NOT JUST A TRUCK — A SYSTEM ENGINEERED TO LOWER COST PER MILE.
Every component of the Gen 5 Cascadia — aerodynamics, powertrain, driver environment, and safety — works together to cut fuel spend, protect uptime, and keep your best drivers in the seat. Here's how each piece earns its keep.
2027 Freightliner Cascadia · Fuel Savings
THE NUMBERS THAT MATTER
A new Cascadia Gen 5 delivers 8.5+ MPG versus roughly 6.0 MPG on an older used truck. Across a fleet, that delta compounds fast — plug in your numbers below.

Exterior · A Closer Look
EVERY PANEL EARNS ITS KEEP
Every exterior detail was designed for less drag, lower upkeep, and a sharper look mile after mile.
CASCADIAExterior
123456701
Full-Length Roof Spoiler
Manages airflow over the gap between cab and trailer — the biggest single source of drag — across the full width of the cab.
02
Aero Mirror System
Low-profile, aerodynamically shaped mirrors cut drag and wind noise while improving the driver's sightlines.
03
Fifth Gen Aerodynamic Hood
A reshaped nose profile reduces how hard the air hits the front of the truck — the starting point of the whole aero system.
04
Aerodynamic LED Headlamps
Bright, efficient LED lighting with lower power draw and a far longer service life than halogen.
05
Molded-In Color Side Fairings
Color is built into the material, not painted on. Rock chips and road rash don't mean repaints — fewer body-shop trips.
06
Low-Clearance Chassis Skirts
Smooth the airflow underneath the cab, reducing drag from below to complete the aerodynamic package.
07
Polished Aluminum Wheels
Durable, corrosion-resistant, and easy to keep sharp — they hold their look over the life of the lease.
Exterior & Aerodynamics
ENGINEERED AS A COMPLETE SYSTEM
The Gen 5 Cascadia wasn't styled to look good — it was engineered as one aerodynamic system. Walk a prospect around the truck and you can point to each element and connect it to real dollars.
01
Fifth Gen Aerodynamic Hood
A reshaped nose profile reduces how hard the air hits the front of the truck — the first element in the full aerodynamic system.
"The redesigned hood isn't cosmetic — it's the first piece of an aerodynamic system that runs the entire length of the truck."
02
Full-Length Extended Roof Spoiler
Manages airflow over the gap between cab and trailer — the single biggest source of drag on any combination vehicle — end to end, not just partially.
"The space between the cab and the trailer is where most of the drag comes from. This spoiler manages that gap for the full width of the cab."
03
24" Side Extenders, Flexible Ends
Seal the sides between the cab and the trailer to prevent turbulent air from entering the gap.
"Aerodynamics are critical for fuel efficiency — and sealing the sides is where a lot of it is won or lost."
04
Low-Clearance Chassis Skirts
Smooth airflow underneath the cab, reducing drag from below and completing the package.
"Turbulence under the truck is a real drag source. The chassis skirts manage that airflow from below — the final piece."
Integrated Detroit Powertrain
POWER THAT PULLS WHERE IT PAYS — DOWN LOW
The Detroit DD15 Gen 5, DT12 automated transmission, and a tall 2.16 rear axle are tuned to work together in real time — more torque at low RPM means less shifting, less fuel, and less wear.

Integrated Detroit Powertrain
Engine, transmission, and axle make decisions together in real time — smarter shifting, reduced fuel burn, and less wear than independent components.
DT12 12-Speed AMT
A real clutch and real gears with electronic shifting — consistent across every driver, with four selectable modes.
EconomyPerformanceKickdownManual
2.16 Rear Axle + ALM 2.0
A tall 2.16 ratio turns just ~1,050 RPM at highway speed (vs ~1,450 with a 3.36) — lower fuel burn, less heat and friction. Axle Lubrication Management 2.0 cuts internal drag and extends service intervals.
Driver Environment
A CAB BUILT TO LIVE IN
Driver retention starts with the seat and the bunk. The Gen 5 cab is engineered for rest, comfort, and the realities of life on the road — because a satisfied driver is a safer, more productive one.
Elite 2.0 Seat
Heat, ventilation, air suspension, dual armrests, and dual lumbar + bolster support. Less fatigue, better retention.
72" Raised-Roof Sleeper
A 40" liftable lower bunk and foldable upper bunk turn the cab into real living space. Better rest means safer drivers.
Sleeper Amenities
Refrigerator, storage and workspace, 12V + 120V outlets, and an 1,800W pure sine-wave inverter.
CPAP-Friendly Power
Clean, stable power that supports driver health needs through the night — without draining the batteries.
Optimized Idle + ESPAR
Maintains cab temperature automatically and reduces engine runtime — lower fuel use, fewer idle hours, less wear.
LED Lighting Throughout
Bright and efficient, with lower heat output and a longer service life than halogen.

Questions, Answered
FREQUENTLY ASKED
Can I lease the Gen 5 Cascadia as an owner-operator?
Yes. The Cascadia is available through TEL's Independent Owner Operator and Lease-Purchase programs, with low weekly payments and a clear path to ownership.
What's the powertrain?
The Detroit DD15 Gen 5 engine — 455 HP @ 1,500 RPM and 1,750 lb-ft of torque @ 900 RPM, governed at 1,900 RPM and CARB 2024 Ultralow NOx compliant — paired with the DT12 12-speed automated transmission and a tall 2.16 rear axle.
How much can the aero package really save on fuel?
A truck running 7 MPG over 120,000 miles a year burns roughly $68,500 in diesel. Each 1% efficiency gain returns about $685 per truck per year — so a 3% improvement across 25 trucks is more than $51,000 annually.
What warranty coverage comes with it?
Transmission is covered 60 months / 750,000 miles, chassis 36 months / 400,000 miles, engine towing 24 months / unlimited miles, and engine + aftertreatment 4 years / 400,000 miles.
What safety systems are included?
Detroit Assurance — Active Brake Assist 6, Adaptive Cruise Control to 0 MPH, Side Guard Assist, Lane Departure Warning, and Front Guard Alert — plus Electronic Stability Control, ABS with traction control, Hill Start Aid, and Intelligent Braking Control.
How does TEL help me keep the truck running?
Every unit ships with a 5-year Detroit Connect Core package and 5-year Safety Plus. TEL Fleet Support monitors the data and schedules service proactively — before a small issue becomes a breakdown.
