What is the term for the construction of a bus where the door is positioned forward of the front axle?

The term "cab forward" refers to a specific design in which the bus's engine is located at the rear, allowing the driver’s compartment or cab to be positioned ahead of the front axle. This design not only provides better visibility for the driver but also optimizes the use of space within the vehicle, as it maximizes passenger seating capacity and creates a more streamlined appearance.

In cab forward designs, the forward placement of the cab enhances maneuverability, which is particularly beneficial for urban bus routes. This configuration can also improve safety by allowing passengers to enter and exit closer to the roadside, reducing the risk of accidents involving pedestrians.

Other design terms, such as "extensions," "standard design," or "rear engine," do not accurately capture the characteristics of this bus configuration. "Standard design" typically refers to traditional bus designs without the specific cab-forward feature, and "rear engine" simply indicates where the engine is located, without addressing the positioning of the cab in relation to the front axle.
