Slice the Wind (and Your Fuel Tab)

• Hood that's been lowered and sculpted
• Bumper that directs air into the radiator and around wheels
• Windshield that's sloped and curved an extra 2 degrees
• Marker lights that are flush with bright and durable LEDs
• Break-away side extenders flared for tight turns with a trailer
• Mirrors on door and hood curved for wind-cutting and stability
• Roof header that's sharpened
• Fog lamps that are flush

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 the most aerodynamic truck on the planet.

Proven Aerodynamics

And that's not just big talk: we had the independent Auto Research Center (ARC) double-check our numbers the same way they validate aerodynamics data from Formula One and NASCAR. Use the Fuel Calculator to the left to see how much money Cascadia's aerodynamics could save your company.

Born in the Wind Tunnel

Engineers proved the computer model's aerodynamics by logging over 2500 hours in our wind tunnel. By comparison, other trucking companies use only 200 hours. Our guys aren't slow; they nipped, tucked and flared every little surface on Cascadia. Gaskets, mirror shapes, bumpers, headlights. They tested, tested, and tested again. They even improved the aerodynamics UNDER the hood to reduce aerodynamic drag.

Designed for EPA ‘07, and Beyond

The Cascadia was designed to easily accept EPA 2007 and 2010 emission engines. We incorporated everything into the design to meet the regulations for the next several years. And we were able to do this with cooling packages that don’t block your view of the road.

So Long, Radiator Struts

Both the radiator and fan shroud are mounted to the engine, which means your mechanic won’t need to be double-jointed to get in there. Even better, it means more air is drawn through the radiator instead of around it, cooling your engine more efficiently.

Getting There with Cleaner Air

The Freightliner Cascadia meets and exceeds the EPA Smartway voluntary specifications that dramatically improve fuel economy and reduce emissions. The aerodynamic shape and features of the Cascadia, along with features like the ultra-efficient DD15 engine, can reduce fuel consumption by 10-20 percent, according to the EPA.

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 from two other do-everything Detroit Diesel engines, or the Caterpillar C15.

It’s All about Weight

Like all Freightliner highway trucks, the Cascadia cab is made from aluminum that weighs significantly less than steel. And the less the cab weighs, the more payload the truck can haul. Which means more revenue per trip.

“Idle” is a Four-Letter Word

Idling the engine to run the heat or AC while you sleep isn’t just an expensive waste of fuel, it’s against the law in many states. So we added an optional battery-powered HVAC unit that runs up to 10 hours before needing a recharge.
