Optimizing 2022 Freightliner Cascadia Fuel Efficiency with Aero Kits | Turn Your Truck Into a Fuel-Sipping Machine
You’re running a 2022 Cascadia—one of the most aerodynamic trucks ever built—and you’re averaging 8.5 mpg. But Henry Albert is out there pulling 10.5 mpg in the same model year, and you can’t help wondering: what’s he got that you don’t?
TL;DR
The 2022 Freightliner Cascadia is already 35% more fuel-efficient than the first-generation model from 2007, thanks to relentless aerodynamic refinement . But real-world results show a massive gap between average drivers and the best in class—with top performers like Henry Albert achieving 10.5 mpg lifetime averages and peaks over 13.7 mpg . The secret lies in combining the right factory aero specs with aftermarket additions and disciplined driving techniques. Key factory options include the AERO X package (adding ~5% efficiency), 23-inch cab extenders to close the tractor-trailer gap, and the MirrorEye camera system (saving 2-3% by replacing traditional mirrors) . Aftermarket solutions like FlowBelow wheel covers and fairings add another 2% savings, while trailer skirts and tails maximize the complete aerodynamic system . The result? A properly optimized 2022 Cascadia can outperform the fleet average by 2-4 mpg—translating to $5,000-$10,000 in annual fuel savings.
Key Takeaways
- The 35% milestone is just the starting point—2022 Cascadia aero refinements build on decades of development, but driver choices still create massive performance gaps
- AERO X package is the factory gold standard—adds low ground clearance bumper, optimized roof fairings, front wheel well closeouts, aerodynamic ride height control, and exclusive Michelin tires for a 5% gain over base
- Cab extenders matter more than you think—23-inch extenders close the turbulent gap between tractor and trailer, a $500 upgrade with measurable ROI
- MirrorEye saves 2-3% on fuel—replacing traditional mirrors with cameras reduces drag while improving visibility
- FlowBelow adds another 2%—independent testing shows wheel covers and drive fairings deliver verified savings on Cascadia platforms
- Lift axles are aerodynamic too—the Hendrickson OptiMaax system lets you run on fewer axles when lightly loaded, reducing drag and tire friction
- Trailer aero completes the system—full side skirts and trailer tails maximize the investment in tractor aerodynamics
The 2022 Aero Foundation: What You Already Have
The 2022 Cascadia didn’t start from scratch—it’s the culmination of nearly two decades of aerodynamic refinement. Since the model’s 2007 debut, Freightliner has improved fuel efficiency by more than 35% , with each generation adding incremental gains.
Standard Aero Features
Even a base 2022 Cascadia comes equipped with:
- Optimally sloped hood and grille
- Bumper with integrated air deflector
- Aerodynamic mirrors
- Upper door seals
- Integrated antennas
- A-pillar deflectors
- Tow hook covers
The AERO X Package
If your truck has the AERO X package, you’ve already added approximately 5% efficiency over a standard 2017 model . The package includes:
| Component | Function |
|---|---|
| Low ground clearance bumper | Reduces air under the truck |
| Optimized roof fairing deflectors | Smoother transition to trailer |
| Front wheel well closeouts | Blocks turbulence from front tires |
| Enhanced chassis fairing skirts | Longer, closer-to-ground side skirts |
| Optimized drive wheel fairings | Reduces wheel turbulence |
| Aerodynamic ride height control | Lowers truck 1″ above 55 mph |
| MICHELIN X LINE ENERGY D+ tires | Low-rolling-resistance rubber |

Factory Options That Pay Off
The AERO X Package
The AERO X package is Freightliner’s most comprehensive aerodynamic offering. According to Heavy Duty Trucking, this package alone delivers a 5% fuel economy improvement over the 2017 model , and when combined with other refinements, the 2022 Cascadia is 35% more efficient than the 2007 original .
