If you’ve been around the trucking world for a while, the term cab over engine (COE) probably brings back memories of boxy trucks with short noses and tight spaces. These rigs once ruled American roads, especially in the mid-to-late 20th century. Today, they’re making a surprising comeback—and there are good reasons for it.
Let’s take a look at what COE trucks are, why they fell out of favor, and why more truckers and fleet operators are starting to bring them back.
What Is a Cab Over Engine Truck?
A cab over engine truck, also known as a COE truck, is a design where the cab is situated directly above the engine. This means there's little or no front hood—just a flat face staring right down the highway.
Compared to traditional long-nose trucks, COEs offer a much more compact design. This is especially useful in tight urban areas or when navigating narrow roads.
A Brief History of COE Trucks in the U.S.
COEs were once the most common semi-truck design in the U.S., largely due to length laws that limited the total vehicle length. A shorter cab meant more room for cargo trailers.
In the 1980s, however, those length restrictions were lifted in most states. That shift, along with comfort and maintenance concerns, led many fleets to switch to conventional trucks with a hooded design.
While COEs remained popular overseas—especially in Europe and Japan—they mostly disappeared from U.S. highways. Until now.
Why Are COE Trucks Making a Comeback?
Today, the trucking industry is facing new demands, including:
- Urban delivery routes with tight corners
- Increased fuel efficiency standards
- Better maneuverability in crowded areas
- Global supply chain imports using overseas designs
Here’s why COE trucks are re-emerging as a serious option:
1. Space-Saving for Urban Routes
As the industry continues to grow, especially with e-commerce booming, trucks need to get in and out of congested areas quickly. The tight turning radius of a COE truck can be a huge asset here.
2. Easier Maintenance Access (Really!)
Many truckers used to hate COEs for the tilt-cab maintenance setup. But modern designs have improved ease of access, and some models now offer hydraulic tilt systems and better dashboard diagnostics.
Plus, when you’re working in fleet maintenance with medium duty trucks, you’ll appreciate how fast you can get under the hood—literally.
3. More COE Models Available (Especially Internationally)
International Trucks, Hino, and even Mercedes-Benz continue to roll out COE options that are making their way into U.S. markets. These trucks are especially common in logistics operations connected to ports and rail yards.
4. Compliance and Fuel Efficiency
COE trucks tend to weigh less and offer better aerodynamic efficiency, which can help with both ELD trucking compliance and CARB compliant vehicle requirements. Lower weight often means better MPG, and reduced emissions.
Who Should Consider a Cab Over Engine Truck?
- Short-haul drivers working city or regional routes
- Fleet operators looking for better yard maneuverability
- Businesses needing flatbeds or specialty bodies on a compact frame
- Delivery services in urban and suburban areas
If you're still running conventional long-hood semis for routes under 100 miles, a COE could be a better tool for the job.
Final Thoughts
COE trucks aren’t just a blast from the past—they’re a practical solution for modern transportation challenges. With better designs, new technology, and more flexible use cases, cab over engine trucks are carving out their space again on American roads.
If you’re managing a fleet or starting your trucking business, it may be time to take another look at COE trucks. They just might be the space-saving, fuel-efficient, and versatile upgrade your operation needs.
