Cab over

A "cab over" (also known as "cab-over-engine," "COE," or "forward control") is a body style of truck, bus, or van where the driving cabin sits above (or "over") the engine. This contrasts with a conventional layout where the engine is situated in front of the cabin.

The primary advantage of the cab-over design is a shorter overall vehicle length for a given cargo capacity or passenger area. This is particularly useful in urban environments or areas with length restrictions, as it allows for increased maneuverability and ease of parking. The shorter wheelbase associated with cab-over designs can also contribute to a tighter turning radius.

Historically, cab-over designs were more common in North America and elsewhere. However, regulations favoring longer overall vehicle lengths combined with improvements in engine technology and driver comfort in conventional trucks led to a decline in their popularity in some regions.

Key characteristics of cab-over vehicles include:

• The driver and passengers sit directly above the engine.
• Engine access is typically gained by tilting the entire cab forward.
• Shorter overall length compared to conventional vehicles.
• Enhanced maneuverability in tight spaces.

While less prevalent than conventional trucks in some markets, cab-over vehicles remain popular in applications where space efficiency is paramount, such as urban delivery trucks, refuse trucks, and certain types of buses. They also maintain a significant presence in other parts of the world, notably in Japan and parts of Europe.
