access to all instruments and information displays.

Andrew says Kenworth rethought the entire layout, repositioning frequently used equipment closer to the driver and less-used items further away.

Radios and auxiliary switches have also been moved from the overhead console to improve driver safety.

At the centre of the dash is a fully-functional Smart Wheel with buttons on the wheel for conveniently controlling vital operating functions, including the truck's engine brake, cruise control and high-beam headlights.

All electronic service components, HVAC and electrical circuitry have been relocated behind a new panel in front of the passenger seat.

This provides better access, and makes repairs and maintenance easier.

Another thoughtful addition is an interior privacy curtain which wraps around the entire windscreen and both door windows. Made from heavy-duty vinyl, the curtain provides complete privacy for changing or sleeping.

It also enhances the cab's living space by visually separating it from the outside world.

This makes it more comfortable for relaxing, watching TV or attending to paperwork.

Kenworth's new Business Class interior comes complete with bright, contemporary colours which open up the driver environment, making it feel even more spacious.

The trim is durable vinyl that is easy to clean and maintain.
