Kenworth’s W900 has become a staple of the show ‘n shine circuit, its long hood and gleaming accents seem to guide drivers down the highway. The look has had a starring role in movies and been immortalized in belt buckles.

Now it has been re-imagined in the form of the W990.

“We’re celebrating the legacy of the W900 and the introduction of the next generation,” said Kenworth general manager and Paccar vice-president Mike Dozier, during a customer launch party at the Las Vegas Motor Speedway. “A lot of passion, a lot of pride, have gone into what we think is a really special product.”

The W900L remains available, he stressed. “But we’re planning for the future.”

Redefining a model like this is no small matter. The W900 has, in one form or another, been a staple of Kenworth’s lineup since 1961. The W is even a nod to Edgar K. Worthington, one of the company’s founding fathers who gave the brand its “worth.”

“Redesigning an icon is a once-in-a-lifetime opportunity for a design team,” added Jonathan Duncan, Kenworth design director. Trucks like Kenworth’s T680 on-highway tractor and medium-duty models are important, he said. But they’re different. “They don’t sing songs about those. They don’t put those trucks on belt buckles necessarily.”

The Las Vegas event was the first opportunity most people outside of the Paccar family have had to soak in the truck’s unique profile. Marketing teams have been keeping the truck under wraps for months, shrouding the distinct hood as it moved to photo and video shoots.

“The driver’s view over the hood, that’s a huge part of the appeal,” Duncan said. “It’s really designed to accentuate the hood … All this creates kind of an emotional connection to the driver.”


Measuring 131.5 inches from the bumper to the back of the cab – 1.5 inches longer than the W900L — the W990 comes as a day cab, with a 40-inch flat top sleeper, and 52- and 76-inch mid-roof sleepers. It also comes standard with a proprietary Paccar powertrain with a 510-hp/1,850 lb-ft MX-13 engine, 12-speed automated transmission, and 40K tandem rear axles.

It’s all built on the same cab platform used in the T680 and T880.

Sitting up front is the largest cooling module found on any of Kenworth’s on-highway trucks, Duncan said. And the shape is 6-7% more aerodynamic than a W900L, although he admits that won’t likely be the main driver for most buyers.

Much of the appeal will focus on the appearance.

The grille at the front maintains what’s described as a “cathedral shape”, with inset surfaces to define a tailored look.

The “wind-split” raised section at the top of the hood itself is meant to accentuate its length as drivers look over the dash. Stainless steel air intakes wrap over the top so they can be seen from the driver’s seat, too, and against some colors they’re said to look twice as deep as they actually are.

Inside, final touches come in the form of a limited-edition cab and sleeper interior, and the W990 Driver’s Studio Package. The interior itself is black, accented by door and dash trim elements made in a glossy ravenwood. Blue accents can be found in the double-stitched diamond door pads, leather-wrapped steering wheel, and the backing for driver and passenger seats that have suede charcoal inserts and perforated leather.

For living quarters, the W990 Driver’s Studio features the passenger seat that swivels 180 degrees and a rotating table for two, drawer-style refrigerator, and space for a microwave. The premium audio package includes a 320-watt amp, 10-inch subwoofer and eight speakers; swivel TV mount for up to a 28-inch flat screen TV; and optional EpicVue pre-wire for satellite TV. There’s an 1,800-watt inverter including a connection for shore power and four standard 120-volt sleeper outlets. The LED lights shine over it all.

The ever-important storage amenities come in the form of a full-size wardrobe, storage drawers, and storage space under the bunk.

While it offers a nod to the company’s heritage, the W990 also comes standard with the latest TruckTech+ remote diagnostics, and the seven-inch color in-cab NAV+HD display for navigation, audio controls, blind spot camera inputs and more.

Paccar Parts was also involved in the process to create aftermarket enhancements like a special LED lighting package and stainless trim.

“They’re going to want to customize their trucks,” Duncan said, referring to early buyers. “We’ve given them a great place to start.”


Kenworth is please to announce the launch of its new Vehicle Electronic Control Unit [VECU] for North America 2.1 meter products.  The VECU enhances the core electrical architecture of Kenworth’s 2.1 meter platform, providing expanded vehicle functionality to further meet the needs of customers in areas such as MX PTO functionality, driver-assistance programs and advanced driver controls.  The new VECU electrical architecture is an evolution on the technology used in the current Cab Electrical Control Unit.  The controller will be expanded in both software capacity and signal input/output.  All North American 2.1 meter base models will come standard with VECU starting in October.

Kenworth is pleased to announce the availability of Dana 172 series axles.  These axles replace the Dana 170 series axles, and, according to Dana, provide increased durability, reliability, and efficiency while reducing weight.  The 172 series axles feature design improvements on the rear axle housing/carrier interface, internal gearing improvements and increased torques capacity for certain applications.  The Dana 172 rear axle uses 10 pints less lube than the Dana 170.

WABCO has released a new 500k baud rate camera for its OnLane Alert System in T680 and T880 models.  The camera replaces the 250k baud rate camera.  OnLane Alert is a camera-based warning system that helps vehicles avoid unintentional land drifting.  The system utilizes a camera mounted near the top center of the windshield to monitor and calculate the vehicle’s position within the lane.  When OnLane Alert detects the vehicle crossing land markings without the turn signal being activated, the system sounds an audible warning.  This alerts the driver to take a corrective action to prevent potential collisions or run-off-road accidents,

Beginning August 1, 2019 Phase 2 of the Federal Motor Vehicle Safety Standard 136 , Electronic Stability Control, becomes effective for all tractors with a Gross Vehicle Rating greater than 26,000 pounds.  This phase implements for both U. S, and Canadian chassis.  Phase 1 of the standard took effect August 1, 2017 for 6×4 tractors.  Phase 2 will include all other tractors, including 4×2, 6×2, tridems, and lift axles.  Any tractor featuring a single axle with an engineering assigned GVWR of 29,000 pounds or more is excluded.  Full trucks and gliders are also excluded.  To ensure chassis will be manufactured in time to meet the August 1, 2019 requirement, Kenworth will implement Phase 2 of the standard for trucks scheduled July 1st, 2019 and beyond.

Dana Spicer’s S140 single-reduction single-drive axle is now standard equipment on medium duty models T270 and T370.  The T270 features the S17-140 rated at 16,000 pounds while the T370 is spec’ed with the S21-140 rated at 21,000 pounds.

Kenworth announces the expanded availability of the WABCO OnGuardActive Collision Mitigation System and WABCO SmartTrac Electronic Stability Control to K270 and K370 models.  Automatic Traction Control is now part of the standard WABCO Electronic Braking System and will be included with all K270s and K370s moving forward.  OnGuard Active and Electronic Stability Control both require Automatic Traction Control.  The OnGuardActive Collision Mitigation system supports drivers with collision warning and autonomous brake application to help avoid or mitigate collisions.  OnGuardActive applies braking on moving, stopped and stationary vehicles and also provides maximum speed reduction up to -3.5m/s2 to minimize impending collisions.