What’s included:
- Low ground clearance bumper with flexible air dam
- Optimized roof fairing deflectors
- Front wheel well closeouts
- Enhanced chassis fairing skirts
- Optimized drive wheel fairings
- Aerodynamic ride height control (lowers truck at highway speeds)
- MICHELIN X LINE ENERGY D+ tires
MirrorEye Camera System
The Stoneridge MirrorEye system replaces traditional mirrors with cameras, and Nussbaum Transportation reports it can save as much as 2-3% on fuel costs by reducing aerodynamic drag . The system uses:
- Five exterior cameras (two per side plus look-down)
- Three interior monitors
- Hydrophobic coated lenses
- Heated elements for ice/snow
Beyond fuel savings, drivers get improved visibility and eliminated blind spots—a safety bonus that pays dividends in accident prevention.
Cab Extenders
Nussbaum specs 23-inch cab extenders on their Cascadias to “reduce the gap between the truck and trailer” . That gap is a major source of aerodynamic drag—air gets trapped and churns between tractor and trailer. Closing it with extenders is one of the simplest, most cost-effective aero upgrades available.
Liftable Axles
The Hendrickson OptiMaax liftable pusher axle is both an aero and efficiency tool. Henry Albert’s 2022 Cascadia uses it to operate on only three axles when loads are light: “Because of having a lift axle, I’m only powering one differential” . This reduces:
- Friction from tires on pavement
- Aerodynamic drag from exposed wheels
- Toll road charges (many tolls are axle-count based)
Albert’s “Garden State Express” route allowed him to run on three axles for five consecutive weeks , demonstrating the real-world savings potential.
Aftermarket Add-Ons That Work
FlowBelow Aero System
FlowBelow has become the gold standard for aftermarket wheel aerodynamics. Independent testing by Mesilla Valley Transportation Solutions on Cascadia platforms showed the full Tractor AeroKit saves 3.16 gallons per 1,000 miles—a 2.13% improvement.
The system includes:
- Quick-release wheel covers for drive wheels
- Center fairings mounted between tandem axles
- Rear fairings behind the wheels
For 2022 owners, FlowBelow components can be added aftermarket, or if you’re spec’ing a new truck, they’re available through Freightliner’s factory data codes.
Trailer Aerodynamics
Your tractor is only half the equation. Warren Gibson Ltd. emphasizes that “aero kits and trailer skirts reduce drag for better fuel efficiency” . Henry Albert’s setup includes:
- Full-length side skirts on his trailer
- Wide-base single tires on all axles (saves 750 pounds and reduces rolling resistance)
The combination of tractor and trailer aero creates a complete system. Albert’s 10.5 mpg average proves the concept works.

The Driver Factor: Henry Albert’s Secret Weapon
All the aero kits in the world won’t save fuel if you drive like you’re in a video game. Henry Albert, who averages 10.5 mpg lifetime and has peaked at 13.7 mpg , proves that driver technique is the ultimate multiplier.
Albert’s Philosophy
“Drivers play a large role in fuel economy,” Albert explains. “Just knowing the spec and the product that they’re moving along, they have a lot of control in the way that they drive” .
He treats every mile as an opportunity to learn, constantly monitoring conditions, anticipating traffic, and minimizing idling—something he’s famously done just once in his career .
Why Efficiency Matters
“I focus real keenly on fuel mileage for a couple of reasons,” Albert said. “One, it’s just the right thing to do—it’s good for the environment. The other is, it’s my number one expense as an owner-operator—my fuel bill” .
Technology as an Enabler
Albert’s 2022 Cascadia is spec’d for efficiency, but he emphasizes that technology only works when paired with a driver who understands it. “When drivers see all this Freightliner Team Run Smart, they might be struggling with the technology. Showing them how to use it and getting them comfortable with it—knowing their day is going to be better, more profitable, and safer—that’s one of the most rewarding parts to me” .
The Complete Package: Nussbaum’s Fleet Approach
Nussbaum Transportation has sustained a fleet-wide average of 9 mpg , with several drivers exceeding 11 mpg . Their formula combines equipment and training.
