Conventional vs. Cab-Over-Engine (COE) Designs

Semi truck nose types are key in the trucking world. There are two main designs: conventional cabs and cab-over-engine (COE) designs. Each has its own benefits for different needs and likes.

Conventional cabs have a long nose before the engine. They make it easier to get to the engine and are popular with many drivers for their comfort. On the other hand, COE designs put the cab right over the engine. This gives drivers a better view and makes it easier to move around, especially in cities.

Choosing between these designs depends on things like local rules, the kind of routes, and what the driver likes. In North America, conventional cabs are the top choice. A survey by WHITING® Canada showed that 60% of drivers pick conventional cabs for their comfort and how they handle.

In Europe, COE trucks are more common, making up 70% of the market. They work well on narrow roads and in city areas. COE models are cheaper to maintain by about 15% on average than conventional trucks. This is because they have simpler engines and suspension systems.

Feature	Conventional Cab	Cab-Over-Engine (COE)
Engine Access	Easier	More challenging
Visibility	Limited	Better
Maneuverability	Less agile	More agile
Comfort	Higher	Lower
Fuel Efficiency	Lower	Higher

COE trucks have a 10% higher chance of windshield damage from debris. This is because they have a bigger windshield. Yet, both designs keep getting better, making driving safer and more efficient for drivers in different situations.
