Cascadia

When it comes to the noise in regular trucks, it’s typically not just one rattle. It’s lots of tiny little noises that add up to a racket. So we locked our engineers in the cab with sound sensors (“electronic sonar technology,” they call it) until they’d identified and quieted all the squeaks, rattles, hums and noises. The result: a truck that rides like a quiet luxury car and reduces driver stress and fatigue.

Cascadia’s Cone of Silence
The stiffness of the curved walls already reduces vibration noise. Then we removed the skylight so we could nest the entire Cascadia cab and sleeper in a thick blanket of noise-dampening insulation. Then we covered everything inside — even under the flooring and around the firewall — with more sound-proofing materials. So behind the wheel or asleep in the bunk, the cab is dramatically more quiet.

Better Sleep Means Safer Roads
Whether you’re behind the wheel driving or behind a desk managing, safety is your top priority. Studies have shown the louder the cab, the worse the sleep. Science has linked bad sleep to slower reaction time and feelings of annoyance and aggravation: a witch’s brew for the road. Even experienced drivers who are “used to it ” wake several times a night without being aware of it. So we surrounded the cab with loads of extra insulation to keep it quiet for improved sleep, and ultimately safer roads.

The Best Seat on the Road
If this seat was any more comfortable, it’d have a wooden arm to pop up the footrest. We know you’ll love the dimensions: the seat is two inches wider, two inches longer and goes two inches higher. Optional features include a seat-heater, swivel and three-way bolster. The seat’s great not because it fits so many different people, but because the adjustability means it will fit YOU.

Better for the Bottom Line
From the tires up, the ride in the Cascadia was fine-tuned to reduce road-buzz. The seat, for example, has its own shock absorber that we tuned to the truck suspension. So rather than feeling like you’re sloshing around on a waterbed, you feel just the smooth comfort of the truck.

Modeling the Future
Freightliner engineers embraced computer 3D modeling of the truck early on. Because aerodynamic changes are so complex, designers and engineers could try wild ideas in the virtual wind tunnel to see what worked best without waiting to test prototypes in the wind tunnel.

Born in the Wind Tunnel
Engineers then proved the computer model’s aerodynamics by logging over 2500 hours in our wind tunnel. By comparison, other trucking companies just rent time, paying usually for only 200 hours in the wind tunnel. Ours is the only wind tunnel owned by a North American truck manufacturer.

Can You Hear It Now?
Our sound engineers threw down the gauntlet: no racket in the Cascadia. They gridded off the entire interior, and listened to every square inch with a super-sensitive microphone. They measured noise while the engine roared. They isolated and stopped wind noise in the wind tunnel. And they tracked down and killed the buzzes, rattles, and squeaks. Shhh. Just enjoy the quiet.

Built Like a Luxury Car

Double skinned, stamped walls make the truck stronger — Cascadia easily passed all safety tests — and reduced audible vibration frequency by 50 percent. In fact, no other heavy duty truck on the market has stamped cab walls put together with such micro-precision. Even in the car market, only luxury brands like Mercedes-Benz, Jaguar, and Audi are manufactured this way.


A New Truck with Years of Experience
With new features like available rack and pinion steering and an overhauled HVAC, we couldn’t let Cascadia on the road until it passed some extreme testing. Take a tour of the torture chamber:

  • Climate Chamber: Components must keep working, wet or dry, from -40 to 130 degrees Fahrenheit.

  • Torture Track: Two miles of rocks, potholes, curbs and curves.

  • The Shaker: We record the torture track jolts, then replay it for six straight weeks.

Boot and Glove Engineering
Our test fleet was fertile ground for ideas. We counted more drivers at both ends of the size spectrum: big men who needed a bigger seat, and small women who needed a more adjustable chair. They got it. Then we noticed drivers banging their feet around near the pedals, so we increased footwells to comfortably fit working boots. And we built all controls in the cab to be usable, even with work gloves on.

DD15: Advanced Doesn’t Mean Complicated

When Detroit Diesel designed the DD15, they focused on integrating simple, smart technology for added power and fuel efficiency. Turbocompounding adds up to 50 horsepower without a drop of extra fuel. The integrated Jake Brake is more powerful and quieter. And the Amplified Common Rail System saves wear and tear on the fuel injection system while producing fewer emissions with no loss of power.

Intelligent Diagnostics For All
The Cascadia electrical system is a state-of-the-art design that takes advantage of new diagnostic tools, yet blends the best of traditional systems as well. This dual functioning system of “part multiplexing and part traditional” technology is common in the automotive world today because you get increased diagnostics and easier parameter changes. Yet it is not a completely proprietary system, so technicians from any Freightliner dealership can access diagnostics you need to keep driving, such as the engine and transmission Electronic Control Units (ECUs). When the truck is a long way from home, this can slash downtime and repair costs.

Flexible Electrical System
Want the brake lights on whenever the engine brake is activated? In the past, you’d have to hard-wire something like that. Cascadia’s flexible electrical system lets a fleet technician set this and many other options. By opening the electrical system, your fleet can adds lots of very inexpensive options for running your trucks.

The easiest way to save on fuel?
Own a more aerodynamic truck that needs less fuel to push itself through the wind. Like the Cascadia. For months and months, our engineers tweaked and tested full-scale models in our own wind tunnel to deliver fuel saving aerodynamics.

Choose Power or Fuel Efficiency. Or Choose Both
Fuel economy or pulling power? Don't choose. Demand it all. The new Detroit Diesel DD15™ gets up to 5% better fuel economy and snappy acceleration with up to 50 free horsepower. Depending on the needs of your fleet, you can also choose the Cummins ISX or two other do-everything Detroit Diesel engines.

“Torque Response” is engineering-speak for get-up from a dead stop. And the Detroit Diesel DD15™ is 75% faster than a Series 60®. Even fully loaded, you feel yourself launching up the on-ramps. The DD15 is loaded with up to 560 HP and up to 50 free horsepower from the turbocompounding. Plus it hits it maximum torque as low as 1,100 RPM, so you’re not grabbing for gears climbing the hills.
