Introducing the Kenworth W990: Where Modern Technology Meets Classic Style
November 27, 2025 - 8:09:56 am

For decades, the "long hood" truck has been the symbol of the American road. It represents independence, power, and a pride of ownership that runs deep in the trucking industry. But in a world increasingly driven by efficiency and technology, drivers often feel forced to choose between the truck they want to drive and the truck they need to drive.

The Kenworth W990 changes that.

At Wallwork Truck Center, we understand that your truck is more than just a tool; it’s your home, your office, and your signature. The W990 is designed to be the ultimate compromise-breaker, blending the commanding presence of a classic long-hood conventional with the cutting-edge technology and aerodynamics of a modern day-cab.

This is a detailed look at the Kenworth W990—a truck that proves you can have it all.

The Look: Unmistakably Kenworth

The first thing you notice about the W990 is that it refuses to blend in. It honors the legacy of the legendary W900 but brings it forward into a new era.

• The Long Hood: With a bumper-to-back-of-cab (BBC) measurement of 131.5 inches, the W990 maintains that traditional long-nose profile that drivers covet. It’s a bold statement on the highway that commands respect.
• The Grille: The "cathedral" grille is a stunning centerpiece. It is constructed from premium stainless steel and features a vertical-bar design that is instantly recognizable as a Kenworth, signaling quality and heritage from a mile away.
• Aerodynamic Refinement: While it looks classic, the design is deceptively slippery. The hood is sculpted from a durable composite material that assists airflow. The windshield is curved, and the fenders are swept back. These subtle changes result in significant aerodynamic improvements over the classic W900L, translating directly to fuel savings without sacrificing the "square hood" aesthetic.

Power and Performance: Built to Work

A truck that looks this good needs the muscle to back it up. The Kenworth W990 is engineered to handle everything from heavy-haul lowboy work to coast-to-coast refrigerated freight.

The PACCAR Powertrain

At the heart of the W990 is the proprietary PACCAR powertrain, optimized for efficiency and reliability.

• PACCAR MX-13 Engine: This 12.9-liter engine is the standard-bearer for efficiency. It offers up to 510 horsepower and 1,850 lb-ft of torque, providing plenty of pulling power while maintaining excellent fuel economy.
• PACCAR TX-12 Transmission: This automated transmission is designed to work seamlessly with the MX-13 engine. It features intelligent shifting logic, low-speed maneuverability for tight docks, and lightweight construction to maximize payload.
• PACCAR DX-40 Axles: Completing the drivetrain, these axles are built for long life and efficient power delivery.

The Cummins X15 Option

For those who demand raw power for heavy applications, the W990 is also available with the Cummins X15 engine. This beast can be tuned up to 605 horsepower and 2,050 lb-ft of torque, making it the ideal choice for heavy haulers who need to move mountains.

The Driver’s Studio: A World-Class Interior

The exterior may say "classic," but the interior screams "modern luxury." The W990 utilizes Kenworth's 2.1-meter cab, providing a wider, quieter, and more spacious environment than previous generations.

The "Driver's Studio" Package

For the ultimate over-the-road experience, the W990 offers the limited-edition "Driver's Studio" package. This isn't just a sleeper; it's a high-end apartment on wheels.

• Rotating Passenger Seat: The passenger seat swivels 180 degrees to face the sleeper, creating a comfortable lounge area when parked.
• Swivel Table: A rotating table allows two people to sit and eat or work comfortably, then stows away to maximize space.
• Premium Audio: A 320-watt amp, 10-inch subwoofer, and eight speakers provide concert-hall sound quality.
• Ample Storage: From a full-size wardrobe to deep drawers and dedicated spaces for a microwave and TV (up to 28 inches), everything has its place.

Technology: The Smartest Long-Hood on the Road

The Kenworth W990 integrates technology that improves safety, uptime, and the driving experience without cluttering the classic feel of the cab.

The 15-Inch Digital Display

Gone are the days of worrying about a stuck gauge. The W990 features a state-of-the-art, high-definition 15-inch digital instrument cluster.

• Customizable: You can choose what information you want to see, from simple speed and RPM to detailed engine diagnostics and trip data.
• System Check: At the start of every shift, the system runs a comprehensive "System Check," giving you a green light on vital systems like oil pressure, air pressure, and fluid levels before you even release the brakes.

TruckTech+ Remote Diagnostics

Uptime is money. The W990 comes equipped with Kenworth TruckTech+. If a check engine light comes on, the system immediately sends a notification to you and your fleet manager. It diagnoses the severity of the issue, telling you if you need to pull over immediately or if you can keep driving to your next service stop. It’s like having a certified technician riding shotgun.

Driver Assistance Systems

Safety is paramount. The W990 offers advanced driver assistance systems (ADAS) including:

• Adaptive Cruise Control: Automatically adjusts your speed to maintain a safe following distance.
• Collision Mitigation: Detects potential crashes and can automatically apply brakes to reduce severity.
• Lane Departure Warning: Alerts you if the truck begins to drift, preventing fatigue-related accidents.
