Old-School Cool or Outdated Relic? The Rise, Fall, and Possible Return of Cabover Engine Trucks

Once a common sight on American highways, cab-over-engine (COE) trucks were the workhorses of long-haul transport from the post-war era through the 1980s. Today, these flat-faced rigs are rare in the U.S., largely replaced by long-nose conventional cabs. But with changing regulations, urban logistics, and evolving trucking culture, is there a chance we’ll see a cabover comeback?

What Is a Cabover (COE) Truck?

In a cabover design, the driver sits directly above the engine, with no traditional hood. The front of the truck is nearly flat, maximizing cargo space within a given length. These trucks are still popular in Europe and Asia where compact designs are critical for tight roads and urban logistics.

Advantages of Cabover Designs

1. Shorter Overall Length

• The biggest benefit is the shorter wheelbase, allowing longer trailers while staying within legal limits for total rig length.
• Ideal for urban delivery or docks with limited maneuvering room.

2. Tighter Turning Radius

• COEs can navigate tighter turns, alleys, and city corners better than conventionals.
• Great for local, regional, or last-mile delivery work.

3. Better Forward Visibility

• Drivers sit up front with little to no hood, offering excellent road visibility.
• Useful in high-traffic areas or for new drivers learning spatial awareness.

4. Easier Engine Access

• The cab tilts forward for full engine access.
• Mechanics often prefer COEs for serviceability.

Disadvantages of Cabover Trucks

1. Ride Comfort

• With the cab mounted over the front axle and engine, the ride is rougher.
• Bumps, vibrations, and road noise are much more noticeable.

2. Safety Concerns

• In collisions, there’s less crumple zone between the driver and an obstacle.
• Conventional cabs offer more protection in front-end crashes.

3. Cab Entry and Living Space

• Steeper stairs and more effort to get in/out.
• Less room inside for sleeper bunks or amenities.

4. Aerodynamics

• COEs are generally less aerodynamic than modern long-nose trucks.
• Impacts fuel economy at highway speeds.

Why Did Cabovers Disappear in the U.S.?

Before 1982, federal length regulations limited the entire truck and trailer combo. Cabovers allowed fleets to squeeze in longer trailers by minimizing cab length. But after deregulation and the Surface Transportation Assistance Act (STAA), the law changed to focus on trailer length alone.

With no length penalties for conventional cabs and improved engine access in long-nose designs, U.S. fleets began switching en masse. By the 1990s, COEs were mostly gone from the American OTR scene.

Could Cabovers Make a Comeback?

While a full-scale return of cabovers for OTR (over-the-road) is unlikely, they may regain niche popularity in the following areas:

• Urban Logistics: Cities are getting more congested, and smaller rigs with tighter turning could see a resurgence.
• Electric Trucks: Flat-nose EV platforms may revive cabover-style designs for battery packaging and urban fleets.
• Retro Appeal: Some owner-operators love restoring old cabovers for shows, personal use, or brand identity.
• Import Models: Japanese and European cabovers are becoming easier to import as classics.

Still, for long-haul work, ride comfort and sleeper size remain king.

Final Gear Check: Are Cabovers the Future or a Flashback?

Cabovers carved out a legacy of toughness and practicality. They were the right tool for a specific regulatory era. While they may never again dominate American highways, they’re not gone for good either. COEs still shine in cities, yards, and niche roles — and their comeback might be closer than we think, especially with evolving tech and urban demands.
