Why do American trucks have such a big nose and European ones don't?

The enormous "snouted" trucks—the " conventional" ones in trucking slang—that crisscross America's long interstates are not only essential for the unity of the vast country's transportation system, but have also become, thanks to film and television, a true icon of American culture. A culture that has deeply internalized the "bigger is better" philosophy and that makes large volumes, flashy decorations, and chrome-plated vehicles its ultimate expression.

In Europe, they are just as essential for delivering all kinds of consumer goods, but unlike in the US, trucks are always short-cab—technically called "CabOvers"—and in contrast to the exuberance so prevalent in the United States, modest, inconspicuous vehicles are usually preferred.

They are two completely opposite ways of understanding the same type of vehicle for the same function, but where does the difference between the "American" and "European" styles come from?

Either cargo or cabin

The first reason lies in current European legislation, which sets a maximum length limit for trucks of 16.50 meters. This measurement includes both the tractor unit and the cargo bed, so—logically—the smaller the cab, the more space will be gained for the cargo.

For trucks circulating in the United States, however, since the second liberalization of the market in 1982 with the "Federal Assistance Act for Surface Transportation," the length limit refers only to the cargo space, so the length of the cab is irrelevant. In reality, the standards regarding the length of "Class 8" trucks—super-heavy trucks—are a combination of federal and state regulations, as each state can also establish its own restrictions. However, the standard measurement of 13.72 meters, which is in force in the State of Texas, is usually established.

In Europe, professionals must choose between more cabin space or more cargo, while in the US this is not the case, as legal limits apply only to cargo space.

Habitability and orography

Another factor to consider is the enormous distances traveled on average by European and American trucks, as well as the type of roads they travel on. American routes are much longer and mostly consist of wide straight roads, while European routes are shorter, but also narrow, winding, and twisty. For this type of environment, trucks with noses are less useful, as cab-overs offer better maneuverability and visibility. However, since the engine occupies part of the cab, resting space is more limited. Conventional trucks, on the other hand, allow for much larger spaces in the cab for sleeping and resting, as the driver typically spends many more hours on the road.

In the large American Class 8s, the cabins are designed to offer greater roominess and comfort. In Europe, they are designed to be more functional.

Either horses or power

The difference in the type of roads the "heavyweights" will be driving on also marks a third differentiating factor: the mechanics. While American trucks are fitted with Detroit Diesel, Caterpillar, or Cummins engines, which prioritize maintaining a high cruising speed—since they will be tackling less challenging terrain—European trucks like Mercedes-Benz, MAN, Volvo, or Scania prioritize power for precisely the opposite reason, given that they will be traveling across a continent riddled with mountain passes.

Furthermore, the long nose and forward-facing front axle make it easier to access the engine and, therefore, facilitate maintenance—which in many cases is the responsibility of the truck driver himself—while European trucks are always serviced in official workshops.

American engines prioritize speed, while European engines are more powerful and compact, as they must navigate more difficult routes.

Fleets vs. self-employed

In the US, the figure of the "vocational" independent carrier— the Operator Trucker or OTR—is very common. They not only work with their truck, but also—literally—live in it and travel across the country transporting freight for auction. This way of understanding the trucking profession is much less common in Europe, where most heavy transport professionals—even if they are self-employed and drive their own trucks—work either in fleets or under contract to a company. For an OTR driver, therefore, their truck is their hallmark, and personalizing it is part of their essence.

This custom is not as widespread among European truckers, and they don't usually paint or vinyl their vehicles, unless they are owned by a corporate entity, and they prefer more sober aesthetics that don't compromise future customers.

In American trucking culture, the vehicle must be a reflection of the person driving it. In Europe, the image of the truck is always at the service of the customer.
